Phonak Audéo Infinio Ultra Sphere
Important Note: The original Phonak Audéo Sphere Infinio launched in August 2024 and remained Phonak’s flagship model until October 21, 2025, when a free firmware update was released. With that update, the model was renamed Phonak Audéo Infinio Ultra Sphere. If you already own the original Audéo Sphere Infinio, your hearing provider can install the update in just a few minutes. Afterward, your hearing aids will perform identically to the new Infinio Ultra Sphere model. Because the hardware and firmware are the same after the update, we’ve kept all the original reviews for the Audéo Sphere Infinio on this page.

Phonak Audéo Infinio Ultra Sphere — Updated Review & Expert Take

Phonak just dropped the Audéo Infinio Ultra Sphere, a follow-up to 2024’s Audéo Sphere Infinio. At first glance, you’d be forgiven for thinking not much has changed — the devices look identical. But this isn’t a hardware release. It’s a firmware and software refinement, and for anyone who owns the previous Sphere Infinio: you get the upgrade for free.

Yep, you read that right. A quick in-office firmware update, and your 2024 devices will perform exactly like the brand-new Ultra model. Same hardware, same performance, no need to re-buy.

Phonak Infinio Ultra Sphere kit: same reliable hardware as before, now upgraded with smarter software under the hood.

Phonak didn’t reinvent its flagship — it finished the job it started. Infinio Ultra Sphere unlocks the hardware’s full capability through software refinement, not replacement. For current owners, the free upgrade is a no-brainer. For new users, it’s Phonak’s most capable hearing aid to date — same proven design, just smarter in every way.

The Phonak Infinio Ultra Sphere is offered in two technology levels — 90 (premium) and 70 (advanced). It supports hearing losses from mild to profound. It comes in a variety of colors (shown above). The device uses universal Bluetooth connectivity (you can pair up to 8 devices and have 2 active simultaneously) and is compatible with both iPhone and Android via the myPhonak app.

Proven Performance, Now Even Better

When Phonak launched the original Sphere Infinio last year, it made waves — and not just in marketing headlines. The DEEPSONIC chip paired with real-time deep neural network (DNN) processing gave it a legitimate edge in noisy environments.

In fact, independent testing lab HearAdvisor ranked it best-in-class in noise among prescription hearing aids. That matters. Especially because background noise is the #1 complaint people have when it comes to hearing devices.

graph showing phonak performance in speech in noise
The original Phonak Audéo Sphere Infinio (Aug 2024) ranked #1 in HearAdvisor’s speech-in-noise tests. With the Ultra update now live, we expect even stronger results—stay tuned.

Based on what we’re hearing from Phonak, Ultra should sound even better than the original Sphere Infinio — particularly in noisy environments. With the improved deep-neural-network processing, Ultra helps voices stand out more clearly against background chatter while keeping the overall environment sounding natural and lively rather than “muted.”

We’ll know more soon. Our YouTuber Nick — who created one of the most-watched Audeo Sphere reviews online — is currently testing Infinio Ultra Sphere after getting the free firmware update to his 2024 model. Once his video goes live, we’ll post it right here. He’ll break down the “before and after” in detail so you can actually hear the difference for yourself. We’ll be adding his full video review here soon, so be sure to subscribe to our YouTube channel if you want to catch that the moment it goes live.

What’s New With Infinio Ultra Sphere

1. Spheric Speech Clarity 2.0— Improved Deep Neural Network (DNN)

The DNN at the heart of Sphere’s real-time AI has been retrained, now running 30% more efficiently. According to internal Phonak data, this reduces listening effort by up to 35%. Conversations should feel more natural, especially in those unpredictable “chaotic noise” environments like restaurants or large family gatherings. Speech should stand out against background noise a bit more.

Also worth noting: battery efficiency has improved significantly, especially when the most power-hungry program is active. On the original Sphere, using "Spheric Speech in Loud Noise" could drain the battery in just 7 hours. With Ultra, that same use now lasts up to 11 hours. Most people won’t use that program all day — but knowing you have that extra runway is a big deal.

2. AutoSense OS™ 7.0 — Sharper Environmental Detection

AutoSense is essentially the brain of the hearing aid — it’s the system responsible for detecting your environment and deciding how the hearing aid should respond. Whether you're walking into a restaurant, sitting in a quiet room, or out on a windy street, AutoSense determines what kind of sound environment you're in and adjusts settings automatically.

In Ultra, AutoSense has been upgraded to version 7.0, and it now recognizes different listening situations 24% more precisely than before. That means smoother transitions, better focus on speech, and more natural shifts as you move through your day.

The result? Those occasional “pumping” or abrupt shifts that some users noticed in the original Sphere model are now largely gone. Everything just feels more stable, more automatic — like the hearing aid is one step ahead of you.

3. Target 11.1 — Tools for Providers, Benefits for You

This update won’t change how your hearing aids sound — and frankly, most of what’s new here won’t apply to you directly. But that doesn’t mean it’s not important.

Phonak’s Target fitting software is what hearing care providers use to program and fine-tune your hearing aids. Version 11.1 includes a handful of behind-the-scenes upgrades that make the fitting process faster and more efficient:

  • Feedback calibration now completes in under 13 seconds
  • Firmware updates install 40% faster
  • Providers can now disable hands-free calling in high-security workplaces

Here’s why this matters: Anything that makes the provider’s job easier means they spend less time fighting software and more time doing what actually matters — like fine-tuning your settings, answering questions, and helping you get the most out of your hearing aids.

This won’t directly change your sound experience — but it streamlines fitting and servicing, making office visits faster and smoother.

4. Connectivity and App Enhancements

One-step Bluetooth pairing is finally here — and it’s smoother than ever. The new Bluetooth® 5.3 chipset delivers stronger, faster connections with less power draw, and it’s LE Audio–ready, which means it technically supports Auracast™ broadcast audio.

screenshot of the spheric speech feature in the myphonak app
The myPhonak app already held a solid 4.4 rating with nearly 100K reviews—these latest updates make a good app even better.

In theory, Auracast will let users connect directly to shared audio streams in places like airports, gyms, or theaters — no accessories required. But in reality, Auracast isn’t in wide use yet; few public venues are broadcasting, and many phones still don’t support LE Audio as of late 2025. So while Ultra is ready for the future, this feature doesn’t mean much today.

Other refinements include:

  • More stable streaming across iOS and Android
  • Cleaner visuals and faster loading in the myPhonak app
  • Clearer device labels and simpler menus for easier setup
  • Option for providers to disable hands-free calling in secure workplaces

The result: a smoother, more reliable everyday experience with less fiddling and fewer dropouts.

5. EasyGuard™ — Less Maintenance, Same Performance

Phonak introduced a new dome and receiver protection system with Ultra: EasyGuard™. It features a sound-transmitting membrane that you can wipe clean without swapping wax filters. According to Phonak, this can reduce service appointments by up to 38% — and early feedback suggests it’s making a real difference. Less clogging, same sound quality, fewer visits to the clinic? That’s a win.

Design & Fit

Physically, Infinio Ultra Sphere is identical to last year’s model: same shape, same size, same weight: 

Dimensions (L x W x D): 32.2 mm x 9.3 mm x 13.9 mm

Weight: 3.40 grams

Compared to the smallest DNN-equipped hearing aid on the market (like the Starkey Omega AI), Sphere is about 40% heavier and 130% larger by volume. And yes, it is one of the larger hearing aids out there. But here’s the tradeoff: 53x more processing power than the industry standard.

Phonak Infinio ultra sphere on the right ear
When the original model launched in ‘24, we (and likely Phonak) were a bit nervous about the larger size—but it’s turned out to be a non-issue. Very few customers have commented on it, let alone objected.

Personally, I go back and forth — the first time I wore them, I thought, “I’m never not going to feel these.” But a few hours in, I forgot I had them on until a notification chimed in my ear. If you’re new to hearing aids and especially concerned about cosmetics, the size might feel like a barrier. If you’re a more experienced wearer who just wants the best-in-noise performance available, you probably won’t care. My advice? Ask your provider to let you compare Sphere with something smaller, and see which one really fits your priorities.

Pros & Cons

Pros

Best-in-class speech clarity in noise (based on previous results): The original Sphere Infinio (2024 model) was rated #1 in noise by HearAdvisor, beating every other prescription hearing aid tested. That wasn’t just impressive — it was validation. Ultra builds on that same platform with improved neural network performance, so in theory, it should be even better. But until updated test results are released, we’ll hold off on declaring it the new champ.

Improved battery efficiency in noisy environments: On the original Sphere, the “Spheric Speech in Loud Noise” mode could drain the battery up to 3× faster when active. With Ultra, that drain has been noticeably reduced. It’s still something power users will want to keep an eye on during long, noisy outings, but the improved efficiency makes the device far more practical for real-world use. It’s not infinite battery life — but it’s a real improvement.

Free upgrade if you already own last year’s model: If you bought the original Sphere Infinio in 2024, your provider can upgrade it to Ultra firmware at no cost. Same hardware, same performance — just smarter software. It's a rare, consumer-first move in an industry where upgrades usually mean shelling out again.

Cons

Larger than every other comparable hearing aid: These hearing aids are quite a bit bigger than all of the competitors. For first-time wearers, that size might stand out at first. But in practice, most experienced users find the performance tradeoff more than worth it and often stop noticing the size altogether after a short time.

No option for disposable batteries. If you're someone who prefers the simplicity of swapping batteries once a week over daily charging, you're out of luck here. Ultra is rechargeable-only, in line with where the industry is going — but it's still worth calling out.

Auracast is supported, but not active yet. While these hearing aids are technically Auracast-ready, the feature isn’t live. That puts Phonak slightly behind some competitors who’ve already activated Auracast in their devices. To be fair, we’re still early in the Auracast rollout — and most public venues and smartphones haven’t caught up either. But with more TVs, phones, and other devices now shipping with Auracast compatibility, we do wish Phonak had flipped the switch here.

Final Thoughts

Phonak could’ve locked the Ultra firmware behind a new product release and made a lot more money. But instead, they gave the upgrade away for free. That matters. It shows a commitment to long-term value for customers, not just flashy launches or short-term profits.

As hearing aid release cycles get shorter, with new flagships now arriving every 12 to 14 months instead of every 18 to 24, I really hope more manufacturers follow suit. If Phonak keeps leading by example, this kind of move could shift the industry in the best possible direction.

And frankly, this kind of behavior should give you more confidence in buying a Phonak product. If you're someone who values companies that actually do right by their customers, this is one of the clearest examples we've seen in the hearing aid space. If you want to see more of this in the industry, vote with your wallet.

Bottom line? Ultra takes what was already arguably the best hearing aid for noisy environments and makes it even better.

Comfortable, natural sound, and good Bluetooth connectivity

Wearing these new Phonak Sphere Hearing Aids has been very comfortable and an easy adjustment for me. These are my first hearing aids and the sound with them on sounds very natural. I've been able to understand my friends in a crowded restaurant and have been able to turn off the closed captioning on my TV. The Bluetooth feature has worked well for both streaming music and phone calls. I haven't found any drawbacks yet!

My New Ears

All I have ever heard from friends and family about going through the "I'm Getting Hearing Aids" process was how difficult it was to Fit, adjust, noises and so on... Really made me keep putting off taking the "Big" step and go to an Audiologist and find out how deaf I am.. I had to do something COVID has expedited my hearing loss over the last three years so I started doing my research..Went to some box stores and had some conversations and finally went to my ENT and they came back with you can not hear anything.. On the most part TRUE.. Recommended a pair of hearing aids and said if you want to processed come back with the money.. Called ZipHearing and talked with my account manager.. very knowledgeable especially knowing where I am at my age, still active and the problem I am having is very age related.. He sent me to the largest Hearing Practice in my City. They were great.. no wait time, my Audiologist tested again and started then this conversation, not so much about products but me my work, family, church and other working environments. Then we talked about the options and what I can expect from the different products.. I choose the best that was offered and in a little more than a week I had my New Ears.... I cried, no really.. I have missed so much, from wife, Grand kids, Children and co workers... These Hearing Aids are the best.. easy to fit, iPhone ready adjust with one click.. quality.. My TV went for Volume of a 20 to an 8. Quality, I have drop the CC on most shows.. From Charging to the way they look (you really do not see them from the from and side and if you wear glasses you do not notice them from the back.. I am so thankful that found a group that could walk me through a difficult process for me and find me the best product a more that half the price with all the same support and in addition provided the replacement insurance where the other provider it was not included.. Call these folks and start hearing again.. My Life has gotten sooooo much better and I Fight a lot less with my BOO... War Eagle..

Best I have ever worn

I can say without a doubt these hearing aids are the best I have ever worn. Where they really shine is hearing situations that have loud background noise. Example: I went to a grandchild’s birthday celebration that was held in an arcade. Normally, I would struggle hearing in such a situation but found I had no problem at all. I was blown away at how well they performed, technology is wonderful. They are slightly larger than my previous ones but I have not had any problems, even wearing glasses. This my second time buying aids using Zip Hearing and like last time it has been great. Saving money is always a good thing!

Great hearing aids, but frustrated

I am currently wearing the Phonak Audio Sphere 90 hearing aids. Had them about two weeks now and the sound quality is very good. I am a bit frustrated with the Automatic program selection as it does not really seem to pick the correct program for the situation. I have not noted the sphere function working as of yet, even though I have been in a few very noisy situations. They are comfortable and only took a few days to adapt to the thicker design of the body. The battery life is exceptional. After wearing them for 15 to 16 hours they still have 45 percent batter life. The only other complaint is the charger case. It is not easy to get they in and almost kink the wires to the domes. I wish they were bigger like my previous Marvels.

A good upgrade from ReSound to Phonak Sphere

I have been wearing hearing aids for 6 years. I started my journey with ReSound which lasted nearly 5 years. I then went to Costco and discovered Costco aids are fine for people with modest hearing loss, but I needed more. I then went with Phonak Sphere and have been very happy. I am active and discovered early on the aids I had purchased were being negatively impacted by sweat. Phonak replaced them with water resistant aids for a very small charge. I am very pleased with my new aids.

Good experience with ZipHearing and easy upgrade process

After much research I decided to try Zip hearing and settled on a pair of Phonaks. After a fitting I was completely satisfied. Within 5 weeks of my purchase Phonak upgraded their line to Audeo Sphere Infinio 90 with much better updated features. I called ZipHearing and they immediately sent the new devices to my hearing provider for exchange with no problems. I found Derrick with Zip and the audiologists extremely easy to work with and knowledgeable.

I hardly even notice them

Hi, my name is Larry. This is my hearing story. We are now living in Arkansas. We moved here about two and a half years ago from Iowa, and about 6 or 7 years ago I realized that I was going to need some help with my hearing. After many years of hunting and shooting and some construction work, my hearing was not good. I sought out several companies and found one that really evaluated me very well, and what they recommended were very expensive, but I could do them over a payment plan. And so I went ahead and bought these hearing aids, and they came with annual checkups, and they came with free batteries and had about a three year warranty on them. I was very happy with them. They even had a connection with an app with my iPhone, and I could make the adjustments there myself in certain environments and after we moved here to Arkansas, I lost the contact with that company and also the warranty had run out on it, so I knew I was going to have to get them replaced and so I started doing some research and I ran across a very well advertised hearing aid company. But they had no facilities here in little Rock area, and I really wanted someone that I could be in contact with. I discovered Zip Hearing, and they carried 3 or 4 brands and made an appointment with their hearing specialist up in little Rock, and we went and she did a hearing test on me, and it turned out to be a recommending some of the Phonak brand hearing aids. These came with a really nice little case here and this is actually a charging unit. And you can plug them in on the back side. And these units are very attractive. They're really pretty simple. And I really like them. They're very comfortable. I hardly even notice when I'm wearing them. I do notice when I'm not wearing them because I can't hear nearly as well. What I like too is these came with the app, but they are rechargeable, which I don't ever have to mess with batteries again, and they can control the environment around you, I like that, almost automatically. Get into a say, a restaurant situation. I can hear people talking around me without all of the exterior noise and all of that. So, even though they were expensive, they were still less money than what I had ended up paying, almost 6 or 7 years ago. And the advancement has been considerable since then. So I'm really recommending these hearing aids. I would recommend that you contact Zip Hearing and they'll put you in contact with the right people and, happy listening.

They changed my life

Hi, my name is Theresa and thought I'd take a break from work and talk to you about my new hearing aids. I personally have never had them before, but as I reached the age of 60, what I was really having trouble with was some tinnitus, as well as maybe a bit of hearing loss that I suspected and while I hadn't personally had them, my first husband did have them, so I was very well acquainted with how much they make a difference in someone's life, especially in their social relationships and things and I didn't want to lose that at all. So, I wanted to be proactive. So, the hearing aids that I chose are the Phonak Audio Sphere. I chose the 90 version, which is their top of the line, I believe it is very lightweight, as you can see, it's pretty thin. I wear glasses already, so for me, having something behind my ears wasn't a big deal. I was a little afraid that they would be difficult to put in, you know, as a newbie, but I just toss it back there and then take the little cone and put it right there, and the tail end kind of flips in and frankly, they just stay wonderfully, especially right up against my glasses. They're fine and one thing I really like is that nobody knows that I have them on. I thought for sure, you know, people would see, you know, the little, oh, it's almost like fishing line there, but nobody notices. I have a charger, so I never have to buy batteries. Yay! And, I love having that convenience. One thing that I wanted to mention too, was that while I had trialed them originally through a certain local audiologist, I ended up going through Zip Hearing and purchasing them that way and no lie, I saved $3,000 by doing that. So, I would highly recommend that. And they gave me a little special bonus, so be sure to ask them about that if they're still offering it at least. One thing I love about these hearing aids is that they're really cutting edge technology. I've always been an early adopter of anything that, you know, comes up, I want to be one of the first to have something, and these are the first ones that have AI to help you filter out the background noise. And of course, that's something that, you know, people with hearing aids always talk about is background noise, or people with hearing loss in general, just having difficulty with that. And so, this makes it a lot less of a problem. And there's really nothing that I don't like about these. Probably, but that's the same with any hearing aid is that, you know, you've got to take them out if you take a nap or whatever, you know, you're not going to lay on them. But, that's a rare thing or like you're laying down to watch TV. But, yeah, that's probably the only thing, but it's with any hearing aid, obviously. So, but no, I really like how much they have changed my life, even just in the 3 or 4 months that I've had them. Let's just put it this way. I forgot them and didn't wear them to work yesterday, and I noticed. So, well, best of luck on your journey and, deciding which ones to purchase.

Common questions about Phonak Audéo Infinio Ultra Sphere hearing aids

Bluetooth / Connectivity Rechargeability Controls/Apps Miscellaneous

Choose questions category:

Is this hearing aid Bluetooth compatible?

As of the August 2024 release, Phonak Audéo Sphere Infinio uses Bluetooth 5.3 and is compatible with nearly all tablets and phones for the direct streaming of music, phone calls, and more. You can check your device compatibility with Sphere hearing aids here. Sphere hearing aids are also Auracast™-ready. Auracast is a new Bluetooth feature that will allow multiple devices—like hearing aids—to share an audio stream. In the coming years, as public venues like airports and theaters install Auracast transmitters, that means Sphere users will be able to stream that venue’s audio directly into their hearing aids. When Phonak is ready to enable the Auracast feature in these hearing aids, it will require a visit to your hearing care provider’s office for a firmware update. We believe—though we haven’t received a clear answer yet—that when this update happens, Sphere hearing aids will also be upgraded to use the Bluetooth LE Audio specification.

Does this hearing aid allow for hands-free phone calls?

Yes, Phonak was the first brand to implement this technology in 2017. That makes Audéo Sphere their fifth generation hearing aid to have this feature, and it shows. Hands-free calling is simple to use, and it essentially turns the hearing aids into a wireless headset. When you have an incoming call, you will hear the phone ringing through the hearing aids. With the tap of a button on the hearing aid (or by accepting the call on the phone) you can then answer the call and just start talking—you will hear the caller through both hearing aids. You can keep your phone in your pocket, or even on the other side of the room, and your voice will be picked up by the microphones on the hearing aids so the caller can hear you. This feature works best in quiet environments. If you use hands-free calling when you're outdoors or in a noisy environment, the caller on the other end may say you sound like you're on speakerphone. If you’re ever struggling to hear the caller over background noise in your environment, Phonak has included a nice feature in the app called Environmental Balance. While on the call, you can open the app and use this feature to adjust streamed signal volume against the surrounding environment volume. The call can be ended either traditionally on the phone or with a long push on the push button.

Can this hearing aid be paired directly to my Bluetooth TV?

If your TV supports Bluetooth audio output—and most TVs from the last 5 years do—you can pair your Sphere hearing aids to your TV. However, Phonak doesn’t recommend this, as users often experience excessive battery drain. For better sound quality, a more reliable connection, and reduced battery drain, Phonak suggests using their TV Connector accessory (shown below on this page). This small device plugs into your TV’s audio output, typically via the optical out port, and streams sound wirelessly to your hearing aids. A notable feature of the TV Connector is that you can control the volume in your hearing aids independently from the TV’s speakers. This allows you to adjust the volume to your preferred listening level without affecting the volume for others in the room.

Is this hearing aid Roger compatible?

Yes. All Audéo Sphere Infinio models can pair directly to Roger devices. In most cases we’d recommend the Roger On 3 device (read more on that below), as we’ve found it to be the most versatile Roger device that meets most of the needs and use cases of our customers.

How many hours a day do the batteries last?

We wish there were a clear answer, but battery life depends on several factors. It can be affected by how hard your hearing aids are working, which depends on your level of hearing loss and the acoustic environments you’re in. It can also be influenced by how much (if any) Bluetooth streaming you do (like from your phone or TV).

In general, based on reports from our customers, here’s what you can expect: assuming your hearing aids were fully charged the night before and that you don’t do any Bluetooth streaming, you can expect 20–24 hours of battery life. Phonak reports that with 3 hours of Bluetooth streaming a day, you’ll still get around 16 hours of power. We have heard from our customers that, in general, an hour of Bluetooth streaming reduces battery life by about 2.5 hours. So if you consider that the default battery life with no streaming is about 24 hours, 1 hour of streaming should leave you with 21.5 hours.

But wait—it gets trickier! The Audéo Infinio Ultra Sphere is the most power-hungry hearing aid Phonak has ever made, thanks to the computational power of the deep neural network (DNN). The battery will drain at a faster pace than normal when you’re in noisy environments. For this reason, we recommend keeping a close eye on your battery charge status (available inside the myPhonak app) before entering a noisy situation. If you’re going to be in a noisy environment for several hours, we suggest ensuring your hearing aids have at least a 40% charge before entering.

Does the charger include a dehumidifier?

Chargers for earlier Phonak models used to include space for a desiccant/dehumidifier puck. In recent years, including with the Audéo Sphere, Phonak chargers no longer offer this option. Phonak explains this is because the newer models are IP68-rated, meaning they can technically withstand complete submersion in water, so regular exposure to moisture, sweat, and humidity will not affect the hearing aids. If you are concerned about this, you could consider something like the PerfectDry Lux (download info here), a dehumidifier that, within 45 minutes, removes moisture and uses a UV-C lamp designed to sanitize the hearing aids with ultraviolet (UV) light. This accessory can be ordered through your Phonak provider.

Why does the app show the battery depleting faster on one aid?

This is totally normal for Phonak hearing aids and has been for several generations of products. One of your hearing aids actually establishes the initial Bluetooth connection with your phone/tablet/etc, and then relays the audio stream and other information to the other hearing aid. Whichever hearing aid makes that initial Bluetooth connection will drain slightly faster than the other aid.

What is the lifespan of the rechargeable batteries?

Phonak says they will last at least 5 years. Based on past reports from our customers who used previous generation Phonak models, we think that's a bit optimistic and would recommend counting on 3–4 years. The battery is built into the hearing aid, so when it needs to be replaced, your hearing care provider will ship the hearing aid to Phonak and Phonak will replace the battery. Most people have a 3-year warranty with their hearing aids, so by the time the battery needs to be replaced, that is unfortunately outside the warranty period. This means Phonak charges your hearing provider, and your provider passes that charge along to you. Expect that price to be somewhere in the range of $150–$300.

How will I know when my battery needs to be charged?

About an hour before your hearing aids power down due to a low battery, you’ll hear a few low-pitched descending tones alerting you to change the batteries. The way the tones sound will indicate that they’re signaling a low battery (and it's pretty obvious) but you can also ask your Phonak provider to demonstrate this sound with you in their office. 

How long does it take to get a full charge?

Your hearing aids will fully charge in about 3.5 hrs, giving you 24 hours of power. If you're in a pinch, every 15 minutes of charging will get you over 1.5 hours of battery life. 

What if I'm on-the-go and my battery dies?

This is unlikely to happen, as even with several hours of Bluetooth streaming your hearing aids should last 16 hours a day. Sphere hearing aids use a built-in rechargeable lithium-ion battery, so if your batteries do run out early, your only option is to charge them back up.

Charging is pretty quick—they take 3.5 hours for a full charge. But if you’re in a pinch, every 15 minutes of charging will get you over 1.5 hours of battery life. 

If you’re concerned about this happening, we would recommend buying a separate ChargerGO RIC Sphere I (you can see it on this page), that way you can keep a charger in your car/purse/etc for when this happens. The charger comes with a USB-C charging port as well as a wall plug for flexible charging. 

Since you get one charger included with your order, you can keep one of your chargers at home for more stationery use, to be charged nightly, and another that is your portable charger.

How can I control this hearing aid, and which settings can I control?

You can control the volume and program via the rocker switch button on the hearing, the RemoteControl accessory, or the myPhonak app. The myPhonak app will also allow you to adjust the bass, mid, and treble frequencies of the hearing aids. There is also a new slider control in the app that adjusts the strength of the DNN speech clarity and noise reduction. So, if you decide you need a little bit more help in this environment, you can bump up the strength of the DNN processing.

How do I turn this hearing aid on and off?
Press and hold the onboard rockerswitch's bottom button down for 3 seconds to turn it on or off. Or, simply place the hearing aid in the charger.
Does the app have a “Find My Hearing Aid” feature?

This feature was not available at the time the product was released in August 2024, but as of October 2024, this feature now exists in the myPhonak app. In order to use this feature, you have to activate it either when you initially setup the app and pair it to your phone, or at a later time. When wearing your hearing aids, if one falls out or is far away from the other device, you’ll get an audible alert through the hearing aids (your hearing provider can demonstrate this tone for you so you know what it sounds like). 

The myPhonak app will also show an alert in the app that an aid has become disconnected, and you’ll be able to pull up a map with the disconnected hearing aid on it showing the last known location of the aid—the last location at which the aid was paired to the phone. Once you are within 32 feet of the lost hearing aid, your phone will receive a signal from it, and you’ll see 5 bars displaying the current signal strength. Then, it’s essentially a game of hot and cold, where the closer you move to the hearing aid, the more bars you will see, indicating you’re getting closer to the hearing aid.

Note that in order for the app to receive the signal strength from the hearing aid, the hearing aid must still be “on”, so it’s important that if an aid is lost, you use the ‘Find my hearing aid’ feature as soon as possible. Once the battery runs out on the aid and it powers down, you’ll still see the aids last known position in the app, but you won’t get the signal strength bars to help you hone in on the exact location of the hearing aid.

Is this hearing aid CROS compatible?

It is not. However the standard Audéo Infio model (non-sphere) is CROS compatible, and Phonak is reporting that battery life is drastically improved on the CROS, as this was a complaint with their previous generation CROS transmitter. 

Does Audéo Infinio Ultra Sphere have a telecoil?

No. Sphere hearing aids are Auracast™-ready, and that technology is going to—for the most part—replace telecoils. We expect most manufacturers to phase out telecoils in the coming years as Auracast gains popularity, which is slowly happening.

When will Audéo Infinio Ultra Sphere be available in the 50 and 30 technology levels?

As of October 2025 Phonak does not have plans to release the Sphere model in these lower tech levels. You can however buy Phonak Audéo Infinio Ultra (non-Sphere model) in the lower tech levels, but you won't get the benefits of the deep neural network technology.

TV Connector, $279

Plug it into the back of your TV or soundbar and the audio will be streamed directly to your hearing aids. Others can keep the TV at their preferred volume level, while you set your own volume via the app, on the hearing aids themselves, or via the + or - buttons on the TV connector.

RemoteControl, $249

You probably don't need this. Most people use the app to control their hearing aids, and if not the app, then the push button on the hearing aid itself. But if neither of those suit you, this remote is a simple way to control the volume and program.

KEY FEATURES

1. Dome

The image of Dome hearing aids feature

The dome slips over and encloses/protects the receiver/speaker. Domes are made with medical-grade silicone. They come in different shapes and sizes. Your hearing care professional will help you pick the right size and style. The hearing aid programming software can make size and style recommendations as well with the new AI Dome Proposer feature, which is trained by AI and real-world data from audiologists to recommend the optimal dome. Selecting the appropriate dome will change the sound performance of your hearing aids, so if you’re not achieving satisfying results with your hearing aids, your hearing provider will often consider trying a different dome style. In some cases, such as for wearers with severe or profound hearing loss, an earmold will be used instead of a dome.

2. Indicator light

The image of Indicator light hearing aids feature

The LED indicator light shows the charging state of the battery. 3 red blinks means the aids are 10% charged, 3 orange blinks 11-80%, 3 green blinks 81-99%, and a solid green light means the aids are fully charged.

3. Microphone

The image of Microphone hearing aids feature

The microphone picks up the sound from the environment and sends it into the hearing aid for processing. You’ll mostly want to leave the microphone alone, but periodically check it to ensure it’s not being plugged up by hair care products or oils.

4. Receiver

The image of Receiver hearing aids feature

The receiver AKA speaker delivers the sound into the ear. Phonak receivers are available in 3 different strengths, standard (S), moderate (M), power (P). Your ZipHearing provider will help you determine the appropriate gain (strength/power) receiver based on the results of your hearing test. Expect to have to replace your receivers every year or so, and this is something that usually takes just a few minutes with your local ZipHearing provider.

5. Receiver wire

The image of Receiver wire hearing aids feature

This thin, plastic-coated wire transmits power and signals to the receiver/speaker, which is worn inside the ear. Phonak receivers are available in 5 different lengths: 00,0,1,2, & 3. Your ZipHearing provider will help you determine the appropriate length of receiver wire, by measuring your ear. In cases when your ZipHearing provider is unsure of the exact receiver length that will work best for you, we’re happy to send out a few different receiver lengths for you to try.

6. Rechargeable battery

The image of Rechargeable battery hearing aids feature

Audéo Sphere Infinio is powered by a rechargeable lithium-ion battery, expected to last 16-24 hours/day. The battery takes about 3 hours to fully charge, and a 30 minute quick charge will get you about 6 hours of power. Simply put the aids in their charger at night and you will wake up with fully charged hearing aids that will last all day.

7. Rocker switch

The image of Rocker switch hearing aids feature

The rocker switch can be programmed by your hearing provider to have different functions, depending on your needs. Some of these functions include volume and program control, on/off functionality, flight mode, answering/ending phone calls, pausing/resuming streaming, and accessing virtual assistants like Siri. Some people use these buttons exclusively to control the hearing aids, and others use the app to control the hearing aids. Others (most people), use a combination of both the app and push button to make adjustments to their hearing aids. You likely won’t have to use these buttons often, but some people find them handy to make quick adjustments to their hearing aids when they change listening environments (ie, entering a noisy restaurant, or a quiet room). Your hearing provider will go over the options available and make sure your hearing aids are set up to your ideal preferences.

8. Wax filter

The image of Wax filter hearing aids feature

When it comes to maintaining your hearing aids, this is where you’ll spend most of your time. The wax filter (mostly) prevents wax and oils from getting into the receiver/speaker. Your hearing provider may supply you with Phonak Cerushield filters enabling you to periodically change these on your own. Some people never have to change these wax filters, others have to change them weekly. Your purchase includes 1 pack of wax filters, and you can purchase additional wax filters directly from your ZipHearing provider, or through a number of sites online such as Amazon.
