Frequently Asked Questions
LiNX Quattro rechargeable hearing aids are built with premium quality custom Lithium-ion batteries that provide up to 30 hours of use from a single charge - or 24 hours of use with 8 hours of wireless streaming! Finding the opportunity to recharge LiNX Quattro is really easy, because the portable charging case included with the hearing aids can provide three additional charges on the go, without connecting to an electrical outlet. Three hours is all it takes for a full charge, but when you just need a little power to keep the hearing aids going, you can get it fast. Just 30 minutes of recharging will deliver up to eight hours of hearing aid use.
No. LiNX Quattro is not available with a telecoil. Except in situations where a telecoil is the only option, wireless streaming is usually preferable, because it provides better sound quality and allows stereo audio.
The manufacturer suggests that the lithium-ion battery will last approximately 4 years before needing replacing.
To turn your Quattro rechargeable hearing aid on or off, simply press and hold the push-button for 5 seconds. If you take the hearing aids off and put them in the charger without first turning them off, then when they are pulled out of the charger, they will automatically be on.
Accessories & Smartphone Apps
Li-ion Charger (included)

With its small, discreet size and long-lasting battery, the ReSound LiNX Quattro charging case gives you get power that lasts more than a full day, without having to fiddle with any batteries. The portable case’s built in battery holds enough reserve for three full charges of power—perfect for a weekend away!

Smart 3D App

Take control of your hearing aids. Adjust sound settings such as volume, program, base, treble, and even create custom programs based on specific listening environments. Use the app to find your hearing aids if you lose them, check the status of your rechargeable battery, and provide soothing sounds for tinnitus relief. In some cases, your hearing provider can even make remote adjustments to your hearing aids through the app.

Phone Clip +: $259

This is a Bluetooth streamer that allows you to stream audio from your phone to your hearing aids. If you have an iPhone, you don't need this, because iPhones directly stream to ReSound hearing aids. If you have an Android or any other phone and you want to stream from your phone, you need this. Even if you have an iPhone, it still may make sense to get this, because it does allow for hands free phone calls. Wear it around your neck and the microphone picks up your voice for the person on the other end of the call to hear, so you don't have to hold you the phone to your mouth when speaking. The streamer also doubles as a basic remote control, allowing you to change the volume and programs of your hearing aids.

TV Streamer 2: $379

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

Multi Mic: $359

All the functionality of the Micro Mic, but with the added benefit of also working as a table microphone. When placed horizontally on a table or flat surface, it'll pick up the voices of multiple speakers and stream them directly to your hearing aids.

Micro Mic: $269

If you have a hard time hearing in noise this accessory is a lifesaver. Attach this microphone to a companion's shirt and their voice will stream directly to your hearing aids. Their voice will come through much stronger than all the competing noise in the environment.

Remote Control 2: $239

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, with a helpful display screen so you can easily see your hearing aid settings.

Remote Control 3: $239

Adjust the volume and program of your ReSound hearing aids easily and discreetly. The simple keypad style design features large buttons, which are concave, tactile, and ergonomic. The buttons have raised symbols in the center, so they are easy to locate and glide a finger over. The standard CR2032 Lithium coin cell battery is widely available and easy to replace.

Control App

If you have an iPhone or Android, you don't need this app. If you have any other phone and you wish to use an app to control your hearing aid volume and program settings, this is the app for you. The Phone Clip + accessory is required for use with this app.

I've been wearing the ReSound LiNX Quattro 9 Rechargeable for approximately 2 weeks.
This is my first hearing aid, but I did have a 2 week trial of the Widex 440 F2 prior to purchasing the ReSound.
The ReSound is easy to insert and remove; I've had no difficulties with that aspect of the product at all.
I have worn it continuously for up to 18 hours. I find it to be very comfortable; there have been several times I've forgotten that I had them on.
They charge quickly and hold charge well so far. Streaming audio with Bluetooth does indeed impact charge longevity. I haven't yet done a lot of experimenting with how quickly streaming depletes the charge.
I have an phome running Android 9 so I have to use the Clip device for streaming. I expect the phone will update to Android 10 in early 2020, making the Clip unnecessary.
So far, I am very pleased with the sound quality. We are still in the process of tuning the device to match my needs, so it will only get better.
I think the device may need some work on streaming performance. I occasionally experience 1 second dropouts on either side from time to time when listening to music or audiobooks. Other devices connected to my phone via Bluetooth do not exhibit these dropouts so I know it its the hearing aids. These is nothing unusual going on when those dropouts occur (not low on charge, no interference from nearby Bluetooth devices, the Clip is with definitely within range, etc.).
Streaming sound is not as good as I expected, but I think I know why:
My hearing needs a boost on the higher frequency ranges, so when streaming plays, that is what the hearing aids do. During normal (i.e. non-streaming) use, the hearing aids provide a higher frequencies supplement to the lower frequencies from my normal hearing. Streaming therefore sounds different because I'm not getting the low frequencies anymore; the hearing aids are acting like hearing aids, not ear buds or headphones.
So, it would be nice if when the device is being used in streaming mode, that the frequency range could be expanded to make it sound more like an ear buds or headphones.
I'll have to talk to my hearing professional and/or ReSound to see if this is possible.
Overall, I like the product. It definitely improves my quality of life which is my primary objective.

The most amazing thing about the Resound Quattros is the rechargeable batteries!! Great innovation and convenience for the user. No more batteries. The sound quality is unparalleled and resembles natural hearing.

These hearing aids were constantly fluxuating all of the time. The hard shell that was made was very comfortable and did not cause noises. The "mike" worked fine but did not reduce the background noise. Just talked over it. You need a rocker for the left ear for choosing the program and a rocker for the right side to control the volume. The button process is way to cumbersome. I have returned these to my vendor for full credit.

I really like my new Resound hearing aids. The work with no issues. I like the fact that they can connect to my iPhone. They work real food with the iPhone the voice on telephone calls is clear and I like listening to music on my iPhone through my hearing aids. I especially like that they are rechargeable. This is very convenient and I do not have to carry around extra batteries on my keychain. If I do not do a lot of streaming the battery seems to only come down abut 50% during the day and I recharge it over night is it is ready to go the next day. These are the best hearing aids I have ever had.

Excellent sound quality - full and rich. Highs are particularly clear. Streaming of music and telephone calls is great. Phone application is full-featured and allows easy adaptability to a variety of listening environments/acoustics. Only suggestion is that ReSound should include a tone that identifies when volume is returned to preset level.

First, these are my FIRST hearing aids. I had my hearing tested and the ReSound was recommended based on the hearing test. That being said, I wanted a rechargeable hearing aid. After much research I settled on the ReSound Quattro 9. Granted, I have only had them for 2 weeks but the sound quality is great, the phone app. makes changing the programs and "tweeking" the base, treble etc. very easy to adapt to the environment.
Batteries: My audiologist was not sold on rechargeables due to poor battery performance. I have yet to get the battery level down to two bars. For the first week I tracked when they were put in and checked the battery level throughout the day. One day they were in at 7AM and out at 10:30PM and listened to some music AND had a 35 minute phone call. The batteries are GREAT and perform as promised.
Phone: Galaxy S9+ so I purchased the Phone Clip+ Pros: Rechargeable batteries, excellent sound quality, phone app is easy to adapt to, add programs etc., paired with bluetooth no problems, can recharge on the go with no power up to 3 times. Noise/Wind reduction works as promised.
Cons: Have not been able to add Icons to the app when I add a program, only get a star. The app disconnects a couple of times a day (just close and restart) I cannot say enough about the Quattro 9's. I have nothing to compare to but I don't see how these can get any better.

After speaking with several friends who use hearing aids I have come to the conclusion that in the same price range, the products are similar and as long as they all use the same ten bands of adjustment, the measure of how much I like them is based on the level of support provided by Zip, the audiologist and the manufacturer. That said, the ReSound product works and my children have stopped complaining that I am difficult to speak to. Without support, they would have stayed in their box. I tried to connect my ReSound hearing aids to my Apple Watch. It turns out that the ReSound application installed on my watch only works if the watch is near my phone. I asked the Apple sales person about this and they described the design as a ‘leech’.

The sound quality is excellent - when they are working. I have had issues with one or both hearing aids shutting off on their own. Therefore, I would not rate the reliability very highly at this point. In fact if the problems persist I will be returning them before the end of the trial period.When they are working properly, the pros are: sound quality is excellent, even in noisy or windy environments; there is no feedback squeal; the integration with iPhone has drastically improved my ability to hear on phone calls.The cons are: the initial cost; unreliable performance at this point; and the difficulty in finding a local qualified audiologist, although I am very satisfied with the audiologist we were eventually able to find at some distance from my home.

I have worn Rexton and Kirkland hearing aids for ten years. Both were 'OK', but I decided to give the BTE ReSound LiNX Quattro 961's a try, and the difference is amazing! The clarity of speech has improved many levels and my Tinnitis is less noticeable. I no longer have to ask my wife "what?", or rewind the TV program because I missed what was said. I can use the Bluetooth function to answer my phone and stream music or news. And I can adjust the volume and change programs in the Aides from my phone. The sealed lithium ion rechargeable batteries last over 12 hours on a charge, and the included portable charger is also fantastic. The charger is 3.75" by 2.5" by 1.25" and can be carried in your pocket (if you want to). It provides several days of additional charges. And perhaps the best thing...because they are so comfortable and my hearing so improved, I find myself wearing them from the time I get up until I go to bed. I only regret not buying these sooner!

I am now hearing for the first time in 2 years. Wow have I missed a lot!! I am now wearing a pair of Resound rechargeable hearing aids. I am loving them. Sound quality is great. The getting used to them was very easy and quick. After a couple of visits for adjustment I no problem using them. The local service was amazing. I would recommend these to anyone!! I no longer say what when someone talks. I wish I had done this sooner. Thanks Zip Hearing. I really enjoy the product!!!

Doesn't help much to stop wind noise. Can still hear the ringing in ears.
Fit is very good, confortable, and light weight.
Sometimes the charger doesn't fully charge the units.
Easy to keep clean. Charger is small and easy to transport.
The iphone app allows me to make necessary changes easily. Not easy to adjust units without app.

I considered my word recognition ability to be beyond improvement because I have been to a number of audiologists that said they couldn’t help me. While I will never have full word recognition I can honestly say that Resound aids are the best I’ve tried in the past 10 yrs. Their app is easy to use with the aids and the key is to have an experienced provider that can give you a base setting that minimizes the need to manipulate the app features. Mine has done that.

They are convenient though the right one is irritating at the end of the day because the bud does not fit comfortable in that ear canal which is curved inwardly. Also the low volume starting point is too loud when sitting near my wife's high pitched voice in the car. I am getting use to the high volume ring when a call is coming in and the phone is not with me as it is being charged or in a pocket. I have to recall where it is and run to get it that's a new experience and my retraining is underway. Clarity is very good compared to former aids and in that respect I am pleased. The audiologist was excellent, thorough and competent. I look forward to the next appointment for the minor adjustments. The guide book was little help in syncing the TV blue tooth transmitter and understanding the iPhone controls. For example the warning that the insertion of the buds needs to be done with care is exactly opposite the that required with the air tubes I formerly had air tubes those needed to be wiggled and pressed during insertion.

These hearing aids have been wonderful for me. Most of the time I forget that I have them on. The sound is crisp and clear, and the ability to fine tune to my environment with the ReSound app is a real bonus. Add that to an extended battery life and quick recharge time, & I could not be happier, Thank you!

Being a first time hearing aid user I was reluctant to buy them. It has changed my life for the better. The resound Quattro is amazing n easy to use. I just set them in the charger overnight n I'm ready to put them on in the morning for all day. Having Bluetooth n pairing them with my phone is easy n fun. The ab that goes with this hearing aid is so easy. No regrets.

The app doesn't work properly with my cell phone - a Samsung Galaxy S9.
Keeps disconnecting from hearing aids, which requires shutting off my cell phone and restarting it to reconnect. This is an annoying- and sometimes dangerous -distraction.
Also it interferes with my cell phone regular usage- calls get static or go dead,etc.
I may have to return the hearing aids.
This is a serious problem.
