ReSound One 9 Hearing Aid Description & Features

Every once in a while, a hearing aid comes along that challenges the status quo- that goes against the grain and attempts to do something that's never been done before.

That is the story of ReSound ONE.

For more than a decade, the physical build of the most popular style receiver-in-canal (RIC) hearing aid, has remained relatively unchanged.

Sure, design technology has improved- they've become more water and dust proof, they're available in more colors, and designs have become more sleek, but the core build and logic behind the hearing aid has not changed, until now.

ReSound ONE is the first hearing in the world to add a microphone on the receiver (speaker) which fits inside the ear. That means (like traditional RIC hearing aids), there are 2 microphones on the hearing aid itself which sits behind the ear, but now there's also a third, at the opening of the ear canal.

Why would ReSound do this?

Adding an additional microphone at the ear canal opening allows wearers to localize sound better and tell the direction from which sound is coming. As one might expect, adding this additional microphone helps wearers hear in a way that is more natural, and more similar to the natural ear in it's ability to funnel sound into the ear canal.

The logic is solid, and the customer response has been overwhelmingly positive. Will this be something that's adopted industry-wide? It's too early to tell, but it doesn't appear that it's something that will only last on this generation of ReSound hearing aids.

The unit pictured above is the ReSound ONE rechargeable hearing aid, but this aid can also be ordered with a disposable size 13 battery, or a smaller size 312 battery.

The ReSound ONE 9 is ReSound's best hearing aid, they call it their "ultimate" technology level. If you lead an active lifestyle and demand the utmost in performance from your hearing aids, ONE 9 is an easy choice.

It's a premium hearing aid, so inline with all the other major manufacturers, it offers 17 channels, and 4 customizable programs. That means this hearing aid can be precisely fine-tuned by your hearing care provider to match your hearing needs and lifestyle perfectly.

While most wearers will use ONE hearing aids with a silicone dome like shown in the image above, this aid may be worn with a custom earmold from ReSound, which would then make it a suitable choice for individuals with severe hearing loss.

Frequently Asked Questions about the ReSound One 9
The ReSound One 9 is a Made for iPhone hearing aid, and is compatible with all Apple devices. It will also work with some Android devices. Before purchasing, we recommend checking your phone's compatibility on ReSound's website:
ReSound says the rechargeable battery will last 25-30 hours on a full charge, depending on how much audio streaming you do from your TV or Bluetooth device. The battery should last for about 3 years. Before your 3 year warranty expires, we recommend sending your hearing aid to ReSound for a battery replacement.
Much of the hype around the ReSound One hearing aids is related to their innovative new M&RIE (Marie) receiver. This receiver has both a microphone and speaker inside the ear, and according to ReSound, this helps users localize sound in a more natural way. However, these M&RIE receivers are not included by default with your ReSound One orders. If you want M&RIE receivers, please let us, or your ZipHearing provider know at time of ordering.
It does not. In order to talk hands-free on the phone, you would need ReSound's Phone Clip + accessory (below). This accessory clips onto your shirt and is what picks up your voice so the caller can hear you. If you don't want to use the Phone Clip, you'll still be able to hear the caller through your hearing aids, but you'd need to hold the phone to your mouth as you normally would, so the caller can hear your voice.
Only via the ReSound TV streamer 2. Even if your TV is Bluetooth compatible, it will not connect directly to ReSound ONE hearing aids without the TV streamer.

Overal Ratings: 4.44 out of 5

Based on 9 User Reviews

ReSound ONE 9 is my first hearing aid I've ever bought, so bear in mind that I have nothing to compare the ONE 9 to. Having said that, the pair of ONE hearing aids have made a huge difference in my everyday life. I bought the premium ONE 9 aid in hopes that once covid clears it'll help me in restaurants and noisy places since that is where I struggle the most. But for now, just wearing them around the home, on walks (I can hear the birds!) has been a huge improvement and frankly, blessing in my life. I have no complaints with the battery life, simply put them in the charger each night and at end of day I still have more than enough charge left for several more hours of use. I understand these li-ion batteries do go down over time, so maybe that won't last, but for now I'm one happy camper, as that was a big concern. I have friends who own the RESOUND linx model with rechargeable batteries and they have had terrible luck and had to stop using rechargeable batteries altogether. So, glad these are holding up thus far and optimistic they will continue to do so. As another review stated, Bluetooth has issues from time to time, but honestly all of my Bluetooth devices do, from my landscape lighting to Alexa...just goes with the territory for. All in all very satisfied!

Disappointed that the heavily advertised marie receivers will not work for my hearing loss. Overall I am satisfied with my one 9s, regular battery model, but was really looking forward to trying maries. Should be made for clear in adverts that it won't work for severe cases.

I got the new Resound One M&RIE 90 hearing aids and as a first time wearer I love them. Everything sounds very natural and they even do a great job in a noisy environment like a restaurant, where I can hear clearly without a lot of background noise. I definitely give these Resound Hearing Aids a Five Star Plus rating.

5 stars IF they had better feedback suppression. I'm pleased with the hearing aids, but I am displeased that I'm going to have to use standard receivers, not the marie receivers, bc my hearing loss is just past the acceptable threshold to wear the marie receivers without feedback. With maries, just an inordinate amount of whistling, it's too bad, and I hope that one day the maries can handle a more severe hearing loss.

Excellent sound quality and build quality. TV streaming with optional streaming device is excellent. Microphone in ear provides additional sound detail and directionality. No issues with rechargeable batteries. Iphone app with multiple listening programs is very convenient and each program can be adjusted to suit local environment. Covid-19 has greatly restricted social interaction but I am sure performance will be excellent in restaurants, concerts and crowded venues. Due to the products complexity there is a learning curve but well worth the effort. Overall I am extremely pleased with the purchase and highly recommend this product.

Enjoying my ReSound One 9 hearing aids and I can definitely tell that it is easier to hear where sound is coming from, thanks to the M&RIE receivers. A few Bluetooth glitches here and there, losing connection with my iPhone, but I understand all hearing aids have these issues, based on my research.

VERIFIED BUYER | Libertyville, IL ?

I ordered the ReSound One 9R hearing aids which had clearer sound and little background noise. I still felt the clarity was not enough when in a group the streaming to my phone was not so clear. The audiologist increased the clarity to the max and put a different dome or receiver on the hearing aids. This made me feel like there was an echo under some circumstances and like I was wearing ear plugs. My hearing borders on profound loss in some areas and I'm not sure what will be better for me, but I felt that for the money I should be able to hear better and more comfortably.

The sound quality is unbelievable compared to my first pair which my new pair replaced due to having lost one of them. The clarity is unbeatable and they have been extremely comfortable since I picked them up on Dec.21st. I have not had any problems since then. The ease of using my smart phone with the new pair has been a definite plus.
