About ReSound LiNX Quattro
ReSound LiNX Quattro is GN Hearing’s top-of-the line premium hearing aid, the next generation beyond the earlier ReSound LiNX 3D product family. Powered by a new chip platform, it offers including improved sound quality, rechargeability, 2.4 GHz connectivity, and remote fine-tuning.
Utilizing ReSound “Smart Hearing” sound processing technology, LiNX Quattro has an extended dynamic range and improved frequency response. It also utilizes a new radio featuring less lag time in streaming and stronger wireless signal strength for enhanced ear-to-ear performance and localization of sound.
The new chip platform enables advanced speech processing that dramatically improves speech understanding in background noise. Released in 2018, it has twice the memory, 100% more speed, 30% more computing power and a new wireless radio that requires 20% less power to stream sound than ReSound’s previous platform.
And a rechargeable option provides more than a full day of power, even when streaming phone calls, TV and music, with a portable charging case small enough to fit into a handbag or pocket.
Direct streaming from Android phones
ReSound, which was the first hearing aid brand to offer Made-for-iPhone compatibility, got more attention in September 2019 for making the LiNX Quattro the first hearing aid to provide support for direct wireless audio streaming from Android devices. When Google released an update to the Android 10 operating system, Google’s Pixel smartphones became be the first Android phones to support direct streaming to hearing aids.
The streaming specification is also open source. ReSound says to expect other manufacturers of hearing aids and Android devices to offer direct audio streaming to the LiNX Quattro hearing aids “in the near future.”
2.4 GHz wireless streaming accessories
Prior to its iPhone hearing aids, ReSound was a pioneer in 2.4 GHz wireless technology streaming solutions. Among other things, ReSound wireless accessories were the first to eliminate cumbersome "neck loops" that had been required to transmit audio signals to hearing aids.
Now ReSound offers a complete range of 2.4 GHz wireless streaming accessories for the LiNX Quattro hearing aids to complement its Made-for-iPhone and Android technologies. Streaming accessories include a remote microphone and wireless streaming of TV audio.
“The best smartphone app in the industry”
Hearing Tracker included ReSound LiNX Quattro on our list of “Best Hearing Aids in 2019.” In addition to noting its direct Android and iPhone streaming capability, the review highlighted the integrated ReSound Smart app:
It also has the best smartphone app in the industry. It allows you to make all kinds of adjustments to your program settings and even allows you to receive remote adjustments from your hearing care professional.
The redesigned app features one-tap access to most important functions, including program changes, program favorites, and sound enhancer adjustments.
Two models of the ReSound LiNX Quattro are available.
- The ReSound LiNX Quattro RIE 61 a receiver-in-the-canal (RIC) hearing aid with a push button for program control and volume control, water resistant coating and moisture protection rating of IP58, and rechargeable batteries.
- The ReSound LiNX Quattro RIE 62 is a RIC with a telecoil, a dedicated volume control, a push button for program control and volume control, and water-resistant coating. It uses size-13 hearing aid batteries
And finally, custom-crafted versions of LiNX Quattro hearing aids are also available. In August 2019 ReSound introduced a portfolio of in-the-ear custom hearing aids based on the new technology in the LiNX Quattro hearing aids.

ReSound LiNX Quattro Reviews
Hearing aid reviews are fundamentally different from reviews for most other consumer electronic products. The reason is because individual factors, like degree of hearing loss, have a profound effect one's success and overall satisfaction with the product. When purchasing a hearing aid, you'll need to consider more than just your hearing outcome ... Continue readingWrite a Review

Hearing Tracker uses a ten-question survey to assess consumer feedback on hearing aids. The percentage bars below reflect the average ratings provided per question, averaged across all hearing aids belonging to this family of devices.
Note: Original answers provided in star rating format.
I bought the LinX at the end of 2018 and after six months the problems started. When listening to music and touching the hearing aid with my hand, or correcting my glasses, then you touch one of the devices and it just switched off. Music needs to be restarted. A repair was done under warranty. But even after this, the problems persisted. De devices were sent to the workshop twice for repairs. At the end of 2021, I received completely new hearing devices but had to pay 80 euros in administrative costs. But again problems after half a year, now this summer the Bluetooth connection between smartphone and hearing aids just breaks down, several times per day. Have to restart the phone and that is quite normal according to ReSound. To me, this is just incompetence and I seem to be the only one. Sorry, but if you pay almost 5,000 euros for hearing aids, then I can expect top quality and not arrogance from the service department which tells me not to whine. Listening to a concert via the Music program position in the app is no fun either because the volume automatically goes down and then comes back up at a certain point. I have no problems with the app on my tablet, both Apple products. I guess GN-Hearing just can't seem to configure Apple updates correctly with the Smart 3D app. No more Re-Sound hearing aids for me!
Been a long time Resound user, finally bought a pair from Costco. Worst decision of my hearing aid life!!!
Nothing but problems don't hold a charge, turns off and back on without warning, one or the other stops functioning then starts.....lost program, and they take over your phone because they want you to use their location program......worst decision! I have worn Resound for 20 years, never never never again
Sound not clear... sounds like everyone is gargling
I'm assuming that the reason that these aids quality is so devilishly inconsistent is that they might not have participated in "quality assurance" checks since they were sold to the Veterans Administration - U. S. Government. They never worked very well, but better than nothing, until they were about a year old when they were returned to a "depot" in Colorado to be rebuilt. Since then they are now "in a high pitched feedback mode" constantly. I quit wearing the left one. I refuse to try to deal with the local VA Clinic anymore. Hope yours are better than these!
The bloody ear pieces are to small with glasses. I have trouble keeping them above my ears.
I thought they were fantastic until I did the upgrade and now I get a high frequency noise in the left ear and right here when I put them in the left ear cut out quite a bit.
I recently upgraded from the Linx3D to the Quattro's. The Quattro's feel like a refined version of the Linx3D but with some significant refinements. Bluetooth is much more stable and the dynamic range and sound quality (especially music and speech in noise) is improved. The byluetooth connectivity is flawless and the rechargeable batteries are a major upgrade. I'm a heavy streaming user (online meetings for work) and I my batteries rarely go below 50% after a day of heavy usage. I'm also pleased to be finally free of battery anxiety (I don't have to stash extra batteries everywhere). Great upgrade and very pleased with these hearing aids.
I have the Resound Linx Quattro RIC 9R hearing aids. They're my first hearing aids so I'm not sure how they should be rated compared to others.
Likes: The rechargeable batteries are great. I charge overnight but have gone two days without recharging a few times. The charger is very well designed.
Dislikes: Let me preface this by admitting that I am fussy.
The app (Android) is fairly limited. The custom tailoring you can do is limited and doesn't work all that well. The app doesn't stay connected so I never know what mode they're in and the location control doesn't work.
Overall I am glad I got the to of the line 9s but only because I know it doesn't get any better than this. I think the cheapest ones (the 5s?) would have been just as functional.
Having switched from Widex Evoke, the Quattros are significantly better with noisy situations and for me, have much better bass response on closed moulds, with severe SNR (signal to noise) with speech (>14dB).
The noise reduction and control over this is amazing; car journeys are quite difficult but with this control it makes things much much easier. Loud sudden noise is dealt with well, and expansion works as expected in silence/near silence. I certainly seem to be asking for people to repeat considerably less in many situations. AGC is extremely good and does not seem to pulse anywhere near as much as previous manufacturers.
Battery life is fantastic for streaming >50% of the day every day. Minimum has been at least 10 days with 16 hours per day.
Streaming is very good and considerably more responsive with less of a connection delay (almost instant) with iOS. From the TV streamer 2, the timeout for silence is a respectable 5 minutes, rather than 30 seconds for Widex TV PLAY. One of the reasons I moved away from Widex.
The Multi-Mic is significantly better and the sound is very very clear. I do have the DAI receiver for Roger accessories but find that because the Multi-Mic does not require a connection dongle/lanyard, it's my default preference for a lot of situations. It's also very useful not to need the DAI receiver near my head like Widex FM-DEX, I can place it several metres away to help with a distant Roger microphone.
I'm really happy with them and will be keeping.
Resound is a heartless predator of the hearing impaired, usually the elderly. When the hearing aids work, they are fine, but when they malfunction it is virtually impossible to reach the company in order to get help. Since the salesman I bought them from was incompetent, and a liar besides ,I sought help from Resound. Their way out (if you are willing to listen to raucous screeching while on hold) is to refer you back to the salesman . . . an endless loop of frustration.
Most users will find the complex technology of these instruments too confusing to benefit from their potential versatility, especially if you have accessories like a remote and/or an external mini mic. When they malfunction . . . and they probably will . . . you will be unable to troubleshoot the solution yourself and Resound will pass the buck to the salesman. . . . and you will be cut off from audible communication until you find a solution . . . if you ever do.
