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.
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.
