Clearer sounds

With the highest input dynamic range on the market today, ReSound LiNX Quattro leverages the full range of the MEMs microphone allowing sound to be passed to our amplifier without being altered. Therefore, sound is processed in a cleaner way - free of distortion.

This ReSound LiNX Quattro platform is phenomenal, and our patients are SO HAPPY. I keep hearing with every fit, “I’ve never heard like this before.”, “These are the best hearing aids I’ve ever had.”, “I can’t believe how much better I’m hearing.”

Fuller sounds

An extended bandwidth to 9.5 kHz means patients will hear a larger range of sounds and will have access to nuances in tones that were previously unavailable to them.

I can honestly say in the last 5 years of practicing audiology I have never had patients react so positively towards the sound quality of a device on the day of their fitting. It is really nice to hear these comments and how satisfied people are.

Richer experience

With clearer and fuller sounds coupled with a new radio for improved ear-to-ear performance and decreased lag time in streaming, patients will receive the most brilliant sound experience yet.

I streamed with them for about 5 hours straight on a drive to New Jersey plus maybe two more hours sporadically, and then was also up and wearing them at 6 a.m. and they were still going at 1 a.m. when I finally took them off! That's 19 hours of use with maybe seven hours of streaming. I'm impressed.

I was also impressed with the sound quality. After putting on and programming the ReSound LiNX Quattros, my assistant came into my office and I was astounded at the sound of the DOORKNOB TURNING! It wasn't louder, just crisper. As was paper, and speech. Went out to a comedy club that night with three other people, never missed a word during the drive down there nor during the conversations in the club after the show. Like I said, I am impressed.

Exceptional streaming

With ReSound LiNX Quattro, your patients can stream directly from both iOS® and Android™* devices without an intermediate device. With clearer, fuller, richer sounds, they can answer phone calls with confidence in any environment and enjoy the finer details of TV and music.

*Full streaming compatibility with Android devices requires minimum Android v10 and Bluetooth 5.0 and that functionality has been enabled by the phone manufacturer and service carrier. Accordingly, the compatibility information provided should be used for reference only. Although GN strives to achieve seamless device compatibilities, GN cannot guarantee full compatibility with all Android devices.
