ReSound LiNX Quattro

Brilliant sound experience

With a high input dynamic range of 116 dB SPL and an extended frequency bandwidth of 9.5 kHZ, the brilliant sound of ReSound LiNX Quattro is beyond compare with:

  • Distortion-free sound processing
  • Access to more tones and nuances of sound
  • Improved ear-to-ear performance

Clearer sounds

With the highest input dynamic range, 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.

Confidence in the finer details

Directional technology

Binaural Directionality III is the latest advancement to help patients hear speech in noisy environments, the most difficult listening situation. Unlike other premium hearing aids, ReSound does not rely solely upon narrow directionality and a strict focus. Binaural Directionality III uses ear-to-ear in a meaningful way to patients the best balance of sounds in front, to the sides and from the back to easily monitor their surroundings for the most natural listening experience.

Spatial Sense

With the advanced performance of the new chip platform, our Spatial Sense feature is now better than ever. More high-frequency cues are available to help your patients localize sounds to the front and back. Spatial Sense can also measure the interaural level difference within less than a 1 dB tolerance. This is crucial because accurate level cues that align with timing cues enhance spatial hearing for the most natural sound quality.

Top-rated sound in blind testing

In blind listening tests, more than 400 hearing care professionals in the United States comparted ReSound LiNX Quattro with other premium hearing technology of their choosing.

ReSound LiNX Quattro received the following results:

  • Significantly better at locating speech in noisy backgrounds
  • 17% better on average at understanding speech from varying locations in noise
  • Significantly better at music sound quality*

Fuller sounds 

A broader frequency response means patients will hear a larger range of sounds and will have access to nuances in tones that were previously unavailable to them.

Sound with virtually no limits

The brand-new chip delivers twice the memory, 100% more speed, 30% more computing power and a new radio with 20% reduced power consumption. Together with an extended dynamic range, improved frequency response, a stronger wireless signal strength for enhanced ear-to-ear performance and localization of sound, ReSound LiNX Quattro delivers our most clear, natural sound yet.

116 dB SPL

The highest input dynamic range and the first hearing aid to utilize the full range of the MEMs microphones means loud inputs are more clear and softer sounds are available with less background noise.


Extended frequency bandwidth provides patients with access to more nuances of sound and allows for better sound balance across frequencies - even when streaming.


New radio with 5 dB improved signal strength enhances ear-to-ear wireless performance, allowing Spatial Sense to sharpen and increase localization cues.


Crisp, clean sounds at any level

With the highest input dynamic range on the market today, 116 dB SPL, softer sounds are audible and clear and loud sounds are distortion free.

Preferred for music listening

ReSound LiNX Quattro is preferred 95% of the time for music listening, compared to other premium hearing aids*.
