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 superior sound of ReSound LiNX Quattro is beyond compare:

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

Spatial Sense

Fuelled by our latest sophisticated chip platform, the Spatial Sense feature delivers more high-frequency cues to help your clients localise sounds to the front and back of them, giving them a true sense of space in their surroundings. Crucially, Spatial Sense can also measure the interaural level difference within less than a 1 dB tolerance. Accurate level cues align with timing cues to enhance spatial hearing for the most natural sound quality.

Fuller sounds 

A broader frequency response enables users to hear a larger range of sounds. They will have access to nuances in tones that were previously unavailable to them.

Sound with virtually no limits

Our impressive chip platform 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 localisation of sound, ReSound LiNX Quattro delivers the clearest, most natural sound.

116 dB SPL

The highest input dynamic range and the first hearing aid to utilise the full range of the MEMs microphones. Loud imputs are clearer and softer sounds have less background noise.

9.5kHz

The extended frequency bandwidth gives clients access to more nuances of sounds and delivers a greater balance of sound across frequencies, even when streaming.

5dB

The stronger radio signal enhances ear-to-ear performance and works seamlessly with our Spatial Sense feature to sharpen and increase localisation cues.

Crisp, clean sounds at any level

With the highest input dynamic range available, softer sounds are audible and clear and loud sounds are distortion-free.

The images above shows the difference between reduced (left image) and highest range (right image).

Preferred for music listening

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