ReSound KEY 4 Hearing Aid Features List

ReSound KEY 4 Features List

The ReSound Key 4 represents a comprehensive and cost effective better hearing solution. It offers fantastic high-technology features to the affordably priced hearing aid market. 

The Wind Guard feature utilizes the hearing aid’s dual microphones to recognize the presence of wind (turbulence caused by wind is uniquely identifiable at the microphones), then reduces those turbulent sounds caused by wind to improve the wearer’s listening comfort.

The Impulse Noise Reduction feature reduces the impact of sudden sounds in the environment like hammers, bangs, etc.

Key hearing aids have incorporated Quattro’s premium core sound processing technologies.

The Key 4 (RIE 61) also has the same ergonomic tear-drop design as its predecessor, the Quattro (6th generation premium hearing aid).

The manual switching of volume, programs and streaming can be accomplished via a multifunctional push button.

ReSound Key 4 leverages Natural Directionality to support better hearing in noise by enabling both ears to work together.

ReSound Key 4 provides a focused response in one ear while enabling the wearer to monitor the environment with the other ear. This improves awareness of surroundings and ease of listening without any significant reduction in directional benefit.

ReSound KEY hearing aids do NOT include Sound Shaper (frequency compression), nor Low Frequency Boost technology and are NOT recommended for for severe-to-profound hearing losses.

  1. Beth M. From Charlotte, NC.

    I have been so pleased by HearSource. I had issues with my old hearing aids and after 7 years it was time for new ones. I went to my regular audiologist off and was floored by the price. I was upset at how much they wanted to charge me. I found the same hearing aid here for about 1/2 of what the local office wanted. And I feel the service and support have been better than I ever received locally.
    I appreciate the follow-up and support from Hearsource.

  2. Natalie M. From Elk Grove, CA.

    An excellent hearing aid at a super affordable price. I hear well. They are comfortable. The folks at HearSource are amazing. What more can I say. 5 stars isn’t enough.
