The Ear-Defense AirTips redefine hearing protection & hearing enhancement developed from a multi-patented technology that will transform the traditional hearing protection industry.

With support from the National Science Foundation and the National Institutes of Health, our technology partner, Asius Technologies developed a product that provides unequaled sound attenuation. Ear-Defense represents the first true approach to hearing protection in a comfortable design, fatigue free and customizes to every ear by inflating a specialized ear tip. A universal fit protects users from damaging sound levels while balancing the audio spectrum and reduces sound pressure versus traditional products that only muffle the sound.
