Traditional hearing aids amplify sound through a speaker. But, tiny speakers can only amplify a limited bandwidth of sound before the sound quality deteriorates. Think of how much better music sounds through a theater surround sound system versus tiny earbuds. Conventional hearing aids try to compensate for these limitations through complex algorithms, but those can only go so far. That’s why Earlens decided to change the game.

With normal hearing, sound enters the ear canal and vibrates the eardrum, which activates the natural hearing system. Instead of using a speaker to amplify waves, Earlens uses a custom Lens to gently move the eardrum, just like in normal hearing. The result is rich, natural sound with crisp highs and full lows across a broader bandwidth—including the higher frequencies that contribute to speech clarity and understanding.
