OTO are a pair of headphones that can compensate for hearing losses and sensitivities by adjusting the audio playback to the listener’s hearing.

Upon set-up, the listener undergoes a hearing test. The supporting app maps out their hearing spectrum, and audio playback is adjusted to a personalised hearing profile. Playback is further optimised depending on the type of listening through two modes - Immersive Mode is designed for maximum engagement with the audio, whereas Speech Mode looks at amplifying voices for easier clarification of spoken word during video calls and podcasts.
