Elevate Your Hearing

We develop breakthrough audio technologies for your hearables.

Occlear® Technology

Natural Own Voice Through Occlusion Cancellation

Existing headphones isolate the user from the environment and make their own voice sound boomy and unnatural. This is due to the occlusion effect which attenuates air-conducted sound and amplifies body-conducted sound.

A headphone user who is unhappy with the unnatural sound of their own voice.
A headphone user who enjoys a natural own-voice sound thanks to the Occlear® technology.

Our Occlear® technology eliminates the occlusion effect, allowing hearable users to perceive their own voice and their environment naturally. Occlear® requires no specialized hardware and can directly be deployed to ANC-ready hearables via a firmware update.

Press play and listen to some live audio of Occlear® in action. This real-time recording was captured inside a user’s ear using our portable, battery-powered demonstrator built on top of the Analog Devices ADAU1787 audio codec.

The environment audio features “Swing Theory” by Freedom Trail Studio, used under CC-BY.
