ORII uses bone conduction, a technology that has been used in medical-grade devices for decades. ORII uses bone conduction transducers that convert electrical signals into vibrations that travel through bone and directly into the inner ear, bypassing the eardrums. This is why bone conduction, when applied properly, can offer superior audio quality even in noisy environments.

The magic of bone conduction is that you can hear it loud and clear, with minimal audibility for the people around you But many bone conduction products suffer from sound leakage, meaning that people nearby can hear what you can hear through your bone conduction device. This is often because they use large actuators at high power output, and there’s always a trade-off between how much power is used to create audio clarity and the amount of sound leakage generated.
