The basic functionality of asEars is the same as that of CROS hearing aids: picks up sound from the angle you cannot listen to well, then transmit it to the other side.

asEars uses dual microphones placed on the rim to picks up sound selectively from the deaf side. Advanced digital sound processing is done completely inside the device, and the processed sound is transmitted by a bone conduction speaker placed near the functioning ear.
