How to wear it?

Thanks to its sleek and lightweight design, SONR Receiver ensures comfortable wearing.

After just a few minutes, swimmers forget about its presence, fully focusing on the training and the coach’s instructions.

How boneconduction works?

We can hear sound in two ways: through air and bone conduction.

Air conduction is how we hear most of the time. Our eardrums convert sound waves into vibrations sending them to the cochlea.

Bone conduction is when sound is delivered directly to the inner ear through the bones of the skull, bypassing the eardrums.
