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.

SONR Receiver can be placed anywhere
on the swimmer's head
under the cap.
Don't like wearing a cap? SONR Receiver can be fixed on your goggles strap.
How bone
conduction 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.

SONR is compact and easy to operate. The sound is clear and it works at a great distance. I want to purchase SONR as early as possible, so I wouldn’t have to raise my voice in a noisy pool anymore.
