No Need To Shout Anymore, The Swimmers Hear You Anyway

SONR is a wearable radio receiver for swimmers, which allows the coach to improve their technique, during the training even when the swimmer's head is underwater. Shaped as a disc, it is located under the swimming cap to hear the voice of the coach.

Thanks to its sleek and lightweight design SONR does not provoke any discomfort. After just a few minutes of wearing, swimmers forget about the receiver's presence and fully focus on the training, with the coach available to guide them.
