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.

I love the small size, sleek shape and the design of the device. It is comfortable, unnoticeable under the cap and doesn’t add resistance while swimming.

We were very pleased with the SONR system, as it brings communication in swimming to the next level.We plan to utilise this with our open water swimmers, so more information can be provided to the swimmer.
