Shout-free training Meet SONR, an innovative swim coach communicator for real-time communication that helps save the coach's voice during swim training. The coach talks into the radio transmitter, and the swimmer receives precise instructions.
About the technology The bone-conduction technology allows athletes to hear the coach's voice even underwater, conducting the sound directly to the inner ear. SONR receivers act as waterproof headphones for swimming and help swimmers follow the coach’s instructions in real-time.
Most Effective Swim Training Swim training equipment and swimming accessories are ideal coach gifts. Real-time coaching with SONR overcomes the main obstacle in all water sports - the lack of real-time communication. SONR bone conduction headphones might also be considered one of the best devices for stroke correction, swim lap counter, and other guidance. Thanks to constant feedback, the athletes correct their movements, learn faster, and achieve their goals quicker.
Unique SONR Features No earbuds or Bluetooth, SONR radio transmitter helps the coach give the instructions right when it's needed. Swim coaches can use an additional headset with microphone to provide instructions hands-free. SONR, a wireless headset, can be used in any type of swim training - open water or pool training.
SONR Metronome SONR is not just underwater headphones, it also has a built-in metronome that helps track your tempo and pace.
Individual & Team coaching With SONR waterproof headphones swimming becomes easier! It’s the ideal solution for individual and group sessions. Using SONR, the coach can guide an unlimited number of athletes at the same time, communicating with all of them or dividing them into smaller groups. SONR swimming headphones increase the swim workout efficiency, ensuring real-time corrections and feedback from a coach to swimmers.
Designed for winners Thanks to its sleek, lightweight design and small size, it is convenient to wear SONR for kids and adults, women and men. It can be placed under the swimming cap or on the straps of the swim goggles.
Distance & Depth SONR's receiving distance is up to 984 ft (300 meters) in open water and up to 164ft (50 meters) in the pool, and up to 3 ft (1 meter) in depth. SONR receiver and radio transmitter are rechargeable. We also recommend using earplugs for even better sound clarity.
