For Coaches
Revolutionize Swim Training with Waterproof Audio
Zygo was built for swim coaches who need a better way to communicate with swimmers in the water. With waterproof audio technology, coaches can deliver live instruction, technique cues, safety alerts, and real-time swim feedback while athletes are actively training.
We created Zygo because traditional coaching methods often stop at the pool deck. After months of trying to adapt existing technology for underwater communication, we realized the ideal solution did not exist. That’s how Zygo was born: a swim coaching system designed to bring live audio, real-time feedback, and underwater communication into the pool.
Live One-Way Communication
With Zygo waterproof swimming headphones, coaches can communicate with their team or students underwater during drills, laps, and swim training sessions. The handheld transmitter doubles as a walkie-talkie with a built-in push-to-talk mic, allowing a coach, trainer, or poolside partner to deliver real-time coaching cues or safety alerts directly to the swimmer.
This live one-way communication helps coaches correct technique in the moment, guide pacing, support structured workouts, and keep swimmers more connected during training.

Fits comfortably with Goggles and Swim Cap
With our Flex Fit technology, a one size fits all headset will work with any swimmer's head dimensions and stay on securely. We guarantee it.

Zygo for Swim Coaches
How can swim coaches use Zygo during training?
Swim coaches can use Zygo to deliver live one-way audio cues, technique corrections, pacing guidance, and safety alerts while swimmers are in the water. This allows coaches to provide feedback during drills and laps instead of waiting until the swimmer returns to the wall.
Does Zygo allow real-time underwater communication?
Yes. Zygo is designed for real-time underwater communication through live one-way audio. The handheld transmitter includes a push-to-talk mic, allowing coaches or poolside partners to speak directly to swimmers wearing Zygo waterproof swimming headphones.
Can Zygo help with swim technique correction?
Yes. Zygo can help coaches correct swim technique in the moment by delivering live feedback while the swimmer is actively training. This can be useful for stroke timing, breathing cues, body position, pacing, and drill instruction.
Is Zygo useful for swim teams and private coaching?
Yes. Zygo can be used by swim coaches, trainers, instructors, and teams that want a better way to communicate during pool workouts. It is helpful for private lessons, team practices, technique sessions, and structured swim training.
What makes Zygo different from traditional swim coaching?
Traditional swim coaching often requires swimmers to stop at the wall to receive feedback. Zygo allows coaches to communicate while the swimmer is still moving, helping make feedback more immediate, clear, and actionable during training.
