Customer Reviews
Headphones are insane. Coach let you know in advance about the upcoming set — it’s super easy to get the best takeoff spot faster than anyone else. And if you’ve got a good coach, you’ll surf more than anyone. Highly recommend.

Very comfortable headphones. They stayed on almost the entire session, and even when they did come off, it was easy to put them back on since they’re attached with a leash. They’re also barely noticeable on the head. During breaks between sets, the coach played music — it felt great waiting for the next wave with music.

Very fast communication with the surfer — he hears everything clearly with no delays. I can give real-time commands and then provide feedback after each ride. It’s the perfect solution for student progression.
