H2O Audio Sonar 2 PRO: Waterproof Bone Conduction Headphones for Swimming with MP3 Player

Open-Ear Sound Underwater with the Sonar 2 PRO

H2O Audio's Sonar 2 PRO brings bone conduction into the pool, delivering clear audio without covering your ears. The open-ear design lets you keep an eye on lane lines, coaches, and your surroundings while you swim. With an IPX8 rating, you can swim with confidence down to 12 feet for pool or open-water sessions.

The device features a streamlined profile that is 40 percent smaller and thinner than previous models, reducing drag and allowing it to sit comfortably under most swim caps. A removable goggle clip helps secure the headset during laps or drills.

Your Music Your Swim

With 8 GB of built in storage you can carry up to 2,000 songs offline. It supports iTunes and MP3 formats, and you can drag and drop music from your computer for phone-free workouts in the water.

• Playlist plus recording lets you save Bluetooth audio to the headset for offline playback during drills
• The included H2O Audio Pro app makes it easy to create and organize playlists on iOS and Android

Wireless and Water Resistant

Bluetooth 5.3 delivers wireless streaming to phones, smartwatches, or computers. Expect up to 30 feet of range on land and about 4 inches underwater, making it practical when the device is mounted near the goggles.

• Enjoy up to 9 hours of Bluetooth playback or 6 hours in MP3 mode on a full charge
• The complete package includes the headset, protective case, USB charging cable, swim earplugs, and a user guide for quick setup

Designed for Serious Swimmers

Engineered for competitive swimmers and triathletes, the Sonar 2 PRO emphasizes reliable sound delivery, easy operation with wet hands, and a drag-friendly design that supports intense training and racing environments.
