The H2O Audio Sonar 2 Pro

The H2O Audio Sonar 2 Pro is a game-changer for swimmers, combining crystal-clear underwater sound, a secure fit, and unmatched versatility in one sleek, bone-conduction headset.

If you’ve ever wished your pool sessions came with a soundtrack, the Sonar 2 Pro delivers in spades. Designed specifically for aquatic athletes, this waterproof marvel uses bone conduction technology to transmit sound through your cheekbones, keeping your ears open and free from waterlogged distortion. That means no more muffled music or earbuds slipping mid-lap, just pure, uninterrupted audio while you swim, train, or float away to your favourite playlist.

What sets the Sonar 2 Pro apart is its dual-mode versatility. Underwater, you’ll rely on the built-in 32GB MP3 player, which holds up to 8,000 songs, ideal for long workouts or open water swims where Bluetooth simply won’t reach. Above the surface, Bluetooth 5.3 connectivity kicks in, letting you stream from your phone or smartwatch with ease. Whether you’re transitioning from pool to pavement or just want one headset for all your sports, this device adapts effortlessly.

The IPX8 waterproof rating means it’s submersible up to 3.6 metres, and the slim, ergonomic design clips securely to your goggle straps for minimal drag and maximum comfort. Reviewers consistently praise its sound clarity, even underwater, and its ability to stay put during vigorous movement. It’s a standout choice for triathletes, lap swimmers, and anyone who wants to make their time in the water more immersive.

As one reviewer put it: “H2O Audio has nailed the balance between performance and practicality. The Sonar 2 Pro is the headset swimmers have been waiting for.”

Whether you’re chasing a personal best or just want to enjoy a podcast while you paddle, the Sonar 2 Pro makes every stroke more enjoyable. It’s not just waterproof, it’s swim-proof, sweat-proof, and ready to soundtrack your entire workout.
