H2O Audio SONAR 2 PRO – Waterproof Headphones with MP3 and Bluetooth

Experience the freedom of swimming with music — without any compromises. The H2O Audio SONAR 2 PRO enhances the award-winning technology of the original SONAR: it's 40% smaller, lighter, and more comfortable, so you can barely feel you're wearing them.

Combining bone conduction technology with IPX8 waterproofing and an 8GB built-in music storage, you enjoy crystal-clear sound underwater without needing your phone.

Why You'll Love SONAR 2 PRO:

Compact and Lightweight Design: 40% smaller than its predecessor — fits snugly without discomfort.
Bone Conduction Sound: Experience sound through your cheekbones, allowing you to stay aware of your surroundings.
Built-in MP3 Player: Store up to 8GB of music or podcasts directly on the device.
Bluetooth Connectivity: Stream music from your smartwatch or phone (within short range).
Long Battery Life: Provides up to 10 hours of playtime, perfect for multiple swim sessions.
100% Waterproof (IPX8): Tested at depths of up to 3 meters, specifically designed for swimming, not just sweating.
Easy Controls: Large, tactile buttons make it simple to manage your music even with wet fingers.

Everything You Need in One Device

With both Bluetooth and MP3 player integration, SONAR 2 PRO lets you choose what works best for you. Want music directly from your smartwatch? Simply connect via Bluetooth and attach the watch to your swim goggles. Prefer the freedom of no signal restrictions? Use the PLAYLIST+ feature to save music locally on the device.

Underwater, the Bluetooth range is only a few centimeters, so we recommend using the built-in memory for the best experience.

Compatible with H2O Audio App

Manage your music, create folders, and update software directly from the free H2O Audio PRO App (available for iOS and Android).

Questions & answers

Can I use the SONAR 2 PRO entirely without a phone?

Yes, the SONAR 2 PRO features a built-in MP3 player with 8GB of storage, so you can swim completely hands-free—no phone or watch needed.
How does bone conduction technology work?

Bone conduction technology delivers sound through your cheekbones instead of your ear canal, offering clear audio while keeping your ears open.
Is the Bluetooth connection stable underwater?

Bluetooth provides stable performance underwater only if your device is very close (such as attached to your swim goggles). For greater range, we recommend using the MP3 mode.
How do I transfer music to the MP3 player?

Connect the device to your computer via USB to transfer music files directly—both MP3 and Apple iTunes formats (.m4a) are supported.
How long does the battery last on a full charge?

The battery offers up to 10 hours of playtime per full charge, depending on volume and usage.
Can I use the SONAR 2 PRO in seawater or a pool?

Yes, it's fully waterproof with IPX8 certification and is suitable for both pool and open water swimming—simply rinse after use to prolong its lifespan.

Maintenance

Rinse the unit with fresh water after use in the pool or sea to extend its lifespan.
Ensure that the charging port is completely dry before charging.
Store in the provided case when not in use to protect against scratches and dust.
