H2O Audio TRI RUN

Your runs, rides, and training sessions just got a soundtrack — without sacrificing the awareness that keeps you safe.

The H2O Audio TRI RUN delivers premium bone conduction audio and IPX8 waterproof protection in a lightweight, wrap-around design built specifically for land and water surface sports.

Open-Ear Sound That Keeps You Safe – Bone conduction technology transmits audio through your cheekbones directly to your inner ear, bypassing your ear canals entirely. Your ears stay open, so you hear your music and your surroundings at the same time — cars, trail runners, and your training partners included.

Built to Handle Whatever You Throw at It – IPX8-rated waterproof protection means the TRI RUN survives sweat, rain, surf, and paddle splashes without skipping a beat. The secure wrap-around neckband stays locked in place on tempo runs, technical descents, and everything in between.

Premium Sound, No Compromises – Years of bone conduction engineering and H2O Audio's proprietary acoustics software produce amplified bass and clear audio that outperforms what most athletes expect from open-ear headphones. Stream your playlist over Bluetooth 5.3 from your phone or watch, take calls with the built-in waterproof mic, and stay fully dialed in across every session.

How to Use the H2O Audio TRI RUN

Pair, wear, and go. Connect to your phone, smartwatch, or any Bluetooth-enabled device via Bluetooth 5.3 before your workout. Position the neckband securely behind your head with the bone conduction transducers resting against your cheekbones just in front of your ears — no insertion required. 

Enjoy up to 6 hours of continuous playback per charge. Charge fully before long training days or events.

Pro Tip: For the best sound on the run, make sure the transducers sit flush against your cheekbones. A snug neckband fit dramatically improves bass response and overall audio clarity.
