H2O Audio TRI 2: Bone Conduction Open-Ear Headphones, Bluetooth 5.3, MP3 Mode, 8GB, 8.5h Battery

Meet the H2O Audio TRI 2

The TRI 2 continues H2O Audio’s commitment to clarity, comfort, and durability with an open-ear design that sits just outside the ear canal. Its soft silicone finish feels gentle against skin, making it suitable for long workouts, commutes, and water-adjacent activities. A rugged hard-shell case guards the hardware, while a practical layout helps you stay in control during any motion-packed moment.

Designed for real-life movement

On land, you can stream music, podcasts, or take calls thanks to Bluetooth 5.3. When you switch to underwater use, MP3 mode lets you tap into built-in memory for uninterrupted playback without relying on wireless signals. The result is a seamless transition between environments without sacrificing awareness or safety.

• On-land listening with wireless streaming and accessible controls for runs and rides
• Underwater playback via MP3 mode with built-in memory for pool and water workouts

Power, memory, and portability

Expect about 8.5 hours of mixed-use playback, with separate estimates for Bluetooth streaming and MP3 playback. The 8GB memory stores roughly 2000 songs, translating to as much as 130 hours of listening under the right formats. This setup supports a wide range of audio styles, from upbeat tracks to helpful podcasts.

• Powerful 8.5 hours of mixed-use battery life for longer sessions
• 8GB memory for offline listening and large music libraries

Smart design and dependable protection

Intuitive button placement makes volume adjustments, track changes, and call answers straightforward even during intense activity. The included hard-shell case protects the unit from knocks and drops, and H2O Audio backs the product with the Go Beyond Promise for up to one year, reinforcing peace of mind with everyday wear.
