H2O Audio TRI 2 Blue – Multi-Sport Waterproof Bone Conduction Headphones with MP3 Player & Charging Case

Overview

The H2O Audio TRI 2 Blue redefines listening during water and land workouts. These multi-sport headphones use open-ear bone conduction to deliver sound while keeping your ears free and awareness intact. The TRI 2 bundle includes a protective hardshell charging case that can recharge the headphones twice, helping you stay powered through longer sessions without interruption.

Durability and Waterproofing

Built for wet environments, the headphones carry an IPX8 rating, with submersion capability up to 12 feet (3.6 meters). The secure neckband and tailored fit are well suited for laps, trail runs, splashy rides, and other active pursuits. Earplugs are included for swimming to reduce water noise and help you focus on your music and pace.

Sound, Design, and Comfort

The open-ear bone conduction speakers are slimmer by about 5 mm compared with earlier TRI models, delivering clear sound with minimal pressure on the ears. The design supports extended wear during workouts, while the neckband helps keep the unit stable on fast moves. Real-life use often involves quick transitions between land and water, where this fit can make a difference.

Music Options and Connectivity

• Built-in MP3 player with 8 GB memory holds thousands of tracks and supports common formats including .M4A.
• Bluetooth v5.3 enables wireless streaming from phones, tablets, or smartwatches when you are above water.

Note: Bluetooth does not work underwater. To listen while submerged, switch to MP3 or Playlist+ mode for underwater playback.

Battery Life and Charging

• Between 6 and 9 hours of playtime depending on usage and volume.
• Charging time around 2 hours; the included charging case can fully recharge TRI 2 twice.

Use Case Scenarios

Whether you are swimming laps, cycling along coastlines, or running intervals, the TRI 2 is designed for your sport and your music. The open-ear design helps you stay aware of your surroundings while enjoying your soundtrack, creating a balanced training experience.
