H2O Audio TRI Run review

TRI Run is H2O Audio's bone conduction headphone aimed squarely at this list's audience. The company says it is designed for running and road or trail cycling, with a wraparound neckband that stays put and ears left open to traffic, conversation and the road around you. It streams over Bluetooth from a phone or smartwatch, takes calls through an integrated waterproof microphone, and uses physical buttons placed for use mid-stride. The IPX8 rating covers sweat, rain and hard conditions, though H2O Audio notes it is not meant for swimming because Bluetooth does not carry underwater; its TRI 2 and TRI Ultra models cover that. Battery life is up to 6 hours with magnetic USB charging, and LED indicators plus voice prompts report battery status. A safety leash comes in the box. H2O Audio does not publish a weight on the product page. At $99.99, it is a straightforward pick that costs about the same as Mojawa Run Plus, which offers more features.
