Red I want to try that one-button switch during a long training session—Bluetooth for one stretch, a saved playlist for the next.
Nea If I owned a game soundtrack as audio files, I’d like to take it along without my phone. Choosing a few favorite tracks would be a pleasure.
Switch to stored tracks with one button
Both models combine Bluetooth with 8GB of onboard memory. A dedicated Mode button switches between Bluetooth and stored-audio playback with one press, replacing the Play/Pause double-click used on TRI 2.
Music and podcast files you own can be transferred from a computer by dragging and dropping them or using the free H2O SYNC desktop app. Those saved tracks can then play without a phone on the trail or while swimming; underwater playback uses memory, not a live Bluetooth stream.
What the PRO adds for its higher price
At the US official store, TRI ULTRA costs $199.99 and comes in Ocean Blue or Summit White. The black TRI ULTRA PRO costs $249.99 and adds PLAYLIST+, which captures streaming audio as it plays and saves it to the headphones for offline listening, along with support for H2O Audio’s iPhone and Android app.
H2O Audio announced a limited-quantity launch through H2OAudio.com. The manufacturer expects availability at US retailers Amazon and Best Buy in early November.
