H2O Audio TRI 2 PRO Headphones Review
Bottom Line
Choose the TRI 2 PRO if swimming audio, IPX8 waterproofing, and onboard music matter most. Skip it for land workouts if you need rich bass, crisp vocals, easy controls, or simple playlist loading.
Best for
Best for swimmers, triathletes, and pool users who want music or podcasts without relying on Bluetooth underwater. It also suits athletes who prioritize open-ear awareness and comfort over hi-fi sound.
Not for
Not for buyers who want rich land-based audio, strong bass, easy track control, or a simple streaming-style workflow. Runners and gym users who do not need underwater playback are repeatedly pointed toward alternatives.
Verdict
Reviewers consistently frame the H2O Audio TRI 2 PRO as a specialist swim headset rather than a general-purpose sports headphone. Its strongest case is practical: secure fit in water, very high waterproof confidence, onboard storage, and Playlist+ make pool sessions possible without a phone or Bluetooth signal. The tradeoff is that the same bone-conduction design and offline workflow frustrate some reviewers on land, where bass, clarity, and maximum-volume behavior often fall short of regular earbuds or rival open-ear options. Controls and setup split opinions too, ranging from simple and tactile to stiff, finicky, or time-consuming.

FAQ
Does the H2O Audio TRI 2 PRO work underwater?
Yes. Reviewers repeatedly report that it works in the pool and underwater, with onboard memory solving the problem that Bluetooth does not work reliably when submerged.
Is the sound quality good?
It depends on the setting. Several reviewers liked the underwater sound, but many found above-water audio thin, muddy, bass-light, or weaker than regular earbuds and some rival open-ear options.
How comfortable is it for workouts?
Most reviewers found it lightweight, comfortable, and stable for swimming or exercise. The main fit caveat is sizing: a few reviewers with smaller heads or fit gaps found it less secure or slightly awkward.
Is Playlist+ easy to use?
Playlist+ is useful because it can put streaming audio onto the headset for offline swimming, but reviewers often describe the recording process as slow, clumsy, archaic, or requiring patience.
Can it replace everyday earbuds?
The review evidence says it is better treated as a specialist swim headset. For everyday land workouts, critics point to weaker sound, finicky controls, and better-value alternatives.
How is battery life?
Battery life is generally viewed as good enough for workouts and swims. Most reviewers report solid results, though at least one found real-world drain lower than the stated figure.
