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.

Pros highlights

  • 4.9
    14 reviews strong consensus
    Water/sweat resistance rating: 4.9, 14 reviews, strong consensus
    Water readiness is the strongest consensus area, with reviewers repeatedly praising pool, underwater, and waterproof performance.
  • 3.7
    12 reviews low consensus
    Offline playback and onboard storage: 3.7, 12 reviews, low consensus
    Offline playback is the product's defining advantage for swimming, but Playlist+ recording and syncing can be cumbersome or unreliable.
  • 3.5
    12 reviews low consensus
    Sound quality: 3.5, 12 reviews, low consensus
    Reviewer opinion is split by use case: underwater and swim use often sounds good or even impressive, while several reviewers criticize above-water sound as tinny, muddy, or below regular earbuds.
  • 3.5
    12 reviews moderate consensus
    Value for money: 3.5, 12 reviews, moderate consensus
    Value depends heavily on the use case: swimmers often get enough benefit, while land users and audio-focused buyers face better-value alternatives.
  • 4.0
    11 reviews strong consensus
    Battery: 4.0, 11 reviews, strong consensus
    Battery life is mostly good for workouts and swims, though one review found real-world drain below the stated claim.
  • 4.3
    10 reviews moderate consensus
    Stability: 4.3, 10 reviews, moderate consensus
    Stability is a major strength in water and workouts, although one reviewer with fit issues felt less secure while running.

Cons highlights

  • 3.0
    11 reviews low consensus
    Bass performance: 3.0, 11 reviews, low consensus
    Bass is highly inconsistent: some reviews praise punch or improved bass in water, while others say land playback lacks low-end impact or becomes woolly and hollow.
  • 3.0
    11 reviews low consensus
    Button control usability: 3.0, 11 reviews, low consensus
    Controls are divisive: some reviewers found them reachable or simple, while many criticized stiff buttons, accidental presses, and unreliable secondary commands.
  • 3.1
    9 reviews low consensus
    Software/setup simplicity: 3.1, 9 reviews, low consensus
    Setup is mixed: drag-and-drop loading can be easy, but Playlist+, app handling, and troubleshooting are often described as clumsy or time-consuming.
  • 3.0
    8 reviews moderate consensus
    Treble clarity: 3.0, 8 reviews, moderate consensus
    Treble is serviceable but not consistently crisp; reviewers mention rolled-off, grainy, or missing high-end detail, with a few brighter elements coming through well.
  • 3.0
    8 reviews moderate consensus
    Volume output: 3.0, 8 reviews, moderate consensus
    Volume is adequate for some voices and workouts, but multiple reviewers had to raise it high, noticed vibration, or found volume changes distracting in water.
  • 2.9
    7 reviews low consensus
    Bluetooth: 2.9, 7 reviews, low consensus
    Bluetooth experiences vary sharply: pairing can be easy on phones and laptops, but underwater use, stutters, random disconnections, and clumsy setup hurt reliability.

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.
