H2O Audio Tri 2

Manufacturer: H2O Audio

The H2O Audio Tri 2 are neckband-style wireless earbuds built around an open-ear fit, making them a practical option for active use where situational awareness matters. They include wingtip supports for a more secure hold during movement, and the neckband form factor keeps the earbuds tethered without relying on a fully wire-free setup. A noise-canceling microphone is integrated, allowing the headset to handle calls alongside audio playback.

On the technical side, the Tri 2 carries an IPX8 waterproof rating with a depth tolerance of 3.6 meters, which positions it well for aquatic activities. Bluetooth 5.3 handles wireless connectivity with a stated range of up to 10 meters. Battery life is rated at 9 hours, with a full charge taking approximately 2 hours and fast charging supported. The earbuds also feature 8GB of internal storage, stereo speakers, voice prompts, a mute function, and an on-device control panel, rounding out a fairly complete feature set for an active-use audio product.

Pros
  • IPX8 waterproof rating with a depth tolerance of 3.6 meters makes it suitable for swimming and water-based activities
  • 8GB of internal storage allows audio playback without needing a connected device
  • Neckband design with wingtips provides a secure fit during physical activity
  • Fast charging support reduces downtime between uses
  • Includes a noise-canceling microphone for clearer voice communication during calls
  • Battery life of 9 hours offers extended use between charges
Cons
  • Open-ear fit provides no passive noise isolation, leaving the listener fully exposed to ambient sound
  • No active noise cancellation for environments where blocking out external noise would be useful
  • Lacks support for advanced audio codecs such as LDAC, aptX, or AAC, limiting wireless audio quality options
  • Does not support true wireless operation, as a neckband cable connects the two earbuds
  • No wireless charging support, requiring a wired connection every time the battery needs replenishing
  • Bluetooth range is limited to 10 meters, restricting movement away from the source device
Who is this for?

This product is well-matched for users who engage in water-based activities such as swimming or open-water training, given its IPX8 rating and 3.6-meter depth tolerance. The 8GB of internal storage makes it a practical choice for those who want to listen to music without carrying a separate device or staying within Bluetooth range, which is particularly useful in pool environments where a phone cannot be nearby. The neckband form factor with wingtips and an open-ear fit also suits active users who need a secure hold without sacrificing awareness of their surroundings.

Who is this NOT for?

Users who prioritize high-fidelity wireless audio will find this product limiting, as it lacks support for advanced codecs such as LDAC, aptX, or AAC, which restricts the quality of streamed audio. It is equally unsuitable for those who need noise isolation or active noise cancellation — the open-ear design and absence of any passive or active noise blocking make it a poor fit for commuting, office use, or any environment where external sound interference is a concern. Additionally, users who prefer a fully wire-free experience will be put off by the neckband cable connecting the two earbuds.

Final Verdict

The H2O Audio Tri 2 is a purpose-built neckband earbud designed around one clear strength: waterproof durability with an IPX8 rating and 3.6-meter depth tolerance, paired with 8GB of internal storage that frees the user from needing a nearby device during aquatic activities. These two attributes define its appeal and anchor its value for swimmers and water-sport enthusiasts who need reliable audio in conditions where most earbuds simply cannot function. Outside of that context, the lack of advanced codec support, no noise isolation, and a tethered neckband design narrow its appeal considerably for general everyday use. For its intended audience, however, the Tri 2 delivers a focused and well-considered feature set that prioritizes practicality in the water over broad versatility on land.
