H2O Audio TRI 2 Multi-Sport Review: Is It Still the Best Waterproof Bone Conduction Headphones in 2026?

If you swim, run, cycle, or train outdoors and want one pair of headphones that can handle all of it, the H2O Audio TRI 2 Multi-Sport is a compelling option. It is not the cheapest sports headphone around, but its combination of IPX8 waterproofing, open-ear bone conduction audio, built-in MP3 storage, and solid sound quality makes it worth considering—especially if you use the MIFECOUPONS discount code to save 20%.

H2O Audio TRI 2 Multi-Sport Review: First Impressions

The first thing that stands out about the TRI 2 Multi-Sport is that it is designed around a very specific problem: listening to music while exercising without worrying about water damage or completely blocking out your surroundings.

Unlike conventional in-ear headphones, the TRI 2 uses bone conduction technology and an open-ear design. This makes it particularly interesting for swimmers and outdoor athletes who want to remain aware of what's happening around them.

On paper, the specifications are impressive. The headphones are rated IPX8 and can be submerged to 12 feet (3.6 meters), while the built-in 8GB MP3 player provides space for up to 2,000 songs or around 130 hours of music. Bluetooth is available for land-based activities, although it does not work underwater, so swimmers need to use MP3 mode in the pool.

After looking at what the TRI 2 is actually designed to do, my verdict is straightforward: yes, the H2O Audio TRI 2 Multi-Sport is worth considering if swimming and water sports are part of your regular routine. For someone who only needs headphones for casual gym sessions or commuting, however, its waterproof capabilities may be more than you really need.

Design & Build Quality

A Secure, Sport-Focused Design

The TRI 2 Multi-Sport has a lightweight open-ear design with a neckband that keeps the headphones securely positioned during activities. The overall shape feels more purpose-built for movement than a standard pair of wireless earbuds.

The updated design also features a softer silicone finish and redesigned button placement. These are small details, but they matter when you're trying to control your music while running, cycling, swimming, or wearing the headphones in wet conditions. H2O Audio says the new bone conduction speakers are also 5mm slimmer than those used in the previous TRI headphones.

One thing to be aware of is the fit. If you're coming from traditional earbuds, the first few uses may feel slightly unusual. The way bone conduction headphones sit against your head is different from simply putting an earbud into your ear, so it can take a little time to get used to the positioning.

Once you understand how the headphones should sit, the secure-fit design makes much more sense. The included swim earplugs are also a useful addition for pool sessions because they help reduce the amount of water noise reaching your ears.

What's Included?

The package includes:

• TRI 2 Multi-Sport headphones

• USB charging cable

• Protective case

• Swim earplugs

• User manual

The inclusion of a protective case and dedicated swim earplugs is a nice touch, especially for people who plan to use the headphones regularly in the water.

Performance Analysis

Sound Quality: Better Than You Might Expect

The biggest surprise in this H2O Audio TRI 2 Multi-Sport review is the sound quality.

Bone conduction headphones traditionally involve some compromises compared with conventional closed-back headphones or high-quality in-ear models. The TRI 2, however, is designed to improve the listening experience with enhanced speakers and acoustics, including a focus on stronger bass response.

In practical terms, the TRI 2 delivers a more enjoyable sound profile than I would expect from a product primarily designed for swimming and multisport use. Music sounds clear enough for workouts, and the open-ear design allows you to maintain awareness of your surroundings during outdoor activities.

The experience is particularly different underwater. This is where the TRI 2's built-in MP3 functionality becomes important.

Bluetooth for Running and Cycling, MP3 for Swimming

One of the most important things to understand before buying the TRI 2 is that Bluetooth does not work underwater.

For running, cycling, and other activities on land, you can connect the headphones to an iPhone, Android phone, or compatible smartwatch via Bluetooth. The headphones use Bluetooth 5.3 and can provide up to around 9 hours of Bluetooth playback.

When you go swimming, you'll need to switch to MP3 mode. The built-in 8GB storage can hold up to approximately 2,000 songs or 130 hours of music, according to H2O Audio. That's plenty of space for most users to create a dedicated swimming playlist without carrying a smartphone into the pool.

This setup is practical, but it does mean you need to think about how you'll use the headphones before jumping into the water. If you're expecting to stream Spotify directly over Bluetooth while swimming, the TRI 2 isn't designed for that. The higher-end TRI 2 PRO is the model that adds the PLAYLIST+ feature for storing streaming music for offline or underwater listening.

Waterproofing: The Real Reason to Buy

Water resistance is where the TRI 2 Multi-Sport really separates itself from ordinary sports headphones.

The headphones carry an IPX8 rating and are designed for submersion up to 12 feet (3.6 meters) for unlimited time. That makes them suitable for swimming and other water-based activities where regular Bluetooth earbuds simply aren't an option.

For swimmers, this is arguably the most important feature. You don't have to worry about keeping your phone poolside and hoping your headphones survive a splash. The TRI 2 is purpose-built for this type of environment.

The same waterproof design also makes the headphones suitable for activities such as paddling and surfing, while the secure fit is intended to keep them in place during active movement.

Battery Life

Battery performance is respectable for a multi-sport headset.

H2O Audio rates the TRI 2 for approximately 9 hours of Bluetooth playback and 6 hours in memory mode, with actual battery life varying depending on usage and volume. Charging takes around two hours.

For most individual workouts, this should be more than enough. However, if you regularly train for long periods or forget to charge your headphones between sessions, you'll want to keep an eye on the battery level.

H2O Audio TRI 2 Multi-Sport Pros & Cons

Is H2O Audio TRI 2 Multi-Sport Worth It?

The answer depends heavily on how you exercise.

If you're a regular swimmer, triathlete, or multisport athlete, the answer is yes. The TRI 2 solves a problem that ordinary wireless earbuds cannot: it lets you listen to music underwater while remaining completely waterproof.

The combination of an IPX8 rating, built-in MP3 player, Bluetooth connectivity for land activities, and open-ear bone conduction technology makes the TRI 2 a versatile option for people who train across different environments.

On the other hand, if you mainly want headphones for walking, commuting, or occasional gym workouts, you may not need to spend this much. A less specialized pair of open-ear or wireless headphones could offer better value for your particular needs.

The other consideration is the learning curve. The first few times you wear the TRI 2, the fit and bone conduction sensation may feel unfamiliar. That's not necessarily a flaw, but it's something to expect if you've only ever used traditional earbuds or over-ear headphones.

Overall, is H2O Audio TRI 2 Multi-Sport worth it? For serious swimmers and multisport users, I think it is. For everyone else, the decision comes down to whether you will actually use its waterproof and underwater MP3 capabilities.

Value for Money: Is the TRI 2 a Good Buy?

At the time of this review, the official H2O Audio product page lists the TRI 2 Multi-Sport at $149.99.

That's not an insignificant amount for a pair of sports headphones, but the price becomes easier to justify when you consider that this is a specialized product built for both land and underwater use. You're essentially getting Bluetooth headphones for running and cycling combined with a waterproof MP3 player designed for swimming.

The value proposition is strongest if you actually use those features. If you swim several times a week, being able to listen to music underwater without carrying a phone can make the price feel much more reasonable.

Final Verdict: H2O Audio TRI 2 Multi-Sport Review Score

The H2O Audio TRI 2 Multi-Sport is a specialized pair of headphones that does one thing particularly well: it makes listening to music during swimming and multisport training genuinely practical.

The IPX8 waterproofing is the standout feature, but the built-in 8GB MP3 player, improved sound quality, secure fit, and Bluetooth connectivity for land-based workouts make it more versatile than a typical waterproof headset.

The main drawbacks are the learning curve of the bone conduction design and the fact that Bluetooth cannot be used underwater. Those limitations are easy to understand once you know how the product works, but they are important to consider before buying.

Overall Rating: 9/10

Best for: Swimmers, triathletes, runners, cyclists, paddlers, and active users who need one pair of headphones for multiple sports.

Worth buying? Yes—especially for regular swimmers and multisport athletes. If you rarely exercise in the water, you may find cheaper headphones that better match your needs.
