H2O Audio TRI 2 PRO Multi-Sport Waterproof Bone Conduction Open Ear Headphones, Bluetooth 5.3 for Running and Cycling, MP3 Mode for Swimming, IPX8, 8GB Memory, Playlist+ App Included for Streaming

Absolutely brilliant, I use for swimming and cycling listening to audiobooks. As I do breaststroke I can stream from my phone at the poolside. When cycling you can still hear traffic so it’s safe. Pottering around at home you don’t get sweaty in the heat like with my over ear headphones. Thoroughly recommend makes exercise a joy.

Not had it long, however compared to some cheaper ones I had the sound is amazing, (some vibration when your listening to metal at a loud volume). And it is true what they say on the forums, the sound is even better when you get in water! Compared to my previous Sony ones (functional but a waste of money imho) you can actually hear these properly when swimming.

Bought these because the concept is brilliant. In practice they’re a design that rewards only very specific ear anatomy — mine isn’t it. The pads sit on the cartilage, not the cheekbone, so at normal volumes they buzz against the skin and the sound is terrible. I tried every adjustment, headband and swim-cap trick, and they still won’t sit where they’re supposed to, not that I want to walk around with that look all the time. If you want bone-conduction that actually conducts through bone instead of vibrating your ear, look elsewhere. I’ve initiated a return and asked for a refund under my consumer rights — this product, as worn, is not fit for purpose. Consider this a friendly public service announcement: great idea, shame about the execution.

Brilliant piece of kit, I've upgraded twice so this is my third one, customer service is excellent and the ability to record anything playing on your phone and play back makes it perfect!

It was good until 6 months later the magnetic charging unit broke, tried everything as advised. Nothing worked , very disappointed, will now have to start all over again.

The headphones are good. I like the case. Regarding the confort, I would like them to be smaller, I mean the wire connecting both ends. I have a medium head size and it hags in my neck. We should have a couple of options regarding this. Sound is pretty good, specially when using the hear plugs. I just started having a little vibrations, like noise, saturation on the right end. I can't have it removed, seems to be inside the headphones. I hope they will go away the same way they appeared.

Much, much louder than the other well known brand, i like the weight because it helps the headphone stay on, they feel snug and secure on my head, also like the silicone band they supply as this makes the fit perfect. Wish they had supplied more than one. Now to the one annoying thing, they turn off incredibly quickly when using Bluetooth and you have paused the track, wish they allowed you to disconnect or at least a longer time before completely turning headphones off. The voice is annoying and I wish the setting went to Bluetooth first instead of playing from memory. All in all a good buy and I would repurchase

The quality of the bone conducting headphones was far higher than expected. They don't match hi end audio headphones but they are used in different applications. I picked these for the inbuilt MP3 player and the highest level of waterproofing. The Bluetooth connectivity with my phone is excellent and pairing is simple and quick. Getting the music onto the headphones was not, initially, straightforward as my IMac did not recognize the headphones as an external device. An online chat with the customer service department solved the issue, they send me a firmware update and all was well. I think a Windows PC will not require the extra steps. It was then a simple case of drag and dropping my songs into the storage folders in the headphones. In use they are perfect when walking, but the highest volume levels causes vibration, it's not a discomfort but noticeable. During my 1st run I thought they were bouncing on my head, they weren't but it took a while to get used to the feeling. During a race last week I didn't notice wearing them, I only heard the music. The main reason for buying them was that the race rules only allowed this type of headphones to be used as traffic noise can still be heard. Normal audio on-ear or over-ear headphones are forbidden. I also had the chance to swim in them, they are great. Maybe a little too much bass underwater but simply amazing. The customer service is fabulous, online and via email so very happy with the product and with the company that designed them. I score them 4.5 out of 5 only because the 3 operating buttons are small and quite close together. It takes a moment to locate, by feel, the one you want to press. I've not had the battery level drop below medium but I probably only gone 2 to 3 hours before charging. They are expensive but they are high quality. The manufacturer had a Mom's day (USA) sale and they were discounted when I bought them. No regrets about buying them at all.

Very disappointed. I bought this product over competitors because it was said to have higher volume and better bass. The treble and mid zone was ok. The bass was buzzing and distorted. The speakers did not contact my bone perfectly. The volume through bone transmission was not that good. Not worth the extra cost or delay ordering from abroad.

Entrené por primera vez y, a los 30 min de entrenamiento en piscina, la bocina derecha dejó de funcionar después de hacer un ruido raro. Muy probablemente sea un defecto de fábrica porque me parece increíble que se descomponga así de rápido. Aún así, mi experiencia no fue buena.

I've been using the H2O Audio headphones during my training, especially when I’m swimming and training underwater, and I have to say, they really hold up. As a triathlete, my swimming sessions are a big part of each workout, and having a reliable waterproof set of headphones makes a huge difference. What I love most is how well they perform underwater. The sound quality isn’t mind-blowing, but it’s more than enough to keep me motivated and focused during long laps. I can hear my playlist clearly, and the bass isn’t bad at all—definitely better than other waterproof headphones I’ve tried before. Plus, the audio remains consistent—no weird distortions or cutouts when I’m submerged, which is a big plus. They fit comfortably and stay in place no matter how vigorous my swim gets. I used to have issues with headphones slipping out or feeling uncomfortable after a while, but these stay snug during entire sessions. They're durable too; I’ve pushed through saltwater open water swims and chlorinated pools without any issues. Overall, if you’re serious about swimming and need headphones that can handle being fully submerged without sacrificing sound quality, H2O Audio is pretty much the way to go. They’ve definitely made my swim workouts more enjoyable and easier to get through mentally—music while underwater is a game-changer.

I tried the Shokz OpenRun Pro 2, and these sound WAY better and play much louder. They sound a lot fuller than the Shokz, with airy highs, natural mids, no tinnyness, and surprising richness in the lows for Bone Conduction. Amd there is actually some bass with these! Be aware that Bone Conduction is never going to sound as good as in ear, on ear, or over ear headphones. But for what they are they are quite good, hence the 5 stars. They also fit with a little more clamping force to ensure good Bone conduction, which wasnt the case with the Shokz on my head. Plus, you get onboard music storage in addition to Bluetooth, and they are fully waterproof for swimming. The drawbacks are, slightly less comfortable and less unobtrusive than the Shokz, and you can really feel the low end physically pulsing into the side of your head, and there is a good but of tickling sensation from the sound vibrations. I didnt have that with the Shokz, but that's obviously the tradeoff for having more volume and more bass. If you might be bothered by the tickling and pulsing sensation, and sound quality is less important to you, then you might prefer the Shokz.

It is faulty Keeps switching off after starting even when advised battery is high Brand new and it’s done this every use
