H2O Audio TRI 2 Multisport Waterproof Bone Conduction Open Ear Headphones, Bluetooth 5.3 for Running and Cycling, MP3 Mode for Swimming, 8GB Memory, 8.5-Hour Battery, Black

For context, I tried almost every brand of bone conduction headphones on this site. Keep in mind that bone conduction headphones will never have the quality that a good over-the-ear headphone or even in-ear earbud can provide.Summary: Best audio quality, for a high priceSound quality: excellent for bone conduction, rich and warm and full. Can feel buzzy at loud volume.Comfort: not quite as comfortable as shokz, but not badBattery: good - never tested to exhaustion.Call quality: goodOverall quality: very goodControls: always started in mp3 mode, couldn't figure out how to change that and it was kind of annoyingBluetooth: easy to pair to multiple devices, performs wellOther: came with the best case

I am extremely satisfied they work great battery last a long time in the sound is phenomenal. Would recommend anybody.

These work very well for running and swimming but there are three quirks that are annoying. First, when turning on, it starts in internal memory, which is probably fine when you get music stored, until then it's annoying. Second, the on/off/select button (the middle) is hard to distinguish if you have big hands and it can be difficult to tap it just right. Sometimes it goes into bluetooth mode, and sometimes it goes into pause, from pause it basically does nothing and you have to restart. The third, and possibly the most annoying, is that is shuts down if it does not receive a signal. When actively listening, this is not an issue, but these are not recommended if you pause the music or are using on a conference call, as they will shut down while you're speaking after 5 min.

Purchased them back in January 2025. Used them for swimming and running. The Bluetooth connection works good and did not skip songs. Playing from memory sounds would repeat and go out of order. My main issue, battery. Forgot to turn them off once. After I recharged them they will not turn back on.

Was looking for a bone conduction headphone for my husband and came across this as a recommendation for productivity and for use as possible work out headphone/head piece. He loved them and really likes (and sometimes thrown off) that he can "hear" music but also hear his surroundings without needing to take anything off or out of his ears! One downside to these is if you wear glasses, it does get in the way. But if you can make do without having to wear glasses while using these, then don't if you are able to or if you can bear with the double arm feeling behind/around your ears. Overall, we both love the technology and development of these and we're both hoping to see what other music/media listening devices come out in the future!

I am a waterman who does anything from channel crossing paddling, open water swimming as well as downwind foiling. I could not do any of these activities without music. These headphones work in any conditions in the middle of the open ocean. Also they will endure high amount of usage. I put hundreds of hours on my headsets and never had an issue. Highly recommend this product.

One of the earpieces vibrates all the time, which results in a tickling sensation. Also, when it is windy I struggle to hear from these headphones given the open ear design. Not what I had expected.

Currently using them to swim using a snorkel. These are 2X louder than other cheaper knockoffs. If you can wear them so the receptor is slightly above water, THEY DON'T CUT OFF BLUE TOOTH! even slight contact with my earlobes at 75% volume is good enough to listen to audiobooks. Gym noise and music will not overcome this set.
