H2O Audio Tri Multi-Sport: One-minute review
The H2O Audio Tri Multi-Sport Waterproof Open Ear Headphones are a contender for our best waterproof headphones guide. Thanks to their dual Bluetooth/flash memory, these headphones are so versatile you’ll only need the one set for all your workouts, whether underwater or not.
Fully waterproof, they have surprisingly good sound in most Bluetooth conditions and from the onboard 8GB flash drive for uninterrupted play while swimming. Bluetooth’s limitations in water mean you need both modes if you never want to be without sound. While you could jerry-rig a smartwatch to your swim cap or goggles, keep in mind you’ll need the two devices within three to four inches of each other.
As with most bone conduction headphones, they’re worn on the cheekbones – an improvement over the H2O Audio Sonar (one of our waterproof headphone picks) which need to be attached to swim goggles.
Our main quibble is that the control buttons sometimes need a couple of attempts to perform how we want rather than working on the first try. Of the three function buttons, the main button controls a lot, so you need to be very precise with how you hit it and how long you hold it. This should improve after the button design change in the next production run.

Both on H2O Audio’s website and on Amazon, these versatile headphones are currently on sale at the time of writing. However, they retail at $149.99 (£128.00, AU$225.00). They’re manufactured in China and designed in San Diego, California. They ship internationally, though additional taxes and shipping fees vary by country.
It’s rare to find waterproof headphones, especially at this price, with both Bluetooth and onboard memory so you can have uninterrupted sound regardless of the conditions. For example, Shokz OpenSwim headphones have only an MP3 player (no Bluetooth) at a cost of $149.95. On sale for $89 (from $129) are the Bluetooth-only YouthWhisper SuperQ3 bone conduction headphones. While Zygo Solo headphones allow you to stream flawlessly from your phone underwater via an FM radio transmitter, it’ll cost you $299 and you need to bring extra gear to the pool.
H2O Audio Tri Multi-Sport: Design
- IPX8 waterproof rating means you can swim without worry
- Stream via Bluetooth or from the onboard flash drive
- 8MB of storage of MP3, WMA and M4A files
The H2O Audio Tri Multi-sport Waterproof Open Ear Headphones have the maximum waterproofing rating – IPX8. That means they can withstand immersion in 12 feet (3.6 m) of water for an unlimited time (so you’ve lost one more excuse for cutting your workout short).
Fairly typical for bone conduction headphones, these have two round transducers that sit below your temple, hooks that go over the top of each ear, and two rectangles that sit behind your ears with the controls and battery. The device is mostly black, though you have your choice of Caribbean blue, hot pink, or black for the band that wraps behind your neck. No need to worry if you expect to be tossed around in the waves, they come with a little rubber leash to secure them to swim goggles or a wetsuit zipper. For regular wear, you likely won’t need it – they stayed comfortably in place for us during a jog and while swimming laps.
Charging the headphones and downloading files to the 8GB flash drive is through a compact proprietary cable that pairs four metal circles on each device via a magnet. While you can’t sub one of your dozens of other cords in, you don’t have to worry if water will seep into the charging port.
Once the cable connects your headphones to your computer, a window instantly pops up to transfer files. Our headphones arrived with two dozen songs already loaded, and we can attest that Janis Joplin belting out “Me and Bobby McGee” energizes for several extra laps in the pool. It’s easy to drag and drop whatever MP3, WMA, or M4A (iTunes) files you like into folders and organize them by type, workout, or however you like. Note that you can’t download files from subscription services like Spotify or Apple Music because they’re copyright protected (but you can stream them via Bluetooth).
Three buttons manage the controls. With a click, two buttons raise or lower the volume; holding one skips to the next or previous track (or forward or back a few seconds on podcasts). In memory mode, a double click of a volume button skips to the next or previous folder. The main button turns power on and off, pauses and restarts play, and toggles between Bluetooth and memory. In memory mode, the main button also controls shuffle play and, in Bluetooth mode, answers calls as well as activates voice assistants.
The battery lasts eight to nine hours though playing at higher volumes will drain it more quickly. You’ll know your headphones are fully charged when their light turns from red to blue. A polite British lady announces the battery status when you turn the headphones on and she gives you an hour’s worth of periodic warnings when the battery level is low. She also confirms when you’ve toggled successfully between Bluetooth and memory modes.
H2O Audio Tri Multi-Sport: Performance
- Easy to download to the 8GB memory and organize files how you want
- Great sound, though a bit bass-y underwater
- Button controls can be a bit finicky
Because the H2O Audio Tri Multi-sport Waterproof Open Ear Headphones stream sound two ways, you only need this one set for all your sports needs. Overall, sound quality is quite good, especially for music and podcasts, though a bit echo-y for phone calls. In the air, both music and podcasts sounded great and were surprisingly rich, whether streaming by Bluetooth or from the flash drive. Underwater, podcasts’ sound quality was just as good as in the air. For music underwater, we would have liked more treble and less bass, but it wasn’t a deal breaker (and we were happy that the bass wasn’t so strong that our cheekbones vibrated, as with some other bone conduction headphones).
Because water blocks Bluetooth signals, sound did go in and out while swimming in Bluetooth mode when our head was even just a couple of inches below the surface. The headphones performed better at the end of the pool nearest where our phone was sitting and less well 60 feet away at the pool’s other end. Keep in mind that the headphones must be in Bluetooth mode to receive phone calls.
Swimming is why you want headphones with a built-in MP3 player. In memory mode, the sound was great and didn’t cut out at all whether we swam on the surface or dived to the bottom of our four-and-a-half-foot-deep lap pool.
Our biggest complaint is that the control buttons of the H2O Audio Tri Multi-sport are a bit finicky, especially the main button which controls play, pause, toggling between Bluetooth and memory modes, and a few other functions. Sometimes it took a few tries to get the device to do what we wanted; occasionally we gave up and just pulled out our phone to get the sound to restart rather than continue to try to hold the button for the exact right number of milliseconds. Now, most people won’t do the extent of toggling and control adjustments that we do during testing, but keep this in mind if you frequently want to skip ads, pause and restart play, or switch back and forth from Bluetooth to memory mode. In circumstances when your hands aren’t free (or dry) to use the controls on your phone, make sure you’ve downloaded enough podcasts or music to the flash drive so you don’t need to toggle and then don’t touch the controls once it’s playing how you like it.
We’re told that H2O Audio is updating the design for the next production run to make the control buttons bigger so that they’re easier to press. This is likely to reduce the problem significantly.
As with all bone conduction headphones, you’ll need to turn the sound up in noisy environments because, unless you also wear the supplied earplugs, nothing blocks your ears. The open-ear design is a safety advantage – you want to hear the cyclist or car zooming up behind you or if another swimmer is trying to pass. Unlike with other bone conduction headphones we’ve tried, there was very minimal sound bleed (and, phew, no complaints from the noise-sensitive person we share home and office space with).
The 8GB storage is a fairly standard size and generally means you can store 1500 to 2000 songs. Downloading files onto the headphones was drag-and-drop easy – our biggest challenge was finding MP3 podcasts and songs in a Bluetooth world.
