Incredible Sound in the water, riding my bike, or hiking in the mountains!
I bought these after comparing them to other similar products. The sound quality, especially under water makes my swims so much more enjoyable. When riding, I don’t lose any situational awareness and can hear both the music and cars coming up from behind me. I am proud to support a small business and see them grow! They came quickly, the packaging was really fun to open, and they paired easily to my phone. Battery life is longer than I anticipated and easily outlast my hardest workout.They are lightweight and comfortable to wear in all environments. Since they are waterproof, I don’t have to worry about using them in the pool, the rain, or when I get sweaty. Nice job H2O Audio!

These things are awesome
I’ve been using the H2O Audio headphones during my training, especially when Iâm 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 isnât mind-blowing, but itâs more than enough to keep me motivated and focused during long laps. I can hear my playlist clearly, and the bass isnât bad at allâdefinitely better than other waterproof headphones Iâve tried before. Plus, the audio remains consistentâno weird distortions or cutouts when Iâm 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; Iâve pushed through saltwater open water swims and chlorinated pools without any issues.Overall, if youâre 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. Theyâve definitely made my swim workouts more enjoyable and easier to get through mentallyâmusic while underwater is a game-changer.

They don’t work with Bluetooth
Bluetooth doesn’t work (the device turns off immediately after connecting). Also, the device leaks sound. The sound quality from the onboard audio files is nice, though.

Love the ability to record audiostreams using phone and playback while swimming
after reading lots of reviews and comparing models i got this. The ability to record audio streams and then playback while swimming is a great feature. The sound quality is good and the battery life is adequate. Lasts a few hours or more. IT is quite comfortable to put on and i was able to loop it through the headstrap of the swimming goggles and also tether it using the provided keyhole style plastic strap. Have not used it much for phone calls but for what i needed it to do it is awesome. The Shokz and other brands are all mp3 players and work great for bluetooth. But in today’s day with spotify and other streaming music services, who is going to use or even owns their music at this point?

Very good headphones
I edited my review from 1 star to 4 stars. I had received my headphones with a faulty USB charger(1 pin broken) and the worst battery life. After buying another USB charger from H2O Audio website and resetting the headphones my experience improved.The audio quality and the Bass is excellent at low and medium volumes. Playing at maximum volume is quite uncomfortable. I use these headphones in long distance running and they are very ok.After H2O Audio advising me to reset the headphones, battery life improved from 2 to 4 hours in Bluetooth mode. This is enough for my distance running, but the advertised battery life of 6-9 hours seems to be theoretical and impossible for me to achieve. Am actually getting half of the advertised battery life.My suggestion to H2O Audio: kindly include 2 USB chargers in the package.

Super nice open ear bone induction workout earphone.
Amazing technology. Fit perfectly and great to run and do any workout including swimming. I appreciate the open ear design. Sound has perfect amount of bass. Worth the money!

Highly Recommend!
These headphones are perfect for swim training! Most bone conduction / waterproof headphones have poor sound quality but these have great audio quality even while in the water! The fit is great and they are super comfortable even during longer swim sessions. Iâve done 3 hour long swims so far and they have plenty of battery left. Highly recommend this product!

Trading silence for physical distraction.
I had done hours of research looking at different headsets that could help increase situational awareness while exercising.I settled upon these because it’s durability was highly rated.But I also really thrive when I am able to hear the bass in music. Granted bone conduction does not have the physical capability to do the same , I knew what I was getting myself into when I bought these.What made me hit the return button was how poorly these fit on my head. I have a smaller head, and wear eyeglasses and usually exercise with a cap. For maximal sound, these had to sit on a very specific part of my face. Wearing eyeglasses made it a little tricky. But with the cap and general movement, they kept shifting. I was able to hear my surroundings but had to keep fiddling with the headpiece.And if I wanted more bass, I had to put earplugs in.If the company incorporates their durability with features of a competitor (two size offerings & air conduction bass), this headset would be gold.

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 increÃble que se descomponga asà de rápido. Aún asÃ, mi experiencia no fue buena.

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 itâs safe. Pottering around at home you donât get sweaty in the heat like with my over ear headphones. Thoroughly recommend makes exercise a joy.

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!
