🏊 Swim in Harmony with H2O Audio Sonar - Underwater Waterproof Headphones with MP3 and Bluetooth Review

Please note this is a bone conduction device that attaches to swimming goggles. They work primarily by vibrating your skull. It's all good but the first time my girlfriend wore them she came out of the pool with a black eye. Yes, she wore her glasses tightly, but you have to somehow keep in contact with the skull. So the vibration went through the strap and must have vibrated the eyecup around her eye enough to actually hurt her. Yes she is a small and delicate person, if you have hard eye…

I was very happy with this model. I tried the headphones twice while swimming in open water. Set the volume to low and after 3 hits it started to increase and I didn't press the volume buttons until the sound was deafening. It gets so loud that I lose my bearings in the open water. Go to stop and turn down the volume. After 5 seconds, however, it increases again. Very annoying and instead of making my swimming routine easier this headset makes it a lot harder. What am I doing wrong? In…

I used them for the first time today. They worked great. It has breathed new life into my swim training. The only issue I had was that I was using it with my Apple Watch and the audio cut out when the watch was submerged in water. I'm assuming this is an issue on the side of the watch and/or the bluetooth signal not being able to get through the water. On a freestyle shot, the audio would carry when my hand was out of the water, but once it was in the water the audio would cut out. Luckily you…

I first bought the earbuds in H2O but couldn't get them waterproof. I liked the clip for the apple watch. I switched to SONAR and I really like it even though it doesn't have a clip for my watch. The workaround for the Apple Watch is to remove the strap and simply slide the watch under your swim cap from the back or side—the closer to your ear, the better. BlueTooth does not work underwater, so the smartwatch must be within a few inches of the headphones. You can use the shuffle button, that…

The sound is very good, but the fragility of the USB connection makes it unusable. When I first took them out of the box, I read the instructions, which basically tell you how unreliable they are and tell you not to touch them once they're connected. And they tell you that if the USB connection drops, you need to cycle your computer AND your headphones again to get them working again. Right out of the box they connected for a moment, but even when I put them VERY carefully on the charging table
