Bests & Worsts Reviews from Amazon

The sound is very good but the USB connection flakeyness makes them unusable. When I first took them out of the box I read the directions that essentially tell you how flakey they are by telling you not to touch them once connected. And they follow up by telling you that if the connection to the USB is lost then you have to cycle the power on your computer AND the headphones to get them to work again. Right out of the box they connected for a moment but even as I VERY gently set them on the desk to charge for the first time the connection was lost. I rebooted the computer and the headphones...still no connection for data. Charging works just fine though. Their last hint was to try a different USB port...so I did that mor gently that I have EVER done with any usb device as not to disturb the the connector on the headphones...and it worked! I moved my keyboard far from the overly sensitive headphones and began to transfer some podcast mp3 files along with about 20 songs. The instructions say that you can organize your files into folders like “podcasts” and “music” so I did that. All the files transferred but strangely very slow. After they finished charging I took them to the pool excited to give them a go! Well...this is where the disappointments really started. The instructions to tell the player to go into the first folder (click the “M” button twice) did absolutely NOTHING! No mater what I did - nothing in the music or mp3 folders could be accessed. The only thing that worked is the stock files in the root folder. I thought, well that is “blanked” but decided to dry off and put the music in the root instead and give it another try. I plugged the dry headphones back to their little SUPERSENSITIVE little magnetic connector so as to ensure nothing was going to disturb them AND...nothing. Would not connect at all. Ok...I rebooted (cycled the power all the way off and waited 30sec before turning back on) the computer and the headphones. This time I first connected the magnetic connector to the headphones to ensure they would not move at all when I plugged the usb end into the computer. I ever so gently plugged them in again and....NOTHING, again. So I very gently unplugged the USB end and tried all the 5 other USB ports - each did...say it with me now...NOTHING! So most people would pack them up and ship them back, but me, nope...I’m way to stubborn than that. I tried the power cycling thing at least 8 more times. Note that the power charging function of the USB connection never failed once, just the data. I even cleaned all the contacts with electronic contact cleaner and a q-tip. Can you guess what happened...NOTHING!!! So I thought, maybe turning them off over night might do something, anything, to make them connect. This morning (the next day) I gave the computer and the headphones one more shot from a fresh, rested evening of both being shut down. Yep, h2o Sonar headphones are brilliantly consistent in their design and quality...NOTHING happened again. So I thought maybe my USB ports are confused (as hinted at in the directions because it couldn’t possibly be the design) and needed a reset. So I looked up how to reset the usb controller on my Mac...I’ll give you a moment to contemplate what happened next...nu...nu...”NUTHING”, LOL! Why is it that these can connect via Bluetooth but they don’t have a way of loading using that data stream...seems like a much better idea for waterproof items (and clearly more reliable than the current method). C’mon engineers - you really need to figure this out. Lastly - the bluetooth streaming works just fine but it’s next to useless when swimming because Bluetooth can’t penetrate water. Ive got much cheaper and better sounding options for non-swimming headphones. I’ve ordered a replacement to see if this was an isolated experience. I’ll update the review if anything new comes of it.
