I really wanted to like this product but it just wasn't worth the "half the work". First, the app never worked. So if you buy it for music downloads and not bluetooth, DO NOT BUY IT, IT WON'T WORK. The app is in Chinese and when you type nothing comes up - I tried so hard and even downloaded the Chinese keyboard for about 4 hours - even got my email address (I read forums that said it works could) entered into the phone number box. but in vain. I tried to contact the app creator and the brand's customer service but got no response. Then I found that my Bluetooth might work, so I uninstalled the app and took my headphones into the pool to try it out. Sound quality is harsh at best, constantly clipping from one or both ears, and when you're circling, it doesn't work underwater or when you're breathing in one direction. Headphones sometimes turn off completely. In general, if you want to hear about 20% of the song while swimming, buy it, and if not, find better headphones.
