Just posting my thoughts, got these during the BF deals, they do hurt your ears if you keep them on for more than a couple hours, but I think these are fantastic for the price. Sound quality for bluetooth headphones is really good, bass is just fine. The battery life is amazing.
I really hate the bright blue light on the side, but I taped over it and its alot better, I may take them apart in the future and pull out the LED. Other than that and the extended wear pain these are great.
As long as your fine with the caveats these are a terrific value for the price and I'd recommend them to a friend.
