1st of all, I have huge head, so I had to cut the back band off because they wouldn't go around, that might be the big problem right off the bat. however, the in ear silicon pieces were a lot harder to install than they were supposed to be. I cut too much off and they wouldn't stay in. the sound sucks, which I expected all things considered. the cable is very thin considering this is supposed to be a high grade component and was expensive, yet corners were cut on it. they're great if you're in the pool chatting or cooling off and listening to music. however, if you're swimming in a pool trying to work out and listen to music in the process, they pretty much suck.
Pros: they play underwater
Cons: hard to get to stay in ears, inconsitency in getting them to play consistent osunds
