I've had these for a while now and just wanted to share. These have worked amazingly awesome for me in the gym and everywhere else. Completely sweatproof. Durable, comfortable, and out of the way. Kinda pricey, but one of my favorite purchases to date. Not the best design ever as there is some work to get the wire to the perfect length. I would've preferred no wire at all or one that is shorter or detachable. Ear cushions are adjustable as well as wire length. Most of all, they sound great with good, deep bass, and loudness, and are totally hands free in the smallest form possible. Plus, they work for 8 hrs. on a single charge so I have enough battery to last me throughout the day. I also like that, as a guy, I don't have to look like i'm wearing Princess Leia-like ear cans and that they don't rub against my neck or keep me from resting my head on a bench, like some do with a rigid head piece around the back.
