Query: don't waste your money

If I could give these negative stars, I would. I bought these thinking they'd be great for the gym. WRONG. They continuously fell off, so often it was annoying not only me, but the girl on the treadmill next to me. Not only that, but the ten seconds they did stay on, they bounced around and made a rattling noise so loud, I couldn't even hear the music I was listening to. I highly recommend you forget these duds. I'm going to purchase another pair of Sony h.ear MDR-J20 headphones, which is what I bought these to replace because I slammed the car door on the cord of my original pair.
