Query: Oh my God, these things are awesome !!!!

I have never been able to find headphones for my ipod that stay in my ear during exercise. I sweat a lot and do a variety of exercises to train for triathlons. Therefore, I am always plagued with my earphones falling out due to sweat, head movement, wind, etc. These headphones sound very, very good. I have never taken the time to write a review...but these headphones were worth the trouble. Don't waste any more valuable training time, buy the headphones !!!
