I use these to workout, plugged into my iPod, and have been doing so for years. They stay snug, don't shake around, never fall out, whether I'm hanging nearly upside down doing a decline bench-press, or doing some running. Look at the price! They sound great, and they last longer than other, more expensive headphones I've bought. I use them all the time, 5 times per week, over an hour everyday. They don't last forever, but for the price paid for them, this is probably a best buy. I am kind of afraid that Sony will stop making them because they are "too simple" or "too practical." I also like how unassuming they look. You see these guys working out with either the mega-huge studio headphones (huh?), or those very strange, extraterrestrial wrap-around-my-ear-weirdness things. Folks, this is where it's at. Buy a pair. Heck, buy two!
