For walking around school/jogging I use the AKG K 26 P.. They're okay, pretty cheap and small, easy to fold.. They've been lugged around in my bag a lot without using the carrying bag and haven't broke.. The sound quality is average, I don't have anything to compare it to, but for the price I can't complain. I was looking at these and the Sennheiser PX100's.. they both had great reviews so I just picked what look I liked more.
