Summary: I really like they way they stay in my ears while running\working out and I love the volume\skip\mic features when they are hooked up to my iPhone. That being said, the sound quality sucks. Absolutely NO bass... They sound like you have a cheap pair of tweeters stuffed in your ears. This is my second pair of skull candy chops, I've used my other pair for 3 or 4 years they sound good and have held up to the years of abuse being stuff into my gym bag.
Summary: Purchased these headphones when my phillips in ear headphones died after the wire got caught on a hook at work. No matter which ear tips you use, these headphones do NOT stay in your ear. The hook or "chop" is a very bad design all together. The sound quality is the same as stock apple earphones (not the ear pods) The only thing I can worked well was the inline remote. Stay Away!!
