Query: Great for running

Great headphones for running. Even a fairly hard tug at the wire won't pull them from your ears. They also work well for mountain biking, although the over the ear design is a little tricky when wearing a helmet and sunglasses - still the best option I've ever found though. Well worth the money.June 5, 2012 Update - these headphones are still going strong. I love them!
