I got these for use while doing long runs. These have worked the best for me in terms of staying in place and being comfortable. I have worn them as long as 3.5 hours running. After a while, the right bud comes unseated and needs to be reinserted periodically. I suppose my right ear is not a perfect fit for it. I have other buds that seem to produce more punch and range for sound quality, but these still sound decent. By comparison... The two kinds of Sony ear hangers I have slip out of my ears when running and continually need to be pushed back in. The Sennheiser PMX70 buds do an excellent job of staying in place, but become painful after about 30 minutes -- the buds ram too far into my ear canals. I also have Koss Noise Isolating Earbuds which sound great, but will not stay in place for more than about 15 minutes. Then sweat makes them slippery and they will not stay in much any more. I suggest taking the cord clip for another set of earbuds and using them with the Skullcandys as it takes tension off the cord and helps them stay in place.
