For sound quality and running long distances these are great!

I run around 400 miles a year and cycle over 3000 miles. We bought two sets of these at a product show before a big event in our area. They have a decent sound and seem to do okay on short runs but longer runs with sweat they just do not hold on. The man who sold us these at the show said they were good for cycling: that would be a "no", no these are not good for cycling the wind noise they generate makes them not good for cycling. They were 40ish dollars a pair and I would have been okay if I would have been informed that they are NOT good for cycling. It's time to retire them.
