Query: Great earphones for working out

These earphones are great for what they are intended to be used for, working out. I would rate the sound quality as very good, not great, and not quite what I would expect for Sennheiser. That being said, I would still reccommend these to anyone looking for something that will stay put while working out, even while running.They do take a second to get in your ear at first, and I probably wouldn't recommend them to anyone with somewhat smaller ears.Bottom line, they are a great product, they will stay in place, they hold up well to abuse (bouncing around, sweat, etc.), and they sound very good.
