Excerpt: I am an older woman (72) and I wound up exchanging the earphones for ones that went across the top of my head. I just couldn't get the behind the head earphones to stay on. Maybe it was me. I am very happy with the replacements by ear pollution.
Summary: I have the older version of these, and there about 6 years old now, and I only have two problems with them, one is the cord is a little too short, and the other is a small occasional rattle/clicking in the right speaker
Summary: Someone who uses headphones designed this one with everything that you need. Very rarely do I find a product that I like everything about it, but this is one. Sound quality, volume control in a handy place, compact design, behind the head design with the fold-up feature. I bought a second set before they stopped making them.
