I use these while exercising on an indoor cycle trainer. They're sweatproof, oomfortable to wear, and do a great job of blocking out external sound while I listen to the TV while I ride. Much quieter for everyone at home because I don't have to turn up the TV speaker volume in the room to hear. Don't know about longevity yet - just got them - but wires are heavier gauge than what I used previously.
