I purchased these headphones as a gift for my dad who does a lot of working out in his basement. He absolutely loved these headphones. He could wear them while running on the treadmill and not have to worry about holding onto his Ipod or where to put a cord. These headphones were very comfortable and worked really well. It was easy to set up and allowed you to move around and not have to worry about dropping your MP3 player. The downside of these headphones is they stopped working after a few months. We believe it was because they got a little wet from sweat. I bought him another set hoping that maybe there was just something wrong with the original ones and the same thing happened again. After a few months they just no longer worked. These headphones may be better off being used for less active activities. They may work perfectly for cleaning or something that would not allow sweat to get into them.
