I use these for exercising. They are near perfect, the ear piece might be a little uncomfortable for the ultra-sensitive, but I find the headset to be comfortable and durable. Very good audio quality, which surprised me because the Fry's Electronic salespeople steered me toward the Motorola, Rocketfish, etc models (I tried them all), but this is the best of the bunch in my opinion of the under-$100 headsets.
