I am currently using a Bose IE2 to listen to music and while at the gym. The ear pieces are so comfortable around your ears, you can barely feel that they are there. The sound quality is excellent. However, if you're a heavy bass listener, then I wouldn't recommend this product because it lacks on bass production. I wish that the cables were a little thicker (or durable), instead they look like they're a bit cheaply made. Overall, I am very satisfied with this product and will definitely buy another headphone product from Bose!
