Negative Positive
Title: uncomfortably does its job
Review: 4 star because the pain of inserting this thing correctly killed a star. It is a b*tch to get on right, but sounds great afterwards and does not come off during workouts. The music may sound like it lacks bass, but that was before I got the hang of putting it on. If it is too deep in your ear, you will notice muddyness in the sound. Decent bass and crisp highs, I'm satisfied.
