Summary: I use these ear buds at the gym while lifting and doing cardio. The noise canceling is decent but the inner portion is rather large, even with the smallest rubber gasket installed. If your ear canal is small, you will have a problem creating a decent seal for proper noise cancellation.The sound is good but not worth the premium cost. The ear buds do a very good job at amplifying the sound of any player.
Pros: Easy To Use, Improves Sound Quality, Improves System Function
