These things are great! I dont use them for my phone but I use them for mac. They block out background noise and they also dont produce too much noise outside the headphones. The only 2 things I would complain about is the bass and pitch. I like bass in my songs but the headphones add a little bit of a boost that will eventually give you a headache. Since I am using Itunes I can easily reduce it though. When you fast forward and rewind from the head phones the pitch changes a couple of times but eventually straightens back out. They have pretty good range where I can sit 20 feet away from computer and still listen to my music comfortably. Best set of headphones I have ever bought!
