Pros: Great sound and isolation.
Cons: The earphones are kind of expensive.
Ultimate Ears is a very good headphone company. They have a wide variety of headphones, that range from the type you use with Ipod's and mp3 players to headphones for live performances. Big time bands that use these headphones are Anberlin, Rise Against, Switchfoot, and many more. I love the sound quality and the isolation from other sounds. The headphones range anywhere from 20 dollars to 1300 dollars, I love them. I have the 1300 dollar ones. This is a great buy.
