Best headphones I've ever owned. I have over-the-ear for home and in-ear for traveling, gym etc. The over-the-ear are extraordinary - I hear songs that I've listened to all my life differently.
Only thing is, their system, a vented diaphragm design that incorporates a large air chamber that allows the sound to go out, means the person next to you can hear the music. Which is why I own a pair of in-ear as well. Because I want to rock out to Barry Manilow while on the 5 train to the Bronx, without loosing my street cred.
