Input:
I love these headphones.  I used to have a pair of electrostatic headphones that were destroyed, and I've been wanting to replace them for so long.  These fit over the ear and are incredibly comfortable to wear for any length of time.  Even using them to listen to an audiobook is a pleasure.  Music comes out perfect.  The amp feels cheap, but it does its job well.
