Hi guys!
 
As stated in the topic, I'm looking for information on these headphones. I own them, and I think they're great, but I would like to learn a little bit more about them. There's not much I've found on the subject on the Internet, so basically I just hope somebody here could provide me with some information. Really, any input would be great!
 
Thanks in advance!
