Input:
I bought these to use when playing electric guitar, so I don't disturb  my wife and neighbors with my bad playing..  I wanted something comfortable, durable, with a long cord.  These fit the bill perfectly.  They are well built, fold easily, and fit in a durable bag easily.  The sound quality is excellent.  I've heard static a couple of times when shifting the guitar, but that's not the fault of the headphones.  I have a medium sized head, and they fit me snugly but comfortably.  I can get a bit of nausea when using them, but not nearly as bad as some other headphones I've tried.

I'm very satisfied with these headphones, they are well worth the price.
