My swr amps have a headphone out jack. I've been thinking it might be nice to use that once and a while to maintain the balance between family relations and practice time... Anyone tried these Behringer cans? http://www.behringer.com/HPS5000/index.cfm?lang=ENG Seems like good specs for $35...not like I'm gonna be mixing with them...thoughts from users, or alternatives that are "effectively priced"...? Thanks!
