I have an infant and apparently they need silence to sleep. I don't get it, but he sleeps when I consume my DVR, so I guess I need headphones. Could someone give me a crash course on what I should be looking for? I hear you can get surround sound a pair I've been looking at has what they call "Headphone 360" that says it provides 7.1 surround sound. That sound pretty good to me, also can you get any bass out of headphones? Or is that a dumb question?
