My Sony headphones had one issue, which cost $60 to repair, they came up with 4 additional and unnecessary repairs to have a functional headset (+$185), which makes it cheaper to buy a new one. And you are required to do them all, or none. UPDATED: They proposed afterward to take off one of the repairs, but "took off" the overall promotion, going from 60 to $120 to change the power board when you only need to screw it. They are sending it back for free though, it was a waste of time but it didn't cost anything. I'll do it myself!
