Who the hell thinks its ok to ship a pair of 500 dollar headphones in a cardbox board box with ABSOLUTELY NO PACKAGING MATERIAL.
My question is, what kind of damage can be sustained through the shipping process, and is it even worth me sending this set in for a service. I doubt they will change out the drivers for a set of new ones if they were damaged at all.
I wouldn't worry about the packing materials, or lack of. Looking at the condition of those headphones, it would be like worrying about wearing protection when you are about to make love to a pregnant woman.
If the phones seem to be working OK, I'd invest in a pair of new grills and new pads. If you have one of the original HD650's, I'd definitely say this would be the way to go. And later down the line, you can upgrade the cable.
