Guys, I ordered a GT Sov. that should have been here today, (oh well, so much for 3 day air) and I am wondering if the old Depthmaster headphones I have from 1988 will work with it. I know they will work, but will that old Depth master technology make any difference or should I just use the "cheapo" headphones that Kelly Co. is giving away with it? I have a pair 2001 Depthmaster Superphones, but I dont have the compatible cord for the GT, I ordered one from the manufactuer, but it doesnt look like its going to get to me in time for my vacation I am going on this sunday. Just wondering what headphones to bring. Thanks, Aaron
