I was in need of a pair of cheap headphones for my elite. One with volume controls. I found these Garrett Master sound headphones on the bay for $13.49 shipped. The box is a little tattered, but the headphones are BRAND NEW! still in plastic. These are the same headphones (but with 1/4" plug) as the AT Pro. IMO a great deal for the frugal.
