Ive heard of some groups that will exchange headphones with each other. I guess through the mail. Would love to get into that action.
Better yet, remember those mail order music retailers in the '90s that said something like “buy 10 CDs now for a nickel and buy 3 more at full price within the next year!”? As long as you bought those 3 more it was a great deal (if you didn’t you paid full price for all those 10). Something like that for audio gear would be fun. Will never happen. But would be fun.
