Recently, my Brainwavz M2's have passed into the void and I happen to have another, new unopened pair on hand. Should I open these or try to sell them for $45 (a little lower than what I purchased them for)? Just curious to what people may say about this decision. I already have a posting in the "selling/trade" section of Head-Fi for the $45 I mentioned, if anyone's interested. Anyway, any advice?
