I own a pair of Crossfades and absolutely love them. They were given to me as a gift, but I like them so much that I would pay full retail to replace them if I needed to. Lucky you, these are way below retail price right now.
I own one of these for my Crossfade II Wireless headphones and love that I don’t have to switch to a dedicated gaming headset when I need a mic. It works with most headphones that have a removable 3.5mm cable. Currently $10 off, this is a steal.
