I've just upgraded my plasma m-frame so I decided to sale these. Frames are in good shape other then the mark on the top of them and the springs don't bounce back into place as they once did. All in all they held up very well . Ear socks will need to be replaced. Fire iridium heater lenses are cracked At the nose bridge and at each end. Altough they are cracked the seem to stay in place well. They will need to be replaced but if they are handled gently they should last a little while. Looking to get $215 shipped Or best offer or trade for a different color mag m frame.
