Yesterday I stepped over my wireless headset while is was hanging from the microusb cable and broke it. Thankfully it is very well designed so the earpiece part goes with some kind of epoxy compound inside so the damage was very light even when I crushed it with working shoes (those with metal in the tip). The fix was just to place a washer in the screw and resolder the cables.
There is a dock for the special edition MW3 of the headset: gamingmodz.com/images/products/accessories/xbox/mw3-wireless-headset.jpg but it is a bundle and I don’t need another headset for now.
