So I have some Sennheiser 555's which are cool, but I can hear everyone chattering around me on the cube farm. Are there any Wireless AND Noise Cancelling headphones out there? I have not been finding them. <$100 would be cool but I would go up to $200 if I had to.

1. The SG stands for “solid guitar.”
