Brand new pair of Sennheiser PXC 450 Noise Cancellation Headphones. They have only been tried on once but never used, they have just sat in the case since I bought them. These are one of the best noise cancelling headphones on the market, they have been reviewed on par with the Bose Quietcomfort 25 headphones for a much lower price. Once nice feature that these have which most don't is a pass-through which allows you to disable the noise cancelling and amplify the outside sound so you can hear without having to remove the headphones. They come with the case, new battery, 1/4" adapter, dual 3.5mm adapter for airplanes. They were $200 new, asking just $60.
