Good price because it?s work very nice , 20 hours battery noise cancellation good quality, i know what Im saying because Ive been a truck driver for six years and in the truck stop these headphones have cost about $100, but why overpay if the quality is the same ! Id like to return them, but I bought them knowing I was taking a risk. - I used the straps that came with the carrier to tie it to the roof rack rail on my SUV. However connecting to my laptop was a nightmare! I contacted Sennheiser customer support and got the same part number as on the packaging these were received in. I liked it so much I bought a second unit. Keys lost, she says. Thats all I can say. Overall Im very happy with it. The volume buttons are backwards, I have to press the one located on the bottom to raise the volume, and vice versa.
