Bowers & Wilkins PX Wireless Noise Cancelling Headphones​

I'm cleaning out my headphones to help pay for my Susvara and I found several great headphones that I just don't use like I should. These are the PX headphones from B&W and are in good condition (they hold up fine, but you can tell they aren't brand new.) They come in their keep pouch with an audio cable for direct connection and a charging cable. They sound wonderful! Here are the specs:
