The starting bid for this one is $399.99 or you may use the "buy it now" feature on eBay to get it for $499.99. Check the Capitol 1524 auction here (Read the EDIT below). Looking at its price I suppose the Shure Headphones are not included with this item.

EDIT: after contacting the seller I confirmed the Shure Headphones are not included, but the Bose-in-ear headphones are now included (picture at the right). The item has been relisted here .
