2 sets of OEM wireless headphones fits most 2001-2015 Chevy, GMC, Cadillac, Buick with Deluxe sound system and DVD player. I only took one set out of the packaging for the pictures. Both sets are identical. I will ship to the winning bidder USPS Ground Advantage ASAP upon auction close and completed checkout. Usually the same or next business day. We don't drag our feet when it's time to ship.
