The Doritos' Guardians of the Galaxy 2 chips sold with a MP3 player containing the movie's full soundtrack, a pair of retro headphones of the sort that airlines used to hand out for free, even in coach, and a USB charging cable.
They're pretty cool — the buttons silkscreened on the back actually control the playback. The teardown reveals some clever, shrewd engineering to keep costs down.
They're sold out and going for stupid money on Ebay.
The limited edition Doritos bag includes: one (1) custom, built-in, fully rechargeable MP3 player loaded with songs from Marvel Studios' Guardians of the Galaxy Vol.2 soundtrack, one (1) separately packaged Doritos Nacho Cheese Flavored 3.125 oz. Tortilla chips, one (1) USB charging cable, one (1) pair of retro-style headphones
