About this version
MONSTA X – THE X (UNKNOWN X / UNDERDOG X / HELLO X / XX / Random) is one physical edition of the 13th mini album by MONSTA X, released on September 2, 2025. This is a physical CD: disc, photobook and cards in one box.
The album holds 6 tracks.
The box declared by the distributor holds 2 photobooks, 4 photocards, 2 posters, 8 sticker sheets, and 2 lyric booklets. The photobook runs to 100 pages. 4 photocards are announced. One photocard is drawn at random out of 6 designs: two copies do not give the same cards. It also holds UNKNOWN X ver / UNDERDOG X ver, Bookmark, and Photo, as declared by the distributor.
3 POB are listed for this version: KpopB2B gives Pre-order Benefit and KPOPHERO Wholesale gives Folded Poster : Pre-Order Only (1ea). The preorder window at KpopB2B closes on July 30, 2025. A POB (preorder benefit) is a bonus from the retailer, never from the label: it changes from one shop to the next and is gone once the preorder window closes.
THE X comes in 10 versions, among them UNKNOWN X / UNDERDOG X / HELLO X / XX / Random, DIGIPACK / Limited, MD Limited, and MD. The tracklist does not change from one version to the next: only the box, the photocards and the artwork do. UNKNOWN X / UNDERDOG X / HELLO X / XX / Random declares more items on these points: 2 photobooks, 2 posters, and 8 sticker sheets.
This is an official edition: bought from an authorised retailer, it counts towards the Hanteo and Circle charts, which measure physical sales in South Korea. EAN 8804775456800 points to this exact edition: it is the code to check before buying, because every version carries its own.
