THE XUnknown X

MONSTA X – THE X (Unknown X) 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 photocards. 2 photocards are announced. One photocard is drawn at random out of 6 designs: two copies do not give the same cards.

No POB is listed for this version in pocabase. 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, DIGIPACK / Limited, UNKNOWN X / UNDERDOG X / HELLO X / XX / Random, and MD Limited. The tracklist does not change from one version to the next: only the box, the photocards and the artwork do. The declared contents of Unknown X match the other versions: the database records no difference in items.

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. No EAN is recorded here. The EAN is the 13-digit barcode that names one precise version: it is the safest check before buying.
