Binary Code is the fifth extended play by South Korean boy group Oneus.

The EP contains the lead single "Black Mirror", a rock version of their debut song "Valkyrie", and three new tracks.

[1] Puah Ziwei, writing for NME, noted that the lead single "Black Mirror"'s music video "seem to draw inspiration from the late Michael Jackson" and the "lyrics also reference a number of the late pop icon's hits, including 'Bad' and 'Man In The Mirror'.

Dazed stated " There's the slap of funk bass and washes of strings, elements that comprised the backbone of 1979's Off The Wall, but ONEUS's composers have recalibrated the analogue into a cool, impersonal sheen of digital production.

It's a canny twist; a thumping, computerised nu-disco backdrop for the song's flesh and blood lament – the loss of human connection within the technological age.
