EKS is a Finnish DJ hardware manufacturer based in Espoo, Finland, originally established in 1955 under the name Voimaradio Oy. The company pivoted to digital DJ technology and became one of the first manufacturers to bring a digital DJ system to market with the XP10 USB DJ controller in 2001. The XP10 featured an integrated audio interface and set the stage for EKS's reputation as an innovator in the DJ controller space.

EKS is best known for the Otus product line. The original Otus, released in 2008, is a dual-deck USB controller with a high-resolution 7.5-inch illuminated jog wheel and integrated multichannel audio output. Designed to fit on top of or in place of a standard DJ turntable, the Otus earned praise from European DJ publications and was dubbed "The Bruce Lee of DJ controllers" by MusicRadar. The Otus RAW, a follow-up model, added physical pitch faders for each deck and expanded configurability, positioning it as one of the most customizable DJ controllers available. EKS also produced the more compact and affordable XP5, a portable single-deck USB controller with an integrated sound card, aimed at mobile DJs. The company's XMAP MIDI Mapper software allowed users to create custom controller mappings for various DJ applications.

EKS has 1 product cataloged on Equipboard, including DJ Controllers. Their gear is featured by 2 artists, with the strongest followings in Electronic. Notable users include Seven Lions and Darude.
