Themba Mbongeni Nkosi (born 6 December 1983), also known as Euphonik, is a South African DJ and music producer.

His early love of music was fuelled by artists his father listened to – the likes of The Spinners, Marvin Gaye, Stimela, and Hugh Masekela.

His Saturday show, Ultimix Weekend Edition, featured new music and mixes from DJs across South Africa and international borders.

The show involves 30-minute mixes and is used as a platform to showcase DJ talent of some of the world's leading dance artists and musos.

[5] Euphonik has travelled the world and has played in places such as New York, Miami, Ibiza, Dubai, UK, Spain, and around Africa.

He has shared stages with Tiesto, Swedish House Mafia, Avicii, Afrojack, Hardwell, Skrillex, Nicky Romero, Deadmau5, Louie Vega, and Richie Hawtin.

[6] In 2013, Euphonik's song with South African DJ Fresh and Nyanda, "Cool and Deadly", rose to number one on the 5FM Top 40.

[9] Since adopting his first name as his stage name, he has worked with a range of South African singers, songwriters and percussionists to produce original techno and house tracks.

[citation needed] He and Superga (an Italian shoe company) collaborated in 2012 and brought out a limited edition black and gold Euphonik sneaker.
