The men and the legacy

The roots of MYSPHERE 3 go back to the legendary flagship headphone K 1000 of AKG, introduced to the market in 1989. Two outstanding acoustic engineers are associated with the history of the K 1000: Helmut Ryback, who developed the AKG K 240 DF, at that time reference headphone for many radio stations, and Heinz Renner, leading in concept and development of the K 1000, together with Helmut Ryback.
