MySphere 3.2 with “Standard” and extra “Treble” Sound Frames - Balanced and Single-ended Cables
Lightly used in a smoke-free environment. Premium foam-padded travel case, user manual, cables and extra “sound frame” included.
"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.
After extensive evaluation of all available transducer principles, including electrostatic and orthodynamic drivers, the developers decided to adopt the dynamic driver method for the K 1000, mainly because it is far superior for accelerating the air molecules at low frequencies. A novel radial magnet array was designed to minimize the influence of mechanical parts in the sound field. In order to avoid nonlinearities of the membrane movement the idea of the quadrangular shape was born."
