Description of K553 MK2:

Closed-back performance meets open back sound

The 2” (50mm) low-impedance drivers provide strong, accurate, and distinguished bass response, with enough sensitivity for precise sound reproduction on laptops and mobile devices. Extra-large soft ear pads ensure stress-free listening over long sessions. AKG K553 MKII even features a detachable cable and 2D-axis mechanism that enables flat folding for easy storage or handling on the road.
