K553 MkII
OVER-EAR, CLOSED-BACK, FOLDABLE STUDIO HEADPHONES
www.akg.com/pro
The K553 MkII is a closed-back, over-ear studio headphone for monitoring, mixing, and mastering applications. The K553 MkII was designed to
provide the perfect balance between the noise-isolating qualities of a closed-back headphone and the spacious, dimensional sound of an open-
back design. The 50 mm drivers provide a strong, yet accurate and distinguished bass response, as needed when monitoring and mastering
contemporary music. The extra-large, soft ear pads ensure comfortable, stress-free listening for hours, and the 2D-axis mechanism enables flat
folding for easy storage or handling when on the road. With its low-impedance drivers, the K553 MkII is sensitive enough to be used on laptops
and mobile devices, making them ideal for travel or critical listening on any device. The soft high-quality detachable cable is equipped with a 3.5
mm (1/8") plug, with a screw-on adapter to 6.3 mm (1/4") also included.

KEY MESSAGES 6
LEGENDARY AKG SONIC PERFORMANCE
Building on a 70-year legacy of continual design innovation, AKG delivers
unmatched sound quality and comfort. The K553 MkII represents the
culmination of decades of refinement—from the transducers to the fit and
finish.
CLOSED-BACK DESIGN, OPEN-BACK SOUND QUALITY
The K553 MkII was designed to provide the best of both worlds: a closed-
back design to provide noise isolation with an open and detailed soundstage
normally attributed only to open-back headphone designs.
STUDIO SOUND ON THE GO
With a foldable design, the K553 MkII can be easily transported. The design
minimizes the exposure to damage that comes with the demanding mobile
lifestyles of musicians, producers, and audio engineers.
FULL, DETAILED SOUND
When you’re serious about your music, you’re looking for more than
thumping bass in your headphones, you need nuanced low frequencies.
The K553 MkII offers 50 mm transducers to create greater low-frequency
extension and detailed bass reproduction, making it easier to hear the
program material as intended.
BUILT TO LAST
After decades of the strictest product standards and most rigorous of testing
regimens, quality has become synonymous with the AKG name—and these
headphones are no exception. From intensive driver stress tests, to an
80,000 bend cycle for cables—even an exaggerated drop test—we put
our headphone designs through the gauntlet so you can count on them for
years to come. Additionally, the cable and ear pads are replaceable, further
extending the life of your investment.
