The AKG K553 Pro Closed-Back Studio Headphones use 2" (50mm) low impedance 32 ohm transducers in an advanced close-back, over-ear design to deliver a frequency response of 12 to 28,000 Hz. They are suitable for monitoring, mixing, and mastering applications.
The lightweight housing is designed for hours of comfortable use with extra large soft ear pads. The headphones have a 2D-axis fold flat mechanism for easy transport and storage.
With a 32 ohm impedance, the headphones can be driven by mobile devices and laptops. They cable terminates in an 1/8" (3.5mm) plug and comes with a 1/4" (6.3mm) screw-on adapter.
