K612 PRO Open-Back Reference Headphones

The AKG K612 PRO is an open, over-ear reference headphone built for accurate monitoring in professional studios. Its open cup design gives a full, spacious sound with natural imaging, and a patented Varimotion diaphragm rounds out the tonal balance across a 12 Hz - 39,500 Hz frequency response. Computer-optimized neodymium magnets keep transducer distortion low, so quiet detail stays audible even at low listening levels.

Comfort is built into the design for long sessions at the console. A genuine self-adjusting leather headband finds its own fit for each listener, while aluminum arches and solid rivets keep the frame steady without adding weight. The fixed 3 m cable connects with a 3.5 mm stereo plug, and an included 6.3 mm screw-on adapter lets it plug straight into studio gear that uses a larger jack.

The K612 PRO fits mixing rooms and reference listening spaces where an open, airy sound matters more than isolation, and it works equally well for critical hi-fi listening at home. It is built for engineers who spend hours a day evaluating mixes and need a headphone that stays comfortable and accurate the whole time.
