The flagship has arrived

If you're in search of reference-quality studio headphones, look no further. The AKG K812 headphones were designed to please the most demanding listeners: studio engineers and producers, who need to critically evaluate every nuance of a recording as they mix and master; and serious audiophiles, who want equipment that reveals new details in the most familiar recordings. That's what the K812 'phones were designed to do. And, wow, do they deliver!

No musical stone left unturned

AKG custom designed their largest headphone transducers ever — 53mm — for the K812. They are tailored for high headroom and wide dynamic range, so those dynamic peaks in your music come through with full power and immediacy. The Tesla magnet system is among the strongest available in a headphone and delivers precise stereo imaging with pure, powerful sound. The double-layer voice coil is ultra light for superior impulse control, meaning these headphones respond quickly and accurately to all the details of your music. It also ensures an incredibly wide frequency range, faithfully reproducing deep bass tones all the way to infrasonic frequencies.

AKG K812 reference studio headphones

Not just a showpiece

Durable, attractive, and comfortable, the K812's construction hits all the marks that audio engineers lust after. The over-the-ear design of the K812s offer a relaxed fit, while the open-back earcups ensure properly regulated airflow for a natural cooling effect as well as a wide-open soundstage. The large memory foam earpads and mesh headband are designed for long hours in the studio. Steel arches hold the earcups in place with hinges that allow flexibility for a custom fit. Altogether, it's a design that is luxurious, substantial, and inviting.

The K812's extra-long cable attaches to the left earcup's hinge with a 3-pin LEMO connector. The other end terminates in a 1/8" miniplug and includes a screw-on 1/4" adapter. The 36-ohm impedance rating makes these headphones great for a wide variety of listening devices, though they'll sound their best driven by a good headphone amplifier.

Praise for the AKG K812 from Sound & Vision

"The K812 is, without a doubt, the most open-sounding headphone I've ever listened to. Stereo imaging is breathtakingly expansive. Midrange purity is as good as it gets. "

— Steve Guttenberg in Sound & Vision, July/August, 2014
