AKG K812 Superior Reference Headphones
The AKG K812 delivers an open, spacious listening experience with exceptional comfort during extended sessions. Purpose-built for critical monitoring and mastering work, these circumaural headphones combine precision engineering with thoughtful ergonomic design, making them equally suited to dedicated control rooms and tracking sessions. The open-back design and carefully tuned 53mm transducers reveal detail across the entire audible spectrum and beyond, essential for catching mix issues before they reach playback systems.
Audio Performance
The 53mm dynamic transducers paired with a 1.5 Tesla magnet system and ultra-lightweight dual-layer voice coil produce an exceptionally wide frequency response extending from 5 Hz to 54,000 Hz. With a sensitivity of 110 dB SPL/V and rated impedance of 36 Ohms, these headphones deliver transparent, detailed sound with a maximum input power handling of 300 mW—sufficient for both sensitive studio equipment and standard consumer devices. The extended upper range lets you identify subtle transients and high-frequency artifacts that shape the character of a mix.
Design & Build
The open-mesh headband and 3D-shaped slow-retention ear pads provide balanced comfort and breathability without clamping fatigue during long tracking and mixing sessions. Detachable ear pads allow for replacement as needed, while the 3-meter oxygen-free copper cable with genuine LEMO connector ensures reliable signal transmission and minimizes impedance coloration in professional studio chains. The included 3.5 mm to 6.3 mm adapter accommodates both consumer interfaces and standard professional gear.

At a Glance
The AKG K812 is a mastering-grade reference headphone engineered for home studios, recording sessions, and critical listening environments where precision and transparency are non-negotiable. The 53mm transducers and 1.5 Tesla magnet system reproduce the full audible spectrum (5 Hz to 54,000 Hz) with neutral tone and spatial accuracy, letting you hear exactly what your mix contains without any tonal character or distortion. Extended comfort through breathable ear pads and an open-mesh headband makes these ideal for long production and mixing sessions where decision-making accuracy depends on hearing every detail.

Frequently Asked Questions
Are these headphones suitable for mixing and mastering, or just critical listening?
The K812 is designed specifically for both mastering and mixing work. The transparent, detailed frequency response from 5 Hz to 54,000 Hz and neutral tone profile deliver the accuracy needed to make critical mixing decisions, while the natural soundstage helps you monitor spatial relationships in your mix.
What makes the open-back design important for studio work?
The open-back design creates a natural soundstage and prevents the enclosed resonance that can mask mix problems. This design choice allows sound to breathe, giving you a more accurate representation of how your mix translates to speakers and other listening environments.
Can I use these with both consumer audio interfaces and professional studio gear?
Yes. The K812 has a 36 Ohm impedance and 110 dB SPL/V sensitivity that works with both sensitive studio equipment and standard consumer devices. The cable includes a 3.5 mm to 6.3 mm adapter to connect to professional and consumer jack standards.
How long can I comfortably wear these during mixing sessions?
The open-mesh headband and 3D-shaped slow-retention ear pads are engineered for extended wear without clamping fatigue. The pads are replaceable, so you can maintain comfort over years of studio use.
What's included in the box and are replacement parts available?
The K812 comes with a 3-meter detachable oxygen-free copper cable with LEMO connector, a 3.5 mm to 6.3 mm adapter, and the headphones themselves. Replacement ear pads are available separately for long-term maintenance.
Do I pay sales tax on this order?
Sales tax is collected only on orders shipped to California; orders shipped to any other US state are not charged sales tax at checkout when you buy direct from our website. At a typical 7% rate that is an estimated $140 less at checkout than the same listed price on a marketplace, which collects sales tax as the facilitator in most states.
