AKG K872 Master Reference Closed-Back Headphones — B-Stock
The AKG K872 stands as the industry standard for critical monitoring in live sound, studio tracking, and live mixing applications. Built from nearly 70 years of AKG engineering, these headphones deliver the precision imaging and dynamic range that engineers and sound technicians depend on for mixing monitors, tracking cues, and demanding field work. The closed-back design provides excellent isolation—essential for getting accurate cues on stage or in the truck—while the open-mesh headband and 3D-shaped slow-retention foam earcups stay comfortable through long nights of monitoring and troubleshooting.
Audio Performance & Transducers
Custom 53mm drivers with 1.5 Tesla magnet systems deliver exceptional headroom for precise imaging, authoritative low frequencies, and extended dynamic range. A two-layer copper-covered aluminum voice coil enables the extended 5 Hz to 54 kHz frequency response, while THD below 0.1% at 1kHz ensures transparent, artifact-free monitoring across the full spectrum.
Build Quality & Road Reliability
Robust metal construction and a demanding factory test regimen ensure reliable operation in touring rigs, live venues, and mobile mixing setups. The 3-meter removable cable features a precision LEMO connector, gold-plated miniplug, and included 1/4" TRS adapter for seamless integration into any mixing console or monitoring system, while the included carrying case protects the headphones during travel between gigs.
