Know before you buy
While designed for professional studio monitoring, the K812’s expansive soundstage and detailed frequency response make them excellent for critical listening at home. Keep in mind that their open-back design leaks sound, so they are best suited for quiet environments.
With an impedance of 36 Ω and a sensitivity of 110 dB SPL/V, these headphones are relatively easy to drive. However, to fully realize their potential for precise imaging and bass control, pairing them with a high-quality DAC or amplifier is recommended.
The open-back construction allows air to move through the ear cups, which prevents pressure buildup and creates a wider, more natural soundstage. This design provides a 'speaker-like' listening experience, though it offers no isolation from external noise.
The K812 features unique asymmetrical ear pads designed to conform to the shape of your head for a secure, comfortable fit. While they are built for durability, they are replaceable to ensure the headphones remain comfortable over years of professional use.
The headphones utilize a detachable, high-purity oxygen-free cable that connects to the unit via a professional-grade LEMO connector. This ensures a secure, reliable connection that is standard in high-end studio equipment.
The K812 is known for a fast, clean, and accurate bass response rather than an emphasized or 'boomy' profile. It provides a tight, articulate low end that reveals detail without bleeding into the mid-range frequencies.
