The new K812 reference headphones are an open-back design with oversized 53-mm drivers claimed to have the highest dynamic range ever for an AKG headphone.
Each K812 is built for comfort with a fast, adjustable headband and extremely soft earpads to ensure comfort. Although they cannot be folded up, AKG uses a cardan or universal joint system for the individual L/R earpieces so they freely adapt to your head and ear’s shape.
The two-layer, copper-covered aluminum voice coil and new magnet system measuring 1.5 tesla units extends the K812’s operating range from 5Hz up to 54kHz—beyond the limits of human hearing. They are capable of handling about a 1/3-watt of power, have a sensitivity of 110 dB SPL/V, come with a detachable/replaceable cord with gold screw-on adapter and weigh about 390 grams.
