amazon AKG K812 reviews
After the legendary K1000, AKG comes back in the audiophile-headphone line, over $ 1,000, with the K812. The K812’s internal AKG technology is completely new and fully compatible with the price offered.
Until the Sony MDR Z7 is lauched, this was one of the few earphones with the widest frequency range (up to 54kHz), allowing for extremely accurate reproduction of the sound, including theatrical performances.
Still a classic, traditional design, the AKG K812 is received enthusiastically by AKG fans, but also received a lot of criticism in terms of design and finishing. However, the quality of the leather earphones cups is very good, ensuring excellent sound insulation. The metal frame not only shape the headphones, but also help lift the weight, do not make the listener ache when useing for a long time.
The AKG K812 has a headset loudspeaker of up to 53mm in diameter, which maximizes detail and dynamic performance. The AKG K812 has a magnet system of up to 1.5 Tesla, the strongest of today (hi-end headsets usually have less than 1 Tesla). In addition, this is the first time the company develops double voice-coil with aluminum cores, which are coated with copper. The large diameter, powerful magnet and doubel voice-coil combination allows the AKG K812 to operate smoothly in the frequency range up to 54kHz with negligible noise.
