Vacuum headphones Knowledge Zenith AS12 Black Gold

The AS12 sound extraction scheme is represented by six reinforcing radiators, complemented by a crossover board and an intricate element for linking sound streams together. As for the sound signature of the IEMs, there is a somewhat predictable picture here, as for the Knowledge Zenith product, due to the manufacturer's bet on a moderately V-shaped frequency response, which favorably affects the overall fascination and emotionality of the sound. The bass is reproduced densely, legibly and vigorously, along the way pleasing weightiness and oiliness uncharacteristic for an inexpensive reinforcing sound; mids are played moderately clean, voluminous and expressive, while high frequencies are characterized by sonority, detail and richness of overtones. In conclusion, we should note the AS12's ability to build a spacious and readable stereo panorama, which is typical, as a rule, for headphones, the cost of which is somewhat higher.

The anatomical shape of the cases deserves special attention, thanks to which the headphones are comfortable to listen to even for a long period of time. In addition, due to the presence of elongated sound guides coming out at the right angle, the manufacturer managed to achieve good passive noise isolation.
