Knowledge Zenith ZAX

Unusual vacuum headphones with interchangeable cables and the ability to connect wirelessly using an external Bluetooth adapter. Like all products of the Knowledge Zenith (or simply KZ) brand, this model is aimed at hardcore music lovers who, on the one hand, do not need the advanced capabilities of TWS models, and, on the other hand, are not ready to sell a kidney for expensive audiophile headphones.

The KZ ZAX model is really capable of surprising: a complex speaker of its own design with a double magnet, one dynamic driver and seven (!) reinforcing radiators, where each one is responsible for its own frequency range, is responsible for sound reproduction. The speaker has a total sensitivity of 113 dB and is able to reproduce the frequency spectrum from ultra-low 20 Hz to frequencies almost inaudible to the human ear in the region of 40 kHz.

And to reduce the influence of external factors on the sound, KZ engineers equipped each earpiece with a zinc faceplate and a compensation hole. Thanks to this, the model boasts an excellent sound, as for its price range, with a well-accentuated bass, a neat midrange and transparent high frequencies. Not without reason, some bloggers compared their sound with the legendary Kinera Idun.
