QKZ is a brand that offers premium quality Hi-Fi headphones with certified and approved technology from Japan’s Hi-Res association, which provides a sound with great quality low frequency and low distortion.
There are several reasons why you should get any QKZ’s Metal Heavy special edition, the high sensibility, the low distortion and high stability; these are made to capture music’s most subtle details and also to present a more complete musical texture.
For sound lovers, the frequency is a very relevant thing, every beat is highly important when using these headphones. They count with sound cancellation which creates the perfect atmosphere to enjoy sound’s experience with a clear-sky high frequency, mid-frequency just like the quiet hills of Ireland, while the lower frequency is just like insurgent waters.
I highly recommend hearing audio tracks of the highest quality to capture the audio in perfect 4D stereo.
These QKZ models are equipped with an 8mm medium-high dynamic coil unit and a 10mm subwoofer mobile coil unit to achieve three-band high complementation. Intermediate and low frequency, more natural high-frequency stretching, faster and more sensitive intermediate frequency, and more powerful high-frequency shock.
Some of them also feature a dynamic speaker of double unity. Their small exquisite cavity has two dynamic unities to achieve a more beautiful musical texture, offering one of the greatest audio qualities in the market.
All of them have IPX4 level with high impermeability providing them with water-proof protection; if you’re an athlete you should know better than anyone that sweat damages regular headphones. IPX4 technology prevents short circuits with great effectiveness.
Now, if you’re wondering why you should pick a dual headphone driver here’s why: two dynamic different units may work efficiently and each is responsible of representing different music ranges. The sound is more detailed in case it has layers for example. QKZ always searches for excellence which is why the design is worth of consideration.
QKZ stands out for solving the problem of earpieces falling out of the ears; the light design with a total weight of 35 gr Metal bass will be easy to use and comfortable.
In combination with the shape of the atria of human ears, the cavities with water waveforms developed with large ergonomic data can be carried comfortably and naturally. All these thanks to QKZ ergonomic designs.
Also, QKZ Metal bass equipment a built in high definition call MIC that records crystal clear sound and during a call you can notice the difference; they may also have a button control feature in which you can control your mobile device with just some clicks:


  • One-Click: play, pause and answer a call.
  • Double click: move to the next track.
  • Triple-click: move to the previous track.
All models are available in different appealing colours.
