Hi-Res High-resolution audio standards up to 40 kHz give you the ability to capture subtle sounds from the subtle timbre of musical instruments to the shallow singing of lyrics. The latest high-quality music standard proposed by Sony in 2014 is Hi-Res. The highest sampling frequency is 92Khz/24bit. A higher bit depth means a richer description of sound, as well as being more transparent.

A precise control of the air flow, carried out through many tests and acoustic calculations, ensures that the dynamic coils' full vibration unites powerful analytical forces and generates an annoying noise.

Each part of the QKZ VK4 is built using industry-recognized cutting-edge materials and processes, ensuring professional results and excellent sound quality at every cost.

The Tesla magnetic circuit design provides stronger detail reproduction and dynamic performance than traditional moving coil units, making the sound more natural and mellow.

The graphene diaphragm movable coil, light and strong rigidity and toughness make the diaphragm range wide, enable excellent transient responses, and enhance high and low tone ductility

The patented dual magnetic bisector unit has a strong driving force, quasi-Tesla unit (gap flux reaches 0.9-10 Tesla) has a significant improvement in electro-acoustic efficiency compared with the ordinary driving unit, the cavity is larger, Which is equivalent to increasing the linear space of the unit, and the sound is more natural by adjusting the size of the rear cavity and the air permeability coefficient, the low and intermediate frequency response can be significantly improved, the sound is smooth and the sound field is wide. Acoustic guide holes are arranged on the back of the driving unit to control the size of the guide holes are arranged on the back of the driving unit to control the size of the guide holes reasonably, Optimize the transient characteristics of vibration film motion to raise the bass, and accurately reproduce the rhythm of each frequency point.

Deduce on actual Strength amazing wide Sound field and vivid live experience. Detailed tuning makes independent voice movement circle both Stable bass and clear human voice.

Integrating the big data of ear mould through the ingenious design of ergonomics, will enter the eartype and the ear type. The combination of ear-hanging Style, even in the fierce sports, Wear is still solid and burden-free.

Bluetooth module can be replaced independently and upgraded to Bluetooth headset. Silver-plated wire can be replacement independently to improve the quality of earphone music.

Imported TPE material Skin, high toughness and tensile resistance, 99.99% multi-core high purity copper cables, can produce low-frequency condensed mellow thickness and hierarchical high-frequency, forming a deep sense of space.

3.5mm universal pin design, gold-plated plug has stronger sensitivity, can reduce the loss of signal transmission, ensure high definition and non destructive transmission of sound quality.
