Full-range ultra-linear Driver X
KZ Zenith features the innovative Driver X, a full-range ultra-linear dynamic driver with an increased voice coil diameter. This advancement significantly enhances the driver's acoustic conversion rate by precisely controlling the suspension edge's amplitude efficiency, enabling greater diaphragm excursion, and delivering a broader soundstage and richer high-frequency details. Compared to similar products with a 10mm driver voice coil diameter, Driver X demonstrates a clear advantage in sound quality. Every frequency range, from the deeply impactful bass to the smooth, natural mids and the crisp, bright highs, performs exceptionally, offering a listening experience as if you were on the spot.

Larger Voice Coil Diameter

For broader soundstage and enhanced high-frequency details
KZ Zenith, equipped with the full-range ultra-linear Driver X, features a larger voice coil diameter. This design results in a broader soundstage and richer high-frequency details and significantly enhances overall audio performance. Compared to traditional IEMs with 10mm driver voice coils,  KZ Zenith demonstrates a clear advantage in terms of sound quality. Whether the layering of music or the reproduction of intricate details, it provides a listening experience akin to being present at a live performance.

Precision Magnetic Gap Design

Revolutionary efficiency for flagship performance

Easier to Drive

The magnetic gap of 0.15mm, compared with the common 0.3mm magnetic gap units on the market, has a conversion efficiency in overall performance far beyond comparison with the ordinary magnetic gaps of speakers on the market. The speaker unit can be driven more efficiently by carefully designing the magnetic gap, even with the limited power output of devices like mobile phones. It's not fussy about the devices and can help you easily get high-quality and clear sound.

More Stable Magnetic Field

Meanwhile, improving the magnetic gap helps maintain a relatively stable magnetic field strength within the whole range of the voice coil's movement. In this way, when the voice coil vibrates at different positions, the change in the electromagnetic force it receives is smaller. This enables the speaker to work more linearly within a wider frequency range and improves the frequency response. This is an important part of creating an ultra-linear performance across the entire frequency range because a stable magnetic field allows the speaker to restore sound signals more accurately throughout the whole frequency band from low frequencies to high frequencies, reducing the peaks and valleys in the frequency response caused by an uneven magnetic field.

Lower Distortion

The design of a magnetic gap that is small enough can provide a uniform magnetic field, enabling the voice coil to vibrate smoothly in the magnetic field and reducing sound distortion.

Higher Cost

There are extremely high requirements for materials and manufacturing processes to achieve a very small magnetic gap. For example, suppose the performance of the materials is not good enough. In that case, if the magnet's magnetic property is not stable enough or the winding precision of the voice coil is insufficient, even if the magnetic gap is small, it's impossible to ensure the uniformity of the magnetic field and the stability of the voice coil's movement.

High-Purity Silver-Plated Cable

Upgraded performance as a standard accessory
The silver-plated twin cable has excellent electrical conductivity, and the design of the twin cable further enhances the conductivity. Through the design of reducing electromagnetic interference in the way of twisted pairs, it can reduce the loss of audio signals during the transmission process, thus improving the sound quality performance. In addition, the silver-plated cable has good antioxidant properties, which can greatly extend the service life of headphones. Meanwhile, thanks to the design of the twin cable, the headphones are more convenient to carry and are no longer troubled by wire tangling.
