High-Frequency + Ultra High-Frequency Balanced Armature Array for Unrivaled Sound Detail

KZ ZAT is equipped with brand-new, custom-designed balanced armature drivers, far surpassing the performance of ordinary balanced armature drivers. The second optimization of the 29689 driver further reduces distortion rates, with a 3kHz peak shifting to the right, resulting in a new mid to high-frequency performance level. The third optimization and upgrade of the 30095 ultra high-frequency balanced armature greatly enhance sensitivity response in the ultra high-frequency range, delivering even richer sound details. The powerful super high-frequency array module can output robust sound resolution, providing a much broader soundstage than regular multi-driver earphones.

Truly Super Linear Dynamic Driver

With the support of a four-layer coil, the performance of a single driver surpasses that of other ordinary stacked dual-driver setups. The drop in performance between 20Hz and 100Hz is less than 3dB, ensuring excellent low-frequency depth. The drop between 20Hz and 200Hz is close to 8dB, making the low-frequency response clear, elastic, and incredibly impactful.

Let the Performance Speak!

Breaking the Pricing Mystery - High Price ≠ High Sound Quality
We aim to make music and technological innovation accessible to everyone, proving that high-quality audio doesn't have to come with a high price tag.

Traditional tuning techniques can only control the overall frequency range, often leading to imbalances between the bass, midrange, and treble frequencies. KZ's new patented electronic tuning technology breaks away from tradition by allowing precise control over the entire frequency spectrum.Through this precise electronic tuning technology, we have minimized the drop in sensitivity between 20-100Hz to approximately 3dB. This ensures deep and well-controlled sub-bass frequencies. Simultaneously, we've maintained a sensitivity drop of about 7dB between 20-200Hz, providing the low frequencies with the right amount of punch. Ultimately, this results in an exceptional audio quality that delivers outstanding sound reproduction.

Difference Between Traditional Damping Net and Electronic Filter for Tuning

Traditional damping nets adjust the sound by changing the density of the damping net inside the sound tube's diameter. You need to replace different damping nets to achieve different sounds, which cannot provide precise control over tuning. In contrast, an Electronic filter is a frequency-selective device that filters waves, allowing for precise tuning of specific frequency ranges.
