The KZ ZS1 Dual-Driver Extra Bass In-ear Earphones


The 8mm bass boost driver and 6.8mm treble driver, vigorous of each frequency

Usually any single speaker cannot reproduce the sound of each frequency flawlessly. The KZ ZS1 achieves a good performance of treble, midrange and bass with the help of the dual-driver design.

Valve independent sound channel

The two drivers in the same housing can easily cause sound wave interference. The KZ Audio made an improvement with the ZS1 that's unique compared to ordinary dual driver headphones. ZS1's independently built sound channels for each driver reduces sound wave interference thus maintaining a pure and balanced audio.

Ingenious frequency divider

The frequency divider separates input signals into bass and treble with a corresponding driver. This allows the drivers to maximize its potential per input signal. Frequency response is more smooth, acoustic image is more accurate. Creates a balanced harmony with broad and natural audio output.
