Sound
Sound: super-linear dynamic driver
Each earpiece houses a single dynamic driver that KZ calls super-linear. According to the manufacturer, its internal structure lowers distortion and widens the dynamic range, with good detail resolution and punchy bass.
With an impedance of 23 Ω (±3) and a sensitivity of 108 dB (±3), they run straight from a phone, laptop or music player, with no amplifier needed.
Design
Design and fit
The shell combines clear resin with a metal faceplate; it is light and tough. The shape is ergonomic and the cable has ear hooks that route it behind the ear.
Three sizes of silicone ear tips (S, M and L) are included to get the right seal for each ear.
Connection
Detachable flat 2-pin cable
The cable is flat oxygen-free copper and measures 120 cm (±5 cm). The flat design reduces tangling.
It attaches to each earpiece with a standard gold-plated 0.75 mm 2-pin connector, so it can be replaced if damaged or swapped for another cable. The same connector lets you go wireless with a KZ Bluetooth adapter that is compatible.
Versions

The microphone version adds a microphone and a single-button in-line remote:
- Single press: play or pause, and answer or end a call.
- Double press: next track.
