Sound
Sound: 12 mm dynamic driver and electrostatic driver
Each earpiece houses a 12 mm dynamic driver for the bass and mids and a 6.8 mm electrostatic driver for the treble. KZ highlights the bass power and the clarity of detail.
With an impedance of 32 Ω and a sensitivity of 113 dB, they run straight from a phone, laptop or music player, with no amplifier needed.
Design
Design and fit
The shell is metal.
Three sizes of silicone ear tips (S, M and L) are included to get the right seal for each ear.
Connection
Detachable silver-plated 2-pin cable
The cable is high-purity silver-plated, with 8 cores, and measures about 120 cm.
It attaches to each earpiece with a standard 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
Microphone version
The microphone version adds an in-line remote to play or pause, skip tracks and take calls.
The version without a microphone is identical in sound and build.
