Sound
Sound: dynamic, balanced armature and electrostatic drivers
Each earpiece houses a 10 mm dual-magnet dynamic driver, a 30095 balanced armature for the treble and a 6.8 mm electret electrostatic driver. KZ highlights the detail and extension of the high frequencies.
With an impedance of 25 Ω and a sensitivity of 104 dB, they run straight from a phone, laptop or music player, with no amplifier needed.
Design
Design and fit
The shell is translucent resin, with a zinc alloy faceplate.
Three sizes of silicone ear tips (S, M and L) are included to get the right seal for each ear.
Connection
Silver-plated flat cable and microphone version
The cable is flat, with two silver-plated 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.
Also available with an in-line microphone.
