KZ AS16 Pro X: 16 balanced armature in-ear monitors for the rehearsal room and the stage
The KZ AS16 Pro X are wired in-ear monitors designed for musicians who want to hear themselves clearly in rehearsal and on stage. They use balanced armatures only: eight per earpiece, 16 in total, split by frequency. They have a metal frame with a clear resin faceplate, are worn with the cable over the ear so they stay put while you play, and the flat silver-plated 2-pin cable is detachable: if it breaks, you replace the cable, not the earphones.
Because they sit inside the ear they isolate you from the noise of the rehearsal room, so you don't have to turn the volume up as much to hear your voice or your instrument. They plug into an IEM bodypack, the headphone output of the mixing desk or your phone through a 3.5 mm jack, and there is also a version with a USB-C cable. Available in black, with or without a microphone.

Drivers
Sound: 8 balanced armatures per side
Each earpiece houses eight balanced armatures split by frequency: four 31736 for the treble, one 30019 for the upper mids, two 29689 for the mids and one 22955 for the bass.
With an impedance of 19 Ω and a sensitivity of 116 dB (±3), they run straight from a phone, laptop or music player, with no amplifier needed.
Construction
Design and fit
The frame is metal and the faceplate is carved clear resin.
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 and silver-plated, and measures 120 cm (±5 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.
The microphone version adds an in-line remote to play or pause, skip tracks and take calls.
Wireless mode with a Bluetooth adapter is for listening to music; to monitor yourself while you play, use the cable, which has no latency.

KZ AS16 Pro X frequently asked questions
Can they be used as in-ear monitors for playing live or in the rehearsal room?
Yes. Worn with the cable over the ear and with the right ear tip size, they isolate you from the noise of the rehearsal room. The usual setup is to plug them into an IEM bodypack that receives a send from the mixing desk, so each musician gets their own mix; you can also plug them into the headphone output of the desk.
And for listening to music or gaming?
Yes. Although we recommend them mainly for playing, they work just as well for listening to music on your phone or computer and for gaming, and the microphone version lets you take calls. Wired, there is no latency.
Do the KZ AS16 Pro X have noise cancellation?
They have no active noise cancellation. They are in-ear earphones with silicone ear tips, which passively block outside noise by sealing the ear canal.
Do they work with phones that have no headphone jack?
Yes, with a USB-C or Lightning to 3.5 mm jack adapter, or with a 0.75 mm 2-pin Bluetooth adapter. There is also a version with a USB-C cable.
Can the cable be replaced?
Yes. The cable is detachable and uses a standard 0.75 mm 2-pin connector.
What warranty do they come with?
3-year warranty against manufacturing defects, handled from Spain.
