24 Balanced Armature IEM

The KZ AST in-ear monitor houses twelve balanced armature drivers per side for a total of twenty-four units. A silver-plated cable with two-hundred cores per strand aims to reduce signal loss and distortion. The package includes a detachable 0.75 mm 2-pin connector and a 3.5 mm plug for wired connectivity.

Musicians and critical listeners

The ergonomic zinc alloy and resin shells provide passive noise isolation and a secure ear-hook fit for stage or studio monitoring. An optional inline microphone is available for communication. Buyers who require wireless freedom or active noise cancellation should consider a different form factor.

Detachable cable integration

The replaceable cable uses a standard 0.75 mm 2-pin interface so users can swap leads without replacing the earpieces. A 125 cm length offers enough reach for desktop or mobile sources. The 30 ohm impedance and 103 dB sensitivity allow efficient driving from portable players without a dedicated amplifier.

Questions about this item

Does the 3.5 mm plug connect directly to my phone or do I need an adapter?

The KZ AST uses a standard 3.5 mm plug, so it works with any device that has a 3.5 mm headphone jack. If your phone lacks that jack, you will need a separate USB-C or Lightning to 3.5 mm adapter.

Will the 0.75 mm 2-pin cable work with the older KZ cables I already own?

Yes, the AST uses the common 0.75 mm 2-pin connector, so it is compatible with existing KZ cables that share the same pin spacing and polarity.

How can I confirm the 24 balanced armature drivers are functioning correctly after I plug them in?

Play a frequency sweep from 10 Hz to 40 kHz; you should hear smooth output across the range with no dropouts, and the 103 dB/mW sensitivity means normal listening volumes are reached at very low source levels.
