Hybrid driver IEM

The KZ ZSN Pro X is a wired in-ear headphone that pairs one balanced armature with a 10 mm dynamic driver. Zinc alloy faceplates and resin cavities give a durable, ergonomic shell. A detachable 1.2 m cable with reinforced pin protection allows easy replacement. Supplied with three pairs of ear tips and a microphone-equipped inline control.

Wired listeners wanting replaceable cables

Buyers who prefer a single-cable solution with volume control on the wire will not find it here; the inline remote handles playback and calls only. Wireless convenience seekers should look elsewhere because the 3.5 mm connector requires a physical jack. The optional microphone means some units ship without one, so confirm before purchase if voice chat is essential.

25 ohm impedance and 112 dB/mW sensitivity

These electrical parameters decide whether a source can drive the earphones to adequate volume without distortion. Low-output portable players and smartphones typically match well, while very high-impedance dedicated amplifiers may not be necessary. The 7 Hz to 40000 Hz frequency response range follows from the hybrid driver topology.

Questions about this item

How long will the detachable 3.5 mm cable last before I need to replace it?

The cable uses a slot-protection design that guards the pins against breakage, and because it is detachable you can swap in any compatible IEM cable when wear eventually appears.

What limits listening volume during extended sessions with the 25 ohm, 112 dB/mW drivers?

The low 25 ohm impedance and high 112 dB/mW sensitivity mean a phone or portable player drives them loudly with little power, so the practical limit is the source device's maximum output rather than the earphones themselves.

How much heat or noise do the hybrid 10 mm dynamic driver and balanced armature produce after hours of use?

Passive drivers generate no electrical noise or noticeable heat; the only sound leakage is what escapes the seal, and the zinc-alloy shell stays at ambient temperature during all-day listening.
