Description
KZ ZST X PL
A hybrid in-ear monitor pairing a double-magnetic 10mm dynamic driver with a 30095 balanced armature, wrapped in a 100-core high-purity silver-plated cable - the direct successor to KZ's breakout ZST.

Why You'll Love It
A hybrid in-ear monitor pairing a double-magnetic 10mm dynamic driver with a 30095 balanced armature, wrapped in a 100-core high-purity silver-plated cable - the direct successor to KZ's breakout ZST.
The Successor To A Legend
A Cable That's Actually Upgraded
Two Drivers, Clearly Divided Work
The KZ Standard
KZ (Knowledge Zenith) is a Chinese in-ear monitor specialist founded in 2008 in Dongguan by Keith Yue, a former Audio-Technica engineer, and Zen Li, a Western-trained classical musician. What began as a Taobao storefront in 2010 became a formally promoted brand in 2013, and KZ's breakthrough moment came in 2016, when its ZST model sold 10,000 units in 15 days. The company has since shipped to 128 countries and become one of the most recognized names in budget-to-midrange in-ear monitors, known for packing genuine multi-driver hybrid configurations into affordable earphones rather than relying on a single dynamic driver.
Engineered With Purpose
A Balanced Armature Built For The Highs
The 30095 balanced armature is dedicated to high-frequency detail, working alongside the dynamic driver rather than trying to cover the full range alone.
A Double-Magnetic 10mm Dynamic Driver
The double-magnetic dynamic unit handles bass and mids, crossed over with the balanced armature above so each driver only has to do what it's actually good at.
A Cable That's Actually Upgraded
A 100-core high-purity silver-plated cable is a genuine step up in strand count over a basic silver-plated cable, for better durability and reduced signal loss - detachable via a 0.75mm 2-pin connector.

Krila and ZST X both use the same core 1DD+1BA hybrid layout, but Krila adds an onboard 4-level tuning switch for hands-on adjustment, while ZST X keeps things simpler with a fixed tuning and leans on its colorway-forward transparent shell and upgraded cable as the differentiators.
