The KZ ZAS is a 16-unit hybrid flagship earphone combining a 10mm dual magnetic dynamic driver with multiple balanced armatures for detailed sound. It features an ergonomic design, a 200-core silver-plated cable, and an exchangeable 2-pin cable for optional Bluetooth use.

The HearWiki takeAI-condensed

The KZ ZAS is a budget-friendly hybrid IEM that pairs a dynamic driver with seven balanced armatures for a lively, detailed sound. It offers a fun, bass-forward tuning that many will enjoy straight out of the box, with a comfortable and well-constructed shell. While its stock tuning may not suit everyone, it remains a versatile performer for the price.

What works

KZ ZAS Review - 16 Driver Hybrids

Vortex Reviews10.5K viewsOct 2021

The reviewer finds the KZ ZAS to be a well-built and comfortable hybrid IEM with a prominent, bass-heavy sound that suits bass lovers and fun listening, though the excessive low end and a forward 2kHz peak in the female vocal range are drawbacks. They appreciate the safe, detailed treble and easy drivability, and suggest EQ to tame the bass and 2kHz for a more balanced signature. Overall, they consider it a good product and prefer it slightly over the ZAX.
