Generation & platform
The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?
Same generation
The KZ PRX is 3 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price. For 3 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said
KZ PRX
The KZ PRX is a budget-friendly planar magnetic IEM that offers a balanced, warm-leaning sound with strong detail retrieval and capable imaging for its price. It excels in sub-bass presence and smooth mids, though it demands proper amplification and ear tips to perform at its best. Its soundstage is decent but not exceptionally wide, and the stock cable is a noted weak point.
- Pro:Excellent value for a planar IEM
- Pro:Balanced, warm sound with good detail
- Pro:Strong imaging and separation for the price
- Con:Requires a capable source and good ear tips
- Con:Stock cable limits performance
- Con:Soundstage is only medium-sized
KZ ZAS
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.
- Pro:Energetic and engaging bass response
- Pro:Clear and detailed mids and treble
- Pro:Comfortable, lightweight build
- Con:Stock tuning may be too V-shaped for purists
- Con:Lacks active noise cancellation
- Con:No app support or custom EQ options
