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

KZ PRX (2024) against KZ PR3 (2023). These are 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.

What reviewers said

KZ PR3

The KZ PR3 is a budget-friendly planar IEM that shines in technical performance, delivering crisp detail, wide staging, and precise imaging. Its bright, lean tuning offers speed and clarity but sacrifices bass weight and natural timbre, making it a picky choice for listeners who prefer a warmer, more relaxed sound.

  • Pro:Excellent detail retrieval and resolution
  • Pro:Wide soundstage and strong imaging
  • Pro:Fast, agile planar driver response
  • Con:Bright, peaky tuning can sound harsh or fatiguing
  • Con:Lean bass with limited mid-bass body
  • Con:Timbre can come across as unnatural or metallic

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
