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

TWISTURA SIGMA (2025) against KZ PRX (2024). 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 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

TWISTURA SIGMA

A compact wired hybrid IEM that pairs a 6 mm LCP dynamic driver with a custom balanced-armature driver for detailed mids and highs. It includes a USB-C DAC adapter for easy use with phones and other modern devices, making it a versatile budget option for portable listening.

  • Pro:Detailed and clear midrange and treble
  • Pro:Compact, lightweight design
  • Pro:Comes with USB-C DAC adapter
  • Con:No active noise cancellation
  • Con:Requires a source with enough power for best performance
  • Con:Stock cable may be stiff or tangle-prone
