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

Hidizs MS2 PRO (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

Hidizs MS2 PRO

The Hidizs MS2 PRO is a budget-friendly hybrid IEM pairing a 10.2mm dynamic driver with a custom balanced armature for a bass-forward yet technically capable sound. It offers adjustable tuning via included nozzle filters, letting you tweak the response to taste, while its comfortable, well-built shell and detachable cable add everyday practicality. Though engaging and versatile for the price, it has a slightly recessed midrange and can sound bright or sharp in the upper frequencies on certain tracks.

  • Pro:Engaging, bass-forward sound with good impact
  • Pro:Adjustable tuning filters for sound customization
  • Pro:Strong imaging and technical performance for the price
  • Con:Midrange can feel slightly recessed or thin
  • Con:Upper mids and treble may occasionally come across as piercing
  • Con:No wireless or multipoint features, purely wired use

KZ PRX

The KZ PRX is a budget-friendly planar magnetic IEM that delivers impressive clarity, balanced tonality, and solid technical performance for its price. It offers robust sub-bass, smooth mids, and controlled treble, though it demands proper amplification and eartip selection to shine fully. While its soundstage is only medium in size, the overall value remains strong among entry-level planars.

  • Pro:Balanced, warm-U tuning with strong detail retrieval
  • Pro:Good imaging and separation for the price
  • Pro:Robust sub-bass and smooth midrange
  • Con:Requires decent amplification for best performance
  • Con:Stock cable can limit sound quality
  • Con:Soundstage is medium-sized, not expansive
