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 EPZ P40 is 4 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 4 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said

EPZ P40

The EPZ P40 is a wired tribrid IEM that delivers a clean, technically strong sound with excellent midrange presence, controlled bass, and precise imaging for its price. While it shines in resolution and transparency, its tuning can feel sharp or cold to some ears, and it falls just short of class-leading treble refinement. Overall, it's a compelling option under $200 for listeners who value clarity and detail over warmth.

  • Pro:Excellent midrange clarity and vocal presence
  • Pro:Tight, well-defined bass response
  • Pro:Strong technical performance with precise imaging
  • Con:Treble lacks some extension and refinement
  • Con:Tuning may come across as sharp or shouty
  • Con:Limited included eartips

Letshuoer S12

The Letshuoer S12 is a wired planar magnetic IEM that delivers impressive detail, punchy bass, and strong technical performance for its price point. Its tuning leans bright, which enhances clarity but may be too intense for treble-sensitive listeners, and it benefits from a good source and proper eartips to shine. Overall, it's a capable, energetic earphone that offers excellent value under $200, though its soundstage is modest and vocals can come across as slightly lean.

  • Pro:Excellent resolution and note definition
  • Pro:Tight, well-defined bass response
  • Pro:Energetic and engaging tuning
  • Con:Bright treble can be fatiguing for some
  • Con:Vocals may sound a bit thin or lean
  • Con:Average soundstage width
