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

EPZ P40 (2026) against TANCHJIM SODA (2025). 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

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

TANCHJIM SODA

This wired hybrid earphone pairs a 10mm dynamic driver with four balanced-armature drivers and a couple of passive radiators to deliver an open, detailed sound for everyday hi-fi use. It's a multi-driver design aimed at clarity and airiness rather than heavy bass or noise isolation. The 0.78mm two-pin connector and low 15.5-ohm impedance make it easy to drive with most sources.

  • Pro:Airy, detailed treble and vocals
  • Pro:Hybrid tuning offers good separation
  • Pro:Lightweight, comfortable fit for long sessions
  • Con:No noise cancellation or isolation
  • Con:Bass may feel light for bassheads
  • Con:Requires a quality source to shine fully
