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 PRO

The LETSHUOER S12 Pro is a wired planar magnetic IEM that delivers fast, detailed, and energetic sound with a V-shaped signature, making it a strong technical performer around the $170 mark. It's easy to drive from most sources, though pairing it with warmer gear can tame its bright treble, and its comfortable fit supports long listening sessions. While its tuning may not suit treble-sensitive listeners, it stands out for its clarity, bass quality, and overall agility in its price range.

Pro:Excellent speed and detail retrieval
Pro:Punchy, well-defined bass response
Pro:Comfortable ergonomics for extended wear

Con:Bright treble can be fatiguing for some
Con:V-shaped tuning may not suit neutral lovers
Con:Benefits from warmer amplification to tame harshness
