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 Letshuoer S12 Ultra is 2 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.

What reviewers said

Letshuoer DZ4

The Letshuoer DZ4 is a budget-friendly wired IEM that stands out with its unusual triple-dynamic-driver plus passive-radiator setup, offering a neutral-warm and relaxed sound signature. While its build and design are solid for the price, its technical performance—particularly imaging, bass impact, and dynamics—is only average, making it a competent all-rounder rather than a standout in its class. It's an easy recommendation for listeners seeking a safe, flaw-free tuning without aggressive energy.

  • Pro:Unique 3DD + PR driver configuration
  • Pro:Neutral-warm, relaxed tuning that's easy to listen to
  • Pro:Solid build quality for the price
  • Con:Bass impact and dynamics are somewhat lacking
  • Con:Imaging is only average for the price
  • Con:Not class-leading in any specific area

Letshuoer S12 Ultra

The Letshuoer S12 Ultra is a wired in-ear monitor that delivers Hi-Fi sound through a single 14.8mm planar magnetic driver housed in a lightweight aluminum-alloy shell. Aimed at music enthusiasts, it offers the signature planar-driver clarity and detail of the S12 series in a refreshed design, without any active noise cancellation or wireless features. Priced around $169, it's a straightforward, high-performance option for wired listening.

  • Pro:Detailed and fast planar magnetic sound
  • Pro:Lightweight and durable aluminum-alloy build
  • Pro:Accurate bass response with low distortion
  • Con:Requires a wired connection, no wireless freedom
  • Con:No active noise cancellation for noisy environments
  • Con:Open-back style may leak sound in quiet settings
