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

Binary Acoustics Gizaudio × Chopin

This hybrid IEM combines an 8 mm ceramic dynamic driver with three balanced-armature drivers, delivering a versatile sound signature that adapts easily to various music styles. With a low 12-ohm impedance, it's highly sensitive and pairs well with most portable sources, making it a flexible choice for everyday listening at its price point. The tuning prioritizes balance and musicality over analytical precision, appealing to those who want an all-rounder without a specific genre bias.

  • Pro:Well-balanced tuning that suits multiple genres
  • Pro:Compact 8 mm ceramic driver offers fast, punchy bass
  • Pro:Low impedance makes it easy to drive from any device
  • Con:No noise isolation or ANC, so background noise can intrude
  • Con:Some might find the tuning too safe or inoffensive
  • Con:Higher sensitivity could reveal hiss on noisy sources

Letshuoer S12 Ultra

  • Pro:Fast, detailed planar sound with strong dynamics
  • Pro:Lightweight and sturdy aluminum-alloy build
  • Pro:Easy to drive thanks to low impedance
  • Con:No noise cancellation or isolation features
  • Con:Planar timbre may not suit all listeners
