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 Truthear x Crinacle Zero Red 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

Hidizs Mermaid MS2

The Hidizs Mermaid MS2 is a budget-friendly hybrid in-ear monitor that pairs a 10.2mm dynamic driver with an additional driver for a balanced, coherent sound. Its lightweight resin shell and detachable cable make it a practical daily driver, while its tuning leans toward a lively, detailed presentation that suits energetic music genres.

  • Pro:Lightweight resin shell for comfortable wear
  • Pro:Detachable cable for easy replacement or upgrades
  • Con:Treble can be over-energetic for sensitive listeners
