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

HiFiMAN RE400i (2024) against Truthear x Crinacle Zero Red (2023). 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

HiFiMAN RE400i

The HiFiMAN RE400i is a lightweight, wired IEM that delivers a smooth, balanced, and detailed sound signature, making it a strong value for budget-conscious listeners who prioritize clarity over bass punch. Its compact fit and comfortable design are complemented by a decent accessory set, though the build quality—especially the cable—is a notable weak point. Best suited for acoustic, classical, or critical listening, it lacks modern extras like app support or a robust remote.

  • Pro:Accurate, detailed midrange and treble
  • Pro:Neutral, non-fatiguing tuning
  • Pro:Very lightweight and comfortable
  • Con:Bass is restrained and lacks impact
  • Con:Cable is thin and feels fragile
  • Con:No app support or advanced features

Truthear x Crinacle Zero Red

This wired in-ear monitor pairs a 10 mm and a 7.8 mm dynamic driver in a dual-driver setup, tuned for a warm, natural sound signature. It’s designed to be comfortable for extended listening, making it a solid pick for those who prefer a relaxed, non-fatiguing presentation. With no ANC, it relies on passive isolation from its fit.

  • Pro:Warm, natural tuning for long sessions
  • Pro:Dual dynamic drivers for rich bass and detail
  • Pro:Comfortable fit for extended wear
  • Con:No active noise cancellation
  • Con:Requires a source with enough power (17.5 ohm impedance)
  • Con:Bulky shell may not suit small ears
