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 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

Blon BL03

The Blon BL03 is a budget-friendly wired IEM that delivers a warm, engaging sound with solid bass and natural timbre for its price. However, its fit can be tricky, often requiring aftermarket tips or cables to achieve optimal performance and comfort.

  • Pro:Excellent value for the price
  • Pro:Natural and dynamic sound
  • Pro:Good bass response
  • Con:Fit can be problematic
  • Con:Stock cable and tips are subpar
  • Con:Isolation is below average

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
