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 FiiO FX17 is 7 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 7 years between them, that is a thin return - treat this as a restyle rather than a new platform.

What reviewers said

FiiO FX17

  • Pro:Swappable plugs on the cable provide flexible connectivity
  • Con:No active noise cancellation, requiring a quiet environment or isolation tips
  • Con:High price point may limit accessibility
  • Con:16-ohm impedance may need a powerful source for optimal performance

Letshuoer EJ07

The Letshuoer EJ07 is a wired tribrid in-ear monitor that delivers strong technical performance, particularly in separation and layering, with a clean, resolving character that suits vocals and guitars. Its tuning leans clinical and specialized, with a lighter sub-bass and subdued highs, which may not appeal to all listeners. While it excels in clarity and detail, its high price and some cable quirks make it a niche choice rather than a universal recommendation.Pros: ["Excellent separation and layering for complex tracks", "Resolving and detailed treble extension", "Clean, well-defined midrange for vocals and guitars", "Solid build quality with a premium feel"], "cons": ["Clinical tuning that may lack warmth", "Sub-bass presence is limited", "Treble can sound subdued or rolled-off", "High asking price relative to overall value"]}
