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

Both shipped in 2025. 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

Kiwi Ears Astral

The Kiwi Ears Astral is a hybrid wired IEM that blends a dynamic driver with six balanced armatures, delivering a bass-forward yet detailed sound with smooth highs and a natural midrange. While it offers strong clarity, good instrument separation, and a comfortable fit for many, its large shells may cause fatigue over long sessions, and the mid-bass and lower midrange could feel leaner than some listeners prefer. Overall, it's a well-rounded performer in the $300 range, though not perfectly neutral due to its elevated low end and relaxed treble.

  • Pro:Deep, impactful sub-bass with good control
  • Pro:Clear and detailed treble without harshness
  • Pro:Natural midrange with good instrument separation
  • Con:Large shells may reduce comfort during extended listening
  • Con:Limited included eartip selection
  • Con:Mid-bass punch and lower midrange can seem thin

Moondrop HARMON XTM-3DD

This wired in-ear monitor packs three 10mm dynamic drivers into a coaxial, four-chamber layout to split frequency duties, with one driver covering mids and highs while a duo handles low-end punch. It's a bass-forward, no-frills design for listeners who want physical impact without active noise cancellation, priced at around $350.

  • Pro:Triple-driver dynamic setup for robust, layered sound
  • Pro:Coaxial design helps with coherent imaging
  • Pro:Detachable 0.78mm two-pin cable for easy replacement
  • Con:No active noise cancellation, so isolation depends on fit
  • Con:Large driver count may make the shell bulky
  • Con:Bass-heavy tuning might not suit neutral purists
