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 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.

  • Pro:Warm, enjoyable tuning
  • Pro:Detachable 0.78 mm 2-pin cable

Moondrop CHU II

The Moondrop CHU II is a budget-friendly wired IEM that builds on its predecessor with a more comfortable fit, a detachable 2-pin cable, and a satisfyingly warm yet detailed sound signature. Its 10mm dynamic driver is easy to drive and offers strong performance per dollar, making it a solid entry point for newcomers, though its compact shell can feel slightly weighty and isolation is only average. The tuning leans toward fun with punchy bass, but the treble can occasionally edge into brightness on certain recordings, and the soundstage remains on the narrower side.

  • Pro:Comfortable and improved fit over the original
  • Pro:Removable 0.78mm 2-pin cable adds longevity
  • Pro:Engaging bass-forward tuning with good detail
  • Con:Treble can become bright or harsh on some tracks
  • Con:Soundstage is relatively narrow
  • Con:Slightly heavy build for an IEM
