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

DUNU Zen Pro (2021) against Campfire Audio Andromeda 2020 (2020). 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

Campfire Audio Andromeda 2020

The Campfire Audio Andromeda 2020 is a premium five-driver balanced armature IEM that refines the original's signature with smoother, more coherent mids and improved treble. It delivers an expansive soundstage with excellent imaging and layering, though its low impedance and high sensitivity mean it demands a quality source to shine. A worthwhile update for both newcomers and existing fans, it excels in clarity and detail but has some limitations in bass texture.

  • Pro:Cohesive and smooth midrange
  • Pro:Excellent soundstage and imaging
  • Pro:Strong, detailed treble
  • Con:Requires a high-quality source
  • Con:Limited bass texture and weight
  • Con:No controls or ANC

DUNU Zen Pro

The DUNU Zen Pro is a premium single-dynamic-driver IEM that trades the original Zen's darker tuning for a more neutral, balanced sound while keeping excellent build quality and a generous accessory kit. Its 13.5mm driver delivers textured bass and smooth treble extension, though its fit can be picky with eartips and its sub-bass impact is more restrained than its predecessor. Priced around $900, it's a well-rounded wired option for those prioritizing clarity over punch.

  • Pro:Excellent build quality and comfortable fit
  • Pro:Neutral, well-balanced tuning with good treble extension
  • Pro:Rich bass texture and layered microdynamics
  • Con:Fit is sensitive to eartip choice
  • Con:Sub-bass rumble is muted
  • Con:Bass slam is less forceful than the original Zen
