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 Campfire Audio Andromeda 2020 is 2 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.

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: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
