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.
