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
Westone MACH 40
The Westone MACH 40 is a four-driver balanced-armature in-ear monitor with a warm, smooth, and laid-back tuning that prioritizes comfort and fatigue-free listening over aggressive detail or treble energy. Its 30-ohm impedance and 100 dB sensitivity mean it benefits from a dedicated amplifier to reach its full potential. While it offers a cohesive and natural sound for vocals and acoustics, its recessed mids and intimate stage may not satisfy those seeking high energy or spaciousness. Its solid build and detachable cable make it a reliable choice for long sessions, but it may feel underpowered compared to dynamic-driver rivals in terms of impact.
- Pro:Non-fatiguing, smooth treble that avoids harshness
- Pro:Warm, natural vocal and acoustic reproduction
- Pro:Comfortable fit and detachable cable for durability
- Con:Requires extra amplification due to low sensitivity
- Con:Recessed upper mids can make vocals sound muffled
- Con:Smaller soundstage and less dynamic impact than competitors
