What reviewers said
Campfire Audio Astrolith - Dual Planar IEM
The Campfire Audio Astrolith is a premium dual-planar IEM that delivers a fast, clear, and highly detailed sound with impressive staging and technical precision. Its nearly flat impedance and very low distortion make it a strong performer, though it benefits from quality sources and has a couple of minor ergonomic quirks. Overall, it's a notable step forward in the brand's planar lineup, offering a cohesive and resolving listen for those seeking top-tier wired performance.

- Pro:Very low distortion and flat impedance for consistent performance
- Pro:Wide, well-defined soundstage with precise imaging
- Con:Slight mid-bass bloom can color certain tracks

Westone MACH 80
The Westone MACH 80 is an eight-driver flagship in-ear monitor that delivers a neutral, highly detailed, and linear sound signature, prioritizing accuracy over coloration. Its lightweight, comfortable fit and excellent isolation make it suitable for extended listening, though it truly shines when paired with a capable source or amplifier that can unlock its full technical performance. With a robust accessory package and a 66-ohm impedance, it is built for stability but rewards users with better gear.
- Pro:Exceptional comfort and lightweight design
- Pro:Highly resolving and balanced neutral tuning
- Pro:Excellent treble control and technical performance
- Con:Bass and treble extension are not class-leading
- Con:Can sound flat or underpowered with weak sources
- Con:Demanding of high-quality amplification for best results
