What reviewers said

64 Audio Volür

The 64 Audio Volür is a premium hybrid IEM that delivers a powerful, bass-forward sound with impressive dynamics and technical performance. It offers tuning flexibility through its Apex modules, making it a versatile choice for listeners who prioritize low-end impact while still wanting good clarity and detail. However, its bright upper treble can be polarizing, and the included cable doesn't match the quality of the earphones themselves.

  • Pro:Powerful, tight, and dynamic bass response
  • Pro:Excellent imaging and a spacious, three-dimensional soundstage
  • Pro:Tuning flexibility via swappable Apex modules
  • Con:Upper treble peak may be harsh for sensitive listeners
  • Con:Cable quality is underwhelming for the price point
  • Con:Tuning in upper mids and treble can be divisive

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:Exceptional speed and clarity across the frequency range
  • 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
  • Con:Stock ear tips are not very good and may need replacement
  • Con:Best results require a high-quality source or amplifier
