What reviewers said

Audeze Maxwell 2 ANC

No summary yet - we haven't aggregated enough reviews.

STAX SR-Lambda Pro

The STAX SR-Lambda Pro is a vintage electrostatic headphone from 1982 that delivers a neutral, highly detailed sound signature prized by purists. It requires a dedicated electrostatic amplifier, offering exceptional clarity and resolution, but lacks modern conveniences like wireless connectivity or on-ear controls. Its ultra-high impedance demands specialized gear, making it a niche choice for audiophiles with the right setup.

  • Pro:Exceptional detail and resolution for its era
  • Pro:Neutral, accurate tonal balance
  • Pro:Lightweight at 340g for comfortable wear
  • Con:Requires a specialized electrostatic amplifier
  • Con:No inline controls or app support
  • Con:Leatherette pads may not suit all users
