What reviewers said

Audio-Technica Ad2000x

The Audio-Technica AD2000X is a lightweight, open-back over-ear headphone designed for high-fidelity listening, featuring a 53mm dynamic driver and an impressively wide frequency response. It is built to be easily driven and offers a balanced connection, though it lacks active noise cancellation and USB-C compatibility. The sound is described as detailed, lush, and organic, with tight bass, but the open-back design means it offers no isolation and it may not be as comfortable as its predecessor.

  • Pro:Lightweight design at 265g
  • Pro:Wide frequency response from 5 Hz to 45 kHz
  • Con:No active noise cancellation
  • Con:Open-back design offers no sound isolation
