What reviewers said

Alienware Pro Wireless

Its leatherette pads and moderate 310g weight aim for comfort during long sessions, while the 2.4GHz wireless option and USB-C charging add versatility for desk and on-the-go use. Sound quality is generally strong, but the microphone performance and a single SBC codec limit keep it from being a flawless all-rounder.

  • Pro:Excellent battery life, especially with ANC off
  • Pro:Comfortable leatherette ear pads for long wear
  • Pro:Active noise cancellation and transparency mode included
  • Con:Microphone quality is underwhelming for the price
  • Con:Only SBC codec support limits high-res wireless audio
  • Con:No multipoint connection for seamless device switching
