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

Sennheiser HD 450BT

The Sennheiser HD 450BT are wireless over-ear headphones that deliver a balanced, neutral sound and solid active noise cancellation for their price point. They offer a long 30-hour battery life with quick USB-C charging, though comfort may vary due to smaller ear cups and the build feels a bit plasticky. Overall, they're a competent budget pick, but not top-tier in any single area.

  • Pro:Balanced, neutral sound
  • Pro:Effective noise cancellation for the price
  • Pro:Long 30-hour battery life
  • Con:Ear cups can feel small and uncomfortable over time
  • Con:Build quality feels somewhat flimsy
  • Con:Call quality is mediocre
