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

KEF Mu7

The KEF Mu7 are over-ear wireless headphones with adaptive noise cancellation and a robust 40-hour battery life, even with ANC active. They offer broad codec support including aptX HD, multipoint Bluetooth 5.1, and a comfortable build, though sound character and feature set may divide opinion. Their performance leans toward a neutral, hi-fi presentation, but they lack some modern conveniences like transparency mode or EQ adjustments. Overall, they're a solid, if not class-leading, option for long-listening sessions with adaptive ANC.

  • Pro:Excellent 40-hour battery life with ANC on
  • Pro:Adaptive noise cancellation for changing environments
  • Pro:Broad codec support including aptX HD and AAC
  • Con:Sound can feel bland or lacking in dynamics
  • Con:No transparency mode for quick ambient awareness
  • Con:Limited control options and no custom EQ
