Generation & platform

The scores rank quality. This is the other question: is the newer one actually newer technology, or the same platform in a new shell?

Same generation

The Alienware Pro Wireless is 8 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. The platform is level; the newer hardware shows up in convenience features instead - the Alienware Pro Wireless adds USB-C and Transparency mode. For 8 years between them, that is a thin return - treat this as a restyle rather than a new platform.

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 559

The Sennheiser HD 559 is a budget-friendly wired over-ear headphone aimed at home listening, offering a warm, bass-forward sound signature with a spacious presentation. It is comfortable and easy to drive, but its tonal balance leans away from neutrality, with subdued highs and a somewhat coarse midrange that may not suit critical listeners. The lack of a 3.5mm adapter and basic cable are notable drawbacks for convenience-minded users.

  • Pro:Comfortable fit for long sessions
  • Pro:Spacious, open soundstage
  • Pro:Easy to drive with most devices
  • Con:Not neutral; bass-heavy with recessed highs
  • Con:Mids can sound coarse or grainy
  • Con:No 3.5mm adapter included
