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 Sennheiser HD 400 is 2 years newer, but it is the same generation of hardware: nothing in the radio, the codecs or the noise cancelling separates them. Nothing separates them on convenience features either, so the choice comes down to tuning and price.

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 400

The Sennheiser HD 400 is a wired, open-back over-ear headphone designed for accurate, neutral monitoring at a budget-friendly price. It focuses on natural tonal balance and detail retrieval, making it a solid choice for critical listening and studio work, though it lacks isolation and extra accessories. Its high impedance and lightweight build suit stationary use with dedicated audio gear.

  • Pro:Neutral, transparent sound signature
  • Pro:Comfortable and lightweight for long sessions
  • Pro:Wide soundstage with good detail
  • Con:No carrying case or spare ear pads included
  • Con:Open-back design leaks sound and offers no isolation
  • Con:High impedance may need a stronger source
