What reviewers say

Sony WH-1000XM6

  • 4.7 / 5Google Shopping · 4,758 ratings

Reviewers rate the WH-1000XM6 highly, calling its noise cancellation the best available and praising the more expansive, refined sound and improved comfort. CNET scored it 9.2 and named it the top headphone it tested this year. A minority say the sound is merely good for the price and that call noise cancellation falls short.

What people mention
  • Noise cancellationPraisedSeveral reviewers call it the best ANC available and say it silences engine noise and nearby conversations.
  • Sound qualityMixedMost praise the expansive, refined sound and punchy bass, but a few say it is only good for the original retail price.
  • ComfortPraisedThe redesign and stainless steel reinforcement are credited with making long sessions more comfortable.
  • CallsMixedVoice pickup is strong, but some shoppers say ANC does not help on MS Teams calls or meetings.
A reviewer's verdict
  • CNET9.2

    It is the top pair of headphones tested this year, with a redesign for improved comfort, stainless steel reinforcement and upgraded drivers for a more expansive, refined sound.

Questions and answers

Which has better noise cancelling, the Sony WH-1000XM6 or the Marshall Monitor III ANC?
The Sony. Its QN3 processor drives 12 microphones with real-time adaptation, and reviewers call its ANC the best available. The Marshall offers three ANC levels but is a step behind.
Which lasts longer on a charge?
The Marshall. It runs up to 70 hours with ANC on and 100 hours off. The Sony runs about 30 hours with ANC on, though a 3-minute charge gives up to 3 hours.
Is the Sony worth the extra money?
At $295.99 versus $257.99, the Sony buys better noise cancelling, LDAC high-resolution audio and stronger call quality. If battery life and price matter more, the Marshall is the better value.
Which is better for flights?
The Sony. Reviewers praise its performance on flights and its ANC blocks more low-frequency engine noise. The Marshall's longer battery helps on very long trips.
Which is better for calls and meetings?
The Sony. Its six-microphone beamforming system isolates your voice, and you can tap to mute. Some reviewers still find its ANC weak on Microsoft Teams calls.
Do both fold for travel?
Yes. Both fold and ship with a case; the Marshall includes a premium hard case. The Sony lists a carrying case and weighs about 1.5 lb.
