Sony WF-1000XM6 Review: Excellent ANC, Familiar Battery

The Sony WF-1000XM6 is for commuters, flyers and people who take a lot of calls outdoors and want flagship noise cancelling in earbuds rather than headphones. The trade-off is value: the improvements over the XM5 are focused on ANC and calls, battery and codecs stay the same, and SoundGuys calls the price high for what changed.

How good is the noise cancelling?

Very good. SoundGuys measured an 88% average reduction in loudness, a step up from the XM5’s 87% and just behind the AirPods Pro 3’s 90%. The biggest gains are in low bass and around 2 kHz, so engine rumble and sharp noises are reduced most. Voices in the 400 Hz–2 kHz range still leak through more than bass, which is typical of earbuds.

How long does the battery last on one charge?

Sony rates it at 8 hours with ANC on and 24 hours with the case. SoundGuys recorded 9 hours 41 minutes in its test, beating the claim. That covers a full workday or a long-haul flight. Quick charging fell a little short in SoundGuys’ test: 3 minutes gave about 45 minutes of playback against Sony’s 60-minute claim.

How does it sound?

SoundGuys gave it a 4.8 out of 5 on its MDAQS sound-quality model and called the stock tuning likely to please most listeners. LDAC is supported for Android phones. Note that the sound changes noticeably when ANC is switched off.

Will it fit my ears?

This is where opinions split. The buds are larger and pill-shaped. SoundGuys found they sealed well and stayed comfortable for hours, but felt slightly top-heavy. T3 found the fit variable and said it will not suit all ears. If you have small ears, try a pair at a Sony Center or Croma store first.

Are calls clear on Indian roads?

SoundGuys rated call quality excellent in quiet rooms and good in wind. On a busy street, loud buses and trucks sometimes broke through the noise suppression, though it still did better than the XM5. For calls from a scooter pillion or a crowded market, it is among the better earbuds, not a miracle.

Any connection problems?

SoundGuys saw occasional dropouts while walking unless it switched the earbuds to prioritise stable connection over audio quality. In crowded metro stations with many Bluetooth devices, expect to use that setting.

What we could not verify

We could not confirm the warranty term Sony India offers on this model, and we found no Indian publication’s long-term owner reports yet, as it went on sale only in August 2026.

Should you buy it?

If you want the best noise cancelling and calls in earbuds and your budget allows it, yes. If you already own the WF-1000XM5, the upgrade is small.
