Sony WH-1000XM6 Six-Month Review: Still the ANC King?

Six months ago, Sony released the WH-1000XM6, the latest in their iconic noise-cancelling headphone line. We published our initial review within two weeks. Now, after six months of daily use across flights, offices, commutes, and home listening, we have a much clearer picture of whether these headphones justify their $400 price tag.

What Held Up

Noise Cancellation: Still Best in Class

After testing the XM6 against the Bose QuietComfort Ultra, Apple AirPods Max, and Sennheiser Momentum 4 over six months, the Sony WH-1000XM6 maintains its ANC crown. The Adaptive Sound Control feature, which automatically adjusts ANC based on your activity and environment, has gotten smarter with firmware updates. It now transitions between modes more smoothly and reacts faster to environmental changes.

On a recent cross-country flight, the XM6 eliminated engine drone so completely that we had to check whether the engines were still running. Low-frequency noise cancellation remains unmatched.

Battery Life: Consistent and Reliable

Sony claims 30 hours with ANC enabled. After six months, we consistently get 27-29 hours between charges. Battery degradation has been negligible. The quick-charge feature (three hours of playback from a five-minute charge) has saved us multiple times before flights and meetings.

Multipoint Bluetooth: Seamless

The ability to connect to two devices simultaneously is not new, but the XM6 handles it better than its predecessors. Switching between laptop and phone is nearly instant — under one second in our experience. This matters for anyone who takes calls on their phone while working on a laptop.

What Didn't Hold Up

Comfort During Long Sessions

In our initial review, we praised the comfort. After six months, we have a more nuanced view. The XM6 is comfortable for two to three-hour sessions. Beyond four hours, the clamping force creates pressure points above the ears. The ear cushions are softer than the XM5, but the headband padding compresses with extended wear.

We found that taking a five-minute break every two hours resolves the issue completely, but users who need all-day wear should consider the lighter Bose QuietComfort Ultra, which distributes weight more evenly.

The Touch Controls

Sony's touch panel on the right earcup works well in controlled environments. In cold weather with gloves, or with wet hands after washing, the touch controls become unreliable. Physical buttons would be more consistent. The Bose QC Ultra uses physical controls and we have come to envy that design choice.

The Carrying Case

The included case is too bulky. At roughly 8 inches across, it takes up significant bag space. The XM5's case was slimmer because the headphones folded flat. The XM6 only folds inward, not flat, resulting in a larger case. This is a daily annoyance for commuters and travelers.

Sound Quality After Break-In

Whether headphone "burn-in" is real or psychological is debated. What we can confirm is that our subjective experience of the XM6's sound has improved over six months. The bass feels tighter and less boomy than it did out of the box. The midrange clarity has become our reference point for evaluating other headphones.

With the EQ settings dialed in through the Sony Headphones Connect app, the XM6 sounds exceptional across genres. The LDAC codec support delivers genuinely high-resolution audio from compatible Android devices.

For iPhone users, the sound quality difference versus the Apple AirPods Max is marginal since both are limited to AAC on iOS.

Six-Month Durability

The headband shows no signs of wear. The ear pads have maintained their shape and feel. The hinges remain tight. The carrying case zipper is smooth. Sony's build quality on the XM6 is excellent.

One concern: the matte finish on the earcups attracts fingerprints and shows minor scratches. A carrying case is essential.

The Verdict After Six Months

The Sony WH-1000XM6 remains the best all-around ANC headphone you can buy. The noise cancellation is unmatched, the battery life is excellent, and the sound quality rewards critical listening. The comfort issue during extended sessions and the bulky case are real drawbacks, but they are not dealbreakers.

Who should buy at full price: Frequent flyers, office workers in noisy environments, and anyone who prioritizes ANC above all else.

Who should wait for a sale: Casual listeners who primarily use headphones at home, where ANC matters less.

Rating after six months: 9.0/10 (down from 9.3 in our initial review, due to comfort and case concerns).
