Sony XM4C vs. XM5 vs. XM6: Which headphones should you buy?

Sony WH-1000XM4C vs. WH-1000XM5 vs. WH-1000XM6

Design and build

• WH-1000XM5 (2022): Often discounted, but lacks moisture protection, uses older Bluetooth, folds flat rather than inward, and has ear pads that are difficult to remove. The presenter also warns of a possible hinge-breaking risk and shallow earcups.
• WH-1000XM6 (2025): Costs $450. It folds inward and has an updated hinge and newer Bluetooth features, though some users may be concerned about its plastic construction.
• WH-1000XM4C: A refreshed version of the older XM4 design, with updated materials, internal construction, and wireless hardware. The presenter favors its established design, padding, and expected durability. It weighs about the same as the XM6.

All three models have physical buttons and a touchpad on the right earcup. Some people report trouble using the controls in severe cold, though the presenter used the XM4 and XM5 at −20°C without issues.

All three support SBC, AAC, and LDAC wireless codecs, as well as analog wired listening. None supports USB-C audio. LDAC can provide higher-bitrate audio but may reduce connection stability.

The XM4C and XM6 batteries can technically be replaced, but doing so requires opening the headphones and removing several screws. The video does not describe the XM5 battery as user-replaceable.

Design preference: The presenter picks the XM4C for refining a proven design and offering good padding, rather than claiming it is objectively superior.

Features and app

Each model supports firmware updates and offers many settings through Sony’s somewhat outdated Sound Connect app. All three support 360 Reality Audio, transparency modes, and a multi-band equalizer.

• XM6: Has the broadest feature set, including sound-virtualization modes and LE Audio features. It is the only model that supports Auracast.
• XM5: Lacks LE Audio and has a less flexible equalizer than the XM6 and XM4C.
• XM4C: Supports Bluetooth 6 and may receive LE Audio features in a future update, but this is not guaranteed in the subtitles.

The XM5 uses Bluetooth 5.2, while the XM6 uses Bluetooth 5.3.

Feature winner: XM6.

Sound quality

All three have boosted bass and some emphasis in the high frequencies. This style of bass emphasis can make low notes less clear or obscure detail.

• XM6: Sounds somewhat more natural than the XM5, with a smoother bass transition and stronger upper mids and highs. Its notable drawback is a peak around 10 kHz that the app’s equalizer cannot remove.
• XM4C: Also has smooth bass, but a dip in the 1–4 kHz range can make some sounds seem unusually dull or unfamiliar.

Head-Fi multidimensional sound-quality ratings favor the XM6. The presenter says the other two are still decent, and that differences partly come down to personal taste.

Sound preference: XM6, though none of the models is presented as universally bad.

Active noise cancellation

All three provide effective noise cancellation. The XM4C and XM6 outperform the XM5 by about 4–8 dB between 200 and 500 Hz, helping reduce speech, traffic, and similar everyday noise.

The presenter finds the XM4C easier to fit correctly than the XM6 and therefore personally prefers its ANC experience. Overall, the differences are described as modest.

ANC result: XM4C and XM6 tie; the presenter leans toward the XM4C for fit.

Microphone quality

The video reports reader survey results based on controlled microphone samples from four announcers across five noise environments. The XM5 receives mostly favorable ratings, while the newer XM6 and XM4C are rated average—even though the presenter says they sound similar.

Because the survey criteria may have shifted over time, the presenter recommends listening to the samples rather than treating the results as definitive. No specific model scores are given.

Battery life

In standardized testing, volume was matched and music played until the batteries ran out:

Model Tested battery life XM4C 28 hours, 26 minutes XM5 31 hours, 53 minutes XM6 37 hours, 14 minutes

The presenter says the XM6 could last about a week with typical use, while the XM4C may need charging during a long commute. The XM6 has the best tested battery life.

Overall recommendation

• Choose the XM6 for the newest features, strongest overall sound tuning, and longest battery life—if its high price is acceptable.
• Choose the XM4C for a comfortable, more classic design and strong ANC without major compromises, particularly on a tighter budget.
• Choose the XM5 only at a very steep discount. The presenter considers it a good product in its time, but says its older features and concerns about the hinges and shallow earcups make it harder to recommend now.

Presenter’s overall perspective

The presenter sees the performance gap as fairly small and says price will decide it for many buyers. Their preferences are the XM4C for design and fit, and the XM6 for features, sound, and battery life.
