Sony WF-1000XM6 Review

Sony's flagship earbuds have always played the same game: pack in every conceivable feature, lead the market on ANC, and charge a premium for it. The WF-1000XM6 continues that tradition — but this generation arrives in a more competitive landscape than ever, and whether it's worth your money depends heavily on what you actually need from a pair of earbuds.

ANC: Still Class-Leading, With a Catch

Let's start with the headline: noise cancellation. RTINGS gave the XM6 a 9.6 for noise isolation — outstanding by any measure — and notes it's a meaningful step up from the XM5, especially in low-frequency attenuation. That means better performance against engine rumble, HVAC hum, and commute noise. A direct user comparison against the Technics EAH-AZ100 scored Sony's ANC at 9/10 versus Technics' 8.5/10.

But here's the catch that keeps showing up across reviews: to unlock that full market-leading silence, you need to use Sony's proprietary foam tips. Multiple users found the foam tips uncomfortable for extended wear, and some noted that third-party foam tips like Foamax or Comply close most of that gap while being far more comfortable. If you plan to swap tips — and many people do — factor that into your expectations.

Sound Quality: A Real Upgrade Over the XM5

This might be where the XM6 earns its biggest praise. Long-time WF-1000X users note that the XM6 essentially combines the best of both worlds: the bass warmth and fun factor of the XM4 with the clarity and accuracy of the XM5. The sub-bass specifically has received a noticeable boost, giving the earbuds a physicality that makes them sound more like larger headphones. RTINGS confirms the frequency response stays close to a warm sound profile with a healthy bass boost, flat mids, and a well-aligned treble — and driver matching is extremely tight, meaning the left and right cups perform consistently.

Interestingly, at least one audiophile-leaning reviewer on r/headphones noted that the XM6 is "tuned better than many wired IEMs" — a comment that would have been eyebrow-raising a few years ago but speaks to how far Sony has come on sound tuning.

The new 10-band EQ and sound presets in the app add flexibility, though the "Find My EQ" personalization feature reportedly underdelivered for some users — likely a firmware issue more than a fundamental flaw.

Fit: Better Than the XM5, Still Polarizing

Sony changed the shape again — they always do — and reactions are mixed. The XM6 is more bulbous than its predecessor and sits differently in the ear, using the front of the ear lobe for a more secure anchor. For users who constantly had to readjust the XM5, this is a genuine improvement. But for others, the new shape is simply too large and "ugly," sticking out of the ear more noticeably.

One Reddit commenter summed up a frustration shared by several: "They made big steps with the XM4 and XM5 in terms of fit. It's like they saw the most uncomfortable, unstable earbuds from Samsung and decided to use that as their base design." That's harsh, but the fit debate is real. If possible, try them in-store before buying.

Microphone and Call Quality: Improved, But Not the Best

Call quality on Sony earbuds has been a long-running sore point, and the XM6 makes genuine progress here. RTINGS scores the mic at 6.9 — "okay" — noting better detail and clarity than the XM5 and improved voice/background separation. However, loud environments can trigger the noise gate in a way that briefly cuts out your voice.

In a head-to-head against the Technics AZ100, Sony edges ahead in quiet rooms but loses ground in noisy environments, where Technics' Voice AI does a better job of isolating speech. For regular calls in an office or at home, the XM6 is fine. For frequent outdoor calls or working from noisy environments, it's not the standout option. Reddit users have been blunt: "The call quality on the Sonys has been terrible forever" — and while it's improved, it's still not a strong suit.

Features and App: More Polish, One Standout Addition

Touch controls are more reliable this generation — smaller, better-shaped touch surface means fewer accidental taps, a genuine improvement over the XM5. Custom control mapping is now supported, which was a long-requested feature. Multipoint connection and Adaptive Sound Control both return, with the latter reportedly better at detecting context.

The new Battery Care mode — limiting charge to 80% to protect long-term battery health — is a quiet but important addition. Battery degradation was a real complaint with the XM4 and XM5. One longtime user noted being "traumatised" by premature battery failure in previous generations. The fact that Sony addressed this directly is meaningful, even if it's not a flashy selling point.

The new Background Music mode (simulating room, living room, or cafe acoustics) sounds gimmicky on paper but reportedly works surprisingly well when you want ambient listening rather than immersive playback.

The Durability Question

This is where the community is understandably cautious. Multiple Reddit users flagged battery longevity as a known weakness in past Sony earbuds, with one commenter saying: "I'll hold out and see if they still work after a year of use. Batteries were the weakness on the previous version and I won't be fooled again." The Battery Care feature is a direct response to this, but it's still too early to say whether the XM6 has genuinely solved the problem. If you're buying for the long haul, keep an eye on long-term user reports over the next 6-12 months.

How It Stacks Up Against the Competition

The XM6's most direct rival right now is the Technics EAH-AZ100. Based on a detailed head-to-head comparison, Sony wins on ANC and transparency mode quality (better noise floor handling), while Technics wins on soundstage, call quality in noisy environments, and touch control customization. For pure music listening in loud environments — commutes, flights, open offices — Sony is the pick. For calls and audiophile-leaning sound preferences, Technics gives it a real fight.

AirPods Pro and Galaxy Buds remain the benchmark for natural transparency mode feel, and both those options offer tighter ecosystem integration for Apple and Samsung users respectively. The XM6's transparency mode is good, but reviewers consistently note it still falls short of AirPods' natural feel.

Who Should Buy the WF-1000XM6?

• Buy it if ANC performance is your top priority and you spend a lot of time commuting, flying, or in loud open offices. It's the best passive+active noise isolation combo available in true wireless right now.
• Buy it if you're coming from the XM4 or earlier — the sound and feature upgrades are substantial.
• Skip it if call quality is critical to your workflow. Technics AZ100 is the better choice there.
• Skip it if you're on XM5 and satisfied — the upgrade is real but incremental. Better sound, better fit for some, better ANC, but nothing that demands an immediate switch.
• Wait if you've had battery issues with previous Sony earbuds. Give it 6 months of real-world durability data first.

Frequently Asked Questions

Q: Is the Sony WF-1000XM6 worth upgrading from the XM5?

A: For most XM5 users, the upgrade is real but not urgent. The XM6 offers better ANC (especially in low frequencies), improved bass response, more reliable touch controls, and the new Battery Care feature. If you're satisfied with your XM5s and the battery is still healthy, there's no pressing reason to switch immediately.

Q: How does the WF-1000XM6 ANC compare to AirPods Pro?

A: The XM6 leads on raw ANC performance, especially for low-frequency noise like engines and HVAC. However, AirPods Pro offers a more natural-feeling transparency mode that multiple reviewers still consider the benchmark. For pure noise blocking, Sony wins; for natural-sounding transparency, AirPods remain ahead.

Q: Are the WF-1000XM6 good for phone calls?

A: They're improved over the XM5 — RTINGS scores the mic at 6.9 — but call quality has historically been a weakness for Sony earbuds, and the XM6 doesn't fully fix that reputation. In quiet rooms they sound natural; in noisy environments, rivals like the Technics AZ100 outperform them on voice isolation.

Q: Do the foam tips make a big difference for ANC?

A: Yes, significantly. Reviewers note that the best ANC performance requires Sony's included memory foam tips. Third-party foam alternatives like Comply or Foamax close most of the gap while offering better comfort, but if you use standard silicone tips, you'll sacrifice a noticeable amount of ANC performance.

Q: Has Sony fixed the battery degradation issues from previous generations?

A: Sony introduced a Battery Care mode that limits charging to 80% to protect long-term battery health — a direct response to complaints about the XM4 and XM5. Whether this fully solves the problem is still unknown; the earbuds are too new for long-term data. It's an encouraging step, but cautious buyers should wait for 6-12 month user reports.
