Sony WF-1000XM6 Review: The Reigning Champion Faces Real Challengers [2025]

Sony's 1000X earbuds have owned the "best wireless earbuds" conversation for years. Each generation brought incremental improvements, and year after year, they stayed at the top of the heap. The WF-1000XM6 continues that tradition with excellent sound quality, a mountain of features, and solid active noise cancellation. But here's what's different this time around: the competition isn't chasing anymore. They've caught up. Some have even passed.

I spent three weeks testing the M6 earbuds, and I'll be honest, they're still fantastic. The audio quality remains one of the best you'll get from wireless earbuds. The feature set is absurd—if you use Sony's app ecosystem, you'll find almost everything you could want. The touch controls work reliably, something I can't say about most earbuds. Battery life is solid. And sure, the active noise cancellation still works. But ANC performance? That's where things get interesting. Sony's performance here lags behind newer flagships, and that's a legitimate problem for a $299 earbud.

The bigger issue, though, isn't any single flaw. It's that Sony's dominance was built on doing everything well. Now that other manufacturers have caught up on features, sound quality, and noise cancellation, you're paying a premium for Sony's brand name and its superior sound tuning. That might be worth it to you. But it's no longer the automatic choice it once was.

TL; DR

• Sound quality remains excellent: Deep bass, clear highs, and warm midrange make music enjoyable across genres, though some prefer other tuning profiles
• ANC performance disappoints: Active noise cancellation lags behind competitors like Apple Air Pods Pro 2 and Google Pixel Buds Pro, particularly on lower frequencies
• Feature-packed but familiar: Sony's long list of capabilities includes Speak-to-Chat, Adaptive Sound Control, and spatial audio, but most are holdovers from previous models
• Fit issues are real: The foam ear tips lack stability, and the rounded design doesn't secure deeply enough for many users, impacting both comfort and sound quality
• Pricing pressure: At $299, the M6 costs more than equally capable competitors while offering weaker ANC, making the value proposition questionable
• Bottom line: Still a strong option for Sony ecosystem users who prioritize sound quality and features over noise cancellation, but no longer the obvious top choice

Sony M6 excels in sound quality but lags in ANC performance compared to Apple and Google. Estimated data based on product reviews.

The Design: Smaller Isn't Always Better

For the third generation in a row, Sony completely redesigned the WF-1000XM6. This time, the company ditched the bulkier shape of the M4 and M5 models for a rounder, pill-shaped design that's noticeably smaller. On paper, this is a win. Compact earbuds are easier to wear all day, they look less obvious, and they fit in smaller pockets. I appreciated the size reduction immediately.

The problem? The pill shape trades stability for compactness. The rounder edges don't sit as securely in your ear, especially when you're moving around. During my first week testing, I kept getting slight movement during workouts. I tried switching to the silicone M3 tips from previous generations, which helped, but that defeats the purpose of Sony shipping new foam tips with the M6.

The foam tips are Sony's biggest miss here. The company introduced them on the WF-1000XM4, and they've remained problematic. They're soft, which is comfortable initially, but they compress over time and lose their seal. During my three weeks of testing, the fit test in Sony's Sound Connect app consistently confirmed an air-tight seal in my right ear only. Never both. This inconsistency directly impacts sound quality and ANC effectiveness.

The exterior panel remains touch-sensitive, accepting various taps for playback, noise modes, and volume control. Here's where Sony actually nailed something: the touch controls work reliably without requiring exact timing or repeated taps. I can reliably adjust volume by tapping the right earbud to increase or left to decrease, which sounds simple until you compare it to other earbuds where you're constantly repeating gestures because they didn't register.

The M6 also includes basic conveniences that feel standard at this price point: multipoint Bluetooth for switching between devices, wireless charging for the case, and IPX4 water resistance. Wear detection returns, automatically pausing audio when you remove an earbud. These aren't differentiators anymore; they're table stakes. But they're solid implementations that work consistently.

Sound Quality: Where Sony Still Dominates

Sound quality is where the WF-1000XM6 truly shine. Sony engineered new drivers with soft edges for deeper bass and a lightweight, rigid dome for clearer treble. There are also micro-notches around the edges designed for what Sony calls "clearer and smoother" overall sound. Whether or not those notches make a measurable difference is debatable, but the end result is undeniably pleasant.

With the stock EQ and DSEE Extreme upscaling enabled, the M6 earbuds deliver warm, full sound. The bass is thick without overpowering the mix. Highs cut through cleanly. The midrange is ample, preventing finer details from getting lost. Listen to atmospheric tracks like Erika de Casier's "Lifetime," and you'll hear vocals floating over the bassline and drums while percussive piano chops through and synth details pop throughout. When strings arrive, they don't muddy the mix; they sit naturally in the soundstage.

This tuning is particularly effective for streaming music, which is what most people do. It masks the compression artifacts in Spotify and Apple Music streams. Pop, hip-hop, R&B, and electronic music all sound great. Jazz benefits too, with good instrument separation and detail retrieval. The 360 Reality Audio and Spatial Sound Optimization features add dimensionality for compatible content, though they're optional.

That said, Sony's tuning isn't for everyone. Some listeners prefer a more neutral, reference-like sound signature. The WF-1000XM6 lean toward the warm, fun side of the spectrum. If you want to hear exactly what the recording engineer intended, other options might suit you better. But if you want earbuds that make music enjoyable, Sony nailed this.

The EQ presets allow you to adjust the sound profile, and you can create custom EQ curves in the Sound Connect app. I experimented with various profiles, but I kept returning to the stock settings with DSEE Extreme active. That combination just works.

Active Noise Cancellation: The Weak Link

Here's the thing that surprised me most about the WF-1000XM6: the active noise cancellation isn't as impressive as it should be at this price point. Sony still includes ANC, and it still works, but it lags behind competitors in 2025.

The ANC performance is most noticeable on lower frequencies. White noise, HVAC hum, and traffic rumble don't get suppressed as effectively as on competing flagship models. On my commute, I could hear the baseline rumble of train noise even with ANC enabled. The M6 reduces it, but not as much as I'd expect from a $299 earbud. Medium and higher frequencies get better suppression, but the overall effect is less comprehensive than newer competitors offer.

This matters because ANC is a primary reason many people buy premium wireless earbuds. If you're spending three hundred dollars, you expect world-class noise cancellation, not "pretty good." Sony's advantage in this category has evaporated. Apple Air Pods Pro 2 and Google Pixel Buds Pro both deliver superior ANC performance, particularly on low-frequency noise.

The ANC limitation likely ties back to the fit issues I mentioned earlier. A secure, deep-inserted earbud creates a better acoustic seal, which is essential for effective noise cancellation. If the M6 isn't sitting deep enough in your ear, the ANC can't work as effectively. This creates a vicious cycle: the design is less stable, the fit is less secure, and the noise cancellation suffers as a result.

Sony included Ambient Sound and Ambient Transparency modes, which let background noise in when needed. These work well for quick conversations or staying aware of your surroundings. The transition between modes is smooth, and you can customize what you hear. But again, these are table-stakes features now, not differentiators.

Features: The Mountain of Capabilities

Sony has loaded the WF-1000XM6 with features. Nearly all are holdovers from previous generations, but that doesn't make them any less useful.

Adaptive Sound Control automatically adjusts ANC settings based on your activity or location. It uses GPS and motion sensors to detect whether you're walking, running, in a vehicle, or sitting still, then adjusts noise cancellation accordingly. In practice, it works smoothly, though you can disable it if you prefer manual control.

Speak-to-Chat pauses audio and activates ambient sound when you start talking. This is genuinely useful for quick conversations without removing your earbuds. The downside? It's easily duped by coughs or clearing your throat, causing unwanted interruptions. After three weeks, I still found it triggering unexpectedly.

Quick Access shortcuts let you reach Amazon Music, Apple Music, Endel, Spotify, or YouTube Music with two or three taps, depending on configuration. If you primarily use one music service, this can save time, but it's a minor convenience.

You can accept and reject calls using head gestures, and during calls, you can pipe in your own voice, which helps call quality when background noise is present. Voice Assistant integration lets you say "Assistant" to activate controls for playing, pausing, skipping, or replaying songs, plus volume adjustment. That's the extent of voice control's abilities, though, which feels limited compared to some competitors.

Power management features include Auto Power Save mode, which disables custom EQ, DSEE Extreme, Speak-to-Chat, and voice control when the M6 hits 20 percent battery remaining. A Battery Care tool extends battery lifespan by preventing full charges. Automatic Power Off turns the earbuds off after extended periods outside the case.

The Sound Connect app puts battery levels front and center and lets you customize what appears on the home screen. You can create custom EQ profiles, adjust spatial audio settings, and access all the features mentioned above. The app is well-designed and responsive, though it's feature-heavy enough that you might need time to explore everything available.

Battery Life: Respectable, Not Revolutionary

Sony rates the WF-1000XM6 at eight hours of playback per charge, or twelve hours with ANC disabled. In real-world testing, I achieved approximately seven and a half hours with moderate ANC and typical volume levels. That's respectable but not class-leading.

The charging case holds multiple additional charges, extending total listening time to around twenty-four hours. That's enough for typical usage, but if you're traveling and can't charge frequently, competitors offer better total capacity.

Wireless charging on the case is convenient, and the magnetic attachment is strong enough that the earbuds won't fall out during normal handling. Fast charging isn't available, so you're waiting the normal twenty minutes or so for a full case charge.

Sony WF-1000XM6 offers strong sound quality and features but lags in ANC and fit stability compared to competitors. Estimated data based on market trends.

Comfort and Wearability: Inconsistent Across Users

Your experience with the WF-1000XM6 will depend heavily on your ear shape and size. For me, the fit felt slightly unstable, particularly during movement. After three weeks of testing, I never fully adapted to them. The rounded design sits more in the ear canal opening rather than deeper inside, which is comfortable initially but feels loose during workouts.

For others with different ear anatomy, the pill shape might fit perfectly. The only way to know is to test them yourself. If they fit well, you'll love the comfort for all-day wearing. If they don't, no amount of EQ tweaking fixes the core issue.

The touch controls don't add pressure that would displace the earbuds, which is smart engineering. But the slight movement I experienced during running wasn't ideal. I never lost them, but I noticed it.

Comparing the M6 to Previous Generations

The WF-1000XM5 offered better fit stability with its more angular design. The M6's rounder shape is smaller but less secure. Sound quality is marginally improved on the M6, though the difference is subtle. ANC performance? It's actually worse than the M5, which is concerning given the two-year gap between releases. The M5 remains a solid alternative if you can find them discounted, and you might actually prefer their fit.

The M4 is even older, but it had better ANC performance than the M6, believe it or not. If noise cancellation is your priority, it's worth checking what previous generations are still available at lower prices.

Connectivity and Pairing: Seamless Integration

Multipoint Bluetooth connectivity works smoothly, letting you connect to two devices simultaneously and seamlessly switch between them. When your phone rings while you're listening to music on your laptop, the M6 automatically switches to handle the call. This works reliably and saves the friction of manual disconnection and reconnection.

Initial pairing is straightforward. The earbuds appear in your Bluetooth settings after removing them from the case. Once paired with your primary device, they remember the connection and reconnect automatically when powered on.

Codec support includes LDAC, AAC, SBC, and the proprietary DSEE technology. If your device supports it, LDAC provides higher-quality streaming over Bluetooth, though the benefit over standard AAC is subtle unless you have trained ears.

Estimated data suggests that reducing the price and improving ANC performance could have the highest impact on consumer satisfaction for the Sony M7 earbuds.

Comparing to Current Competitors

The earbuds market has evolved significantly. Apple Air Pods Pro 2 offer superior ANC and seamless integration with Apple devices, though their sound signature is less warm than the M6. Google Pixel Buds Pro deliver competitive ANC and feature deep integration with Android, plus they're cheaper. Bose Quiet Comfort Earbuds 2 focus on ANC and deliver excellent performance in that area. Even Nothing Ear offer competitive feature sets and better ANC than the M6 at lower prices.

Sony's advantage—sound quality and feature completeness—is still meaningful, but it's not enough to justify the $299 premium when competitors match them on ANC and undercut them on price. The value proposition has shifted.

Microphone Quality and Call Performance

The microphone quality during calls is clear and crisp. Background noise reduction works decently, and the other party reported they heard me clearly even in moderately noisy environments. The piping in of your own voice during calls helps you hear yourself, improving confidence during conversations.

Compared to dedicated headsets, the M6 won't dominate, but they're perfectly serviceable for occasional calls. If you're taking calls daily, they're adequate without being exceptional.

Durability and Build Quality

The M6 earbuds feel well-constructed. The plastic is durable, and the touch panels seem robust. IPX4 water resistance means they'll survive sweat and light rain, though you shouldn't submerge them. The charging case is magnetic and feels premium. After three weeks of heavy testing, including workouts and commuting, they showed no signs of degradation.

Longevity depends on battery health. The battery care feature helps extend lifespan, but all lithium batteries degrade over time. After two years of daily use, you should expect capacity to drop to around 80 percent. That's typical for wireless earbuds.

Should You Buy the Sony WF-1000XM6?

The WF-1000XM6 remains excellent wireless earbuds, but they're no longer the obvious choice. Here's who should buy them:

Buy the M6 if you prioritize sound quality and want a warm, pleasant tuning profile that makes music enjoyable across genres. Buy them if you're deeply integrated into Sony's ecosystem and value the seamless feature integration. Buy them if Adaptive Sound Control and Speak-to-Chat features genuinely enhance your daily routine. Buy them if the fit works well with your ear shape and you're willing to spend $299 for comfort.

Skip the M6 if noise cancellation is your primary use case. Other options genuinely outperform them here, and that's a major weakness for a $300 earbud. Skip them if you need the best fit stability. Skip them if you're on a budget—competitors offer 85 percent of the experience for 60 percent of the price.

Sony hasn't included any major price drops or bundle offers at launch, so you'll pay full freight. Previous generations sometimes drop in price once new models launch, so patience might reward you with

Future Outlook and What's Missing

For the M7 (inevitable in 2026 or 2027), Sony needs to address ANC performance directly. The company shouldn't accept being behind competitors in this area. Better fit options—perhaps multiple earbud size variants or custom-molding—would help. Improved battery capacity would extend listening time, matching competitors. And honestly, Sony could afford to reduce the price. At

What's also missing is meaningful innovation. The M6 feels like an incremental update, not a generational leap. The design is smaller, but at the cost of fit stability. The sound is marginally better, but you need trained ears to hear it. The features are the same ones people have been using for two generations. For customers who upgraded from the M4 or M5, the M6 doesn't offer enough improvement to justify the cost.

The Bottom Line

The Sony WF-1000XM6 remain exceptional wireless earbuds. The sound quality is genuinely excellent, the feature set is comprehensive, and the touch controls work reliably. If the fit works for your ears, you'll enjoy wearing them. If you're a Sony ecosystem user who values those features, you'll appreciate the integration.

But Sony's dominance era has ended. The competition caught up. Other earbuds match or exceed the M6 on ANC. Other earbuds offer better fit stability. Other earbuds cost significantly less. Sony still offers the best overall sound tuning, but that's one dimension among many.

If you loved previous Sony models and they fit you well, the M6 are worth considering. But if you're choosing your first premium earbuds, test multiple options. The obvious choice is no longer so obvious.

FAQ

What makes the Sony WF-1000XM6 different from previous models?

The M6 features a redesigned, more compact pill-shaped housing that's smaller than previous generations. Sony engineered new drivers with soft edges for deeper bass and a lightweight dome for clearer treble. The touch controls work more reliably, and battery efficiency improved slightly. However, the design trade-off—smaller size for reduced fit stability—is a notable change from the M5.

How does the ANC performance compare to competitors?

The WF-1000XM6 deliver adequate active noise cancellation on mid and high frequencies, but low-frequency performance lags behind current competitors like Apple Air Pods Pro 2 and Google Pixel Buds Pro. The ANC weakness is the most significant area where the M6 underperforms compared to earbuds in the same price range, particularly for users who commute or work in loud environments.

Is the fit issue a dealbreaker?

The fit depends entirely on your ear shape. The rounded pill design works well for some users but feels slightly unstable for others. Sony's foam ear tips are the primary concern, as they lack the stability of the company's previous silicone options. Many testers recommend switching to third-party silicone tips to improve fit security and ANC effectiveness. Test them before committing to the purchase.

What features does the Sound Connect app offer?

The Sound Connect app provides access to Adaptive Sound Control, Speak-to-Chat, custom EQ creation, spatial audio settings, Ambient Sound adjustments, and voice assistant configuration. The app displays real-time battery levels for both earbuds and the case and lets you customize what features appear on the home screen. The app is responsive and well-designed, though it's feature-dense enough to require some exploration.

How long does the battery last in real-world use?

Sony rates the WF-1000XM6 at eight hours per charge with ANC enabled, or twelve hours with ANC disabled. Real-world testing achieved approximately seven and a half hours with moderate ANC and typical volume levels. The charging case provides multiple additional charges, extending total listening time to around twenty-four hours. Wireless charging is included, though fast charging is not available.

Should I buy the M6 or wait for a better deal on the M5?

The WF-1000XM5 often becomes discounted once the M6 launches, potentially dropping

Can the M6 work with both Android and iOS devices?

Yes, the WF-1000XM6 support multipoint Bluetooth connectivity, allowing them to connect to two devices simultaneously regardless of platform. They work with any device supporting standard Bluetooth audio streaming. However, some Sony-specific features like LDAC codec support work better on Android, while deeper integration features are available on iOS if you use Apple Music or Apple's ecosystem.

Is the $299 price tag justified?

The price is justified only if you prioritize excellent sound quality and feature completeness over noise cancellation performance and cost efficiency. At $299, you're paying for Sony's superior tuning and feature set, not for ANC performance where competitors match or exceed them. If ANC is your priority, competitors offer equal or better performance at lower prices. If sound quality is paramount and the fit works for your ears, the M6 value is reasonable.

Final Thoughts and Recommendations

After three weeks with the Sony WF-1000XM6, I'm impressed by what Sony has built while simultaneously disappointed by what's missing. The earbuds are genuinely good. The sound is warm and engaging. The features are plentiful. The build quality is solid.

But good isn't good enough at $299 anymore. The wireless earbuds market matured significantly in the past two years. What was once Sony's exclusive advantage—a comprehensive feature set, excellent sound quality, and functional ANC—is now table stakes. Multiple competitors offer similar comprehensive experiences for less money.

Sony's decision to prioritize compact design over fit stability was a misstep. The M5 offered a better balance. The decision to accept weaker ANC performance was another misstep. For a company charging three hundred dollars, ANC leadership should be non-negotiable.

That said, if the M6 fit your ears well, if you love warm sound signatures, if you're deep in the Sony ecosystem, they're worth considering. They're still excellent earbuds. They're just no longer the obvious choice, and that's a significant shift from the last five years of Sony dominance.

Test them yourself. Try different ear tip sizes. Use them in your actual commuting or working environment. Only then make a decision. The wireless earbuds market is competitive enough now that personal fit and preference matter more than brand pedigree. Sony's 1000X legacy is strong, but it's not enough to justify automatic loyalty anymore.
