Sony WF-1000XM6: Can They Reclaim the ANC Crown?
Sony’s latest flagship wireless earbuds, the WF-1000XM6, arrive with a significant mandate: to not only match but surpass the impressive feats of their predecessors. The WF-1000XM5 were, and arguably still are, a benchmark for noise cancellation and audio fidelity in the true wireless earbud market. However, the competitive landscape has intensified. Rivals like Bose, with their QuietComfort Ultra 2 earbuds, have pushed the boundaries of silence, while others have prioritised comfort and fit. The burning question is: can the WF-1000XM6 not only keep pace but decisively win back the top spot?
Boasting a slimmer profile, a new QN3e processor engineered for enhanced noise cancellation and superior sound, and a host of refinements, these earbuds present a compelling case for being Sony’s finest wireless offering to date. Having spent over a month with the WF-1000XM6, I’ve subjected them to the rigours of daily life – from the cacophony of busy train platforms and the focused environment of working from home to long listening sessions with podcasts, music, and audiobooks. Priced identically to their predecessors, the expectations are understandably sky-high.
Rigorous Testing: A Deep Dive into Performance
My evaluation of the Sony WF-1000XM6 has been comprehensive, spanning over a month of continuous use as my primary audio companions. This involved navigating the urban jungle on public transport, finding focus while working remotely, enduring long walks, and even accompanying me to the gym. The true test of their adaptive noise cancellation capabilities came in environments brimming with distractions, such as packed train carriages, bustling cafes, and noisy, traffic-laden streets.
Beyond their noise-cancelling prowess, I’ve put their communication abilities to the test. Numerous calls were made in both serene indoor settings and exposed, windy outdoor locations to gauge the effectiveness of the improved microphone array and AI voice isolation. For audio fidelity, I delved into a diverse range of music genres, podcasts, and audiobooks across popular streaming platforms like Spotify, Apple Music, and Tidal. The newly introduced 10-band EQ within the Sony Sound Connect app was thoroughly explored, alongside other customisation options.
Crucially, comfort and the security of the fit were assessed, particularly during periods of movement and physical activity. After a month of immersion, here’s my detailed breakdown of Sony’s latest wireless earbud endeavour.

Design and Comfort: A Refined Fit
The transition from the WF-1000XM4 to the WF-1000XM5 marked a dramatic overhaul in design, resulting in both the earbuds and their charging case becoming considerably more compact. The WF-1000XM6, however, seems to have taken a step back towards a more substantial feel, though this is not necessarily a drawback.
While the XM5s were approximately 25% smaller than their predecessors, their rounded design sometimes resulted in them feeling more like they rested on the ear rather than snugly within it, leading to occasional discomfort during extended wear. At first glance, the XM6s appear larger than the XM5s. While their surface area might be slightly greater, Sony states they are actually 11% slimmer. This reduction in profile makes a surprising, positive difference.
Their shape has shifted from a near-perfect sphere to a more elongated, bean-like form. This subtle change, coupled with the slimmer profile, allows them to nestle more comfortably within the ear canal. The contoured design follows the natural curves of the inner ear more closely, creating a tighter seal without the pressure points that sometimes afflicted the XM5s. It’s a curious paradox that a more elongated shape translates to a more comfortable and secure fit, but it undeniably works.
Sony has retained the use of polyurethane foam ear tips, which, when properly fitted, create an exceptional seal, allowing you to virtually forget you’re wearing them. I’ve managed hours of listening without experiencing the uncomfortable pressure often associated with long-term earbud use. The new ventilation system engineered into the buds also effectively mitigates that slightly blocked or occluded sensation that can occur during chewing or walking. Three sizes of ear tips (small, large, and extra-large) are included in the box to ensure a personalised fit.
The improved fit also translates to enhanced stability. A minor annoyance with the XM5s was their tendency to shift during brisk walks or minor adjustments. The XM6s, in contrast, feel remarkably planted. I’ve experienced minimal need for readjustment; they simply stay put.
For those prone to fumbling, the XM6s also address the slippery surfaces of the XM5s. The glossy finish has been replaced with a more matte texture, providing a much-improved grip when removing the earbuds from your ears or the charging case.
Similar to the XM5s, a tactile dot on the left earbud aids in distinguishing between left and right buds, a thoughtful touch for users with visual impairments. Touch controls are present on the outer surface of each bud and are responsive, with a generous tap area. Customisation of these controls is available through the Sony Sound Connect app. While the touch-based volume control, requiring repeated taps, can feel a tad finicky, and I personally prefer a capacitive slider, it’s a minor quibble in an otherwise well-executed interface.
The charging case, however, represents a departure from the XM5’s sleek, compact design. The XM6 case is noticeably bulkier and heavier, with sharper edges and a more utilitarian aesthetic. While still pocketable, it lacks the modern, pebble-like charm of its predecessor. The magnetic hinge, while secure enough to prevent accidental openings (a common issue with some competitors like AirPods Pro), doesn’t feel quite as robust as the XM5’s.
The WF-1000XM6 are available in the same colour options as the XM5: black and platinum silver. The black variant I tested boasts a minimalist and sophisticated appearance.
Feature Set: Familiar Strengths with New Innovations
The core feature set of the WF-1000XM6 will feel familiar to users of the XM5, but Sony has introduced some notable enhancements. Multipoint connectivity for simultaneous pairing with two devices remains, as does LDAC support for high-resolution audio on compatible Android devices, and DSEE Extreme for upscaling compressed audio streams. Features like Speak-to-Chat (which thankfully remains off by default) and Quick Attention Mode (activating ambient sound by cupping your ear) are also present. The Sony Sound Connect app, while packed with customisation options, can initially feel a little overwhelming due to the sheer number of toggles and sliders.
One of the most significant upgrades is the expanded 10-band equaliser. While the XM5’s five-band EQ was adequate, the granular control offered by the 10-band EQ allows for far more precise sound tuning. Sony has also included a broader array of presets to get you started. For those who prefer a less hands-on approach, the “Find Your Equaliser” feature is a standout. It presents short audio samples, allowing you to select your preference and tailor the sound profile accordingly.
A new dedicated gaming preset aims to enhance directional audio cues, such as footsteps, which will be a boon for mobile gamers. Mirroring the WH-1000XM6 headphones, the “Background Music Mode” is also included. This feature subtly pushes the audio away from your immediate perception, creating an effect akin to soft background music in a cafe, giving the impression that the sound is emanating from outside your head. While somewhat gimmicky, it’s a feature I still find enjoyable.
Sony has also increased the antenna size by approximately 1.5 times compared to the XM5, leading to a demonstrably more stable connection. I experienced no dropouts, even when navigating the notoriously signal-challenging London Underground or in busy shopping centres.
Future-proofing is also a key consideration, with the WF-1000XM6 supporting Bluetooth LE Audio. This newer, more energy-efficient version of Bluetooth is designed to enhance stability and reduce power consumption, ultimately leading to better audio quality at lower bitrates.
However, a few features found in some competing earbuds are absent. Notably, the latest AirPods Pro 3 include an integrated heart rate sensor for workout tracking. While this is a minor omission, it’s perhaps the only significant feature missing from the XM6’s otherwise extensive offering, which still far surpasses that of the AirPods Pro.
Noise Cancellation and Call Quality: A Tale of Two Strengths
Sony has long been a titan in the active noise cancellation (ANC) arena, but recent years have seen rivals like Bose’s QuietComfort Ultra 2 deliver an almost unnerving level of silence. The WF-1000XM6, however, represents a substantial leap forward in Sony’s ANC capabilities.
The promotional material depicts a user tapping their XM6s in a noisy urban environment, with the sound miraculously melting away. My experience mirrored this almost precisely. Activating ANC on the XM6s creates a profound sense of quietude. High-frequency noises, such as sirens, chatter, and screeching train brakes, are significantly attenuated compared to the XM5s, a testament to Sony’s claimed improvements in mid-to-high frequency noise reduction.
Sony’s traditional strength in mitigating low-frequency sounds remains evident. The rumble of traffic and the hum of the Underground become virtually imperceptible. There’s a more pronounced “vacuum seal” sensation now, bringing them remarkably close to the Bose QuietComfort Ultra 2, though without the same aggressive pressure.
This enhanced ANC performance is largely attributable to significant internal upgrades. The new QN3e HD noise-cancelling processor, working in tandem with the V2 integrated processor, and an increased microphone count (eight instead of six – two internal and two external on each side) enable the earbuds to react more rapidly to ambient sound changes. Sony claims a 25% improvement in noise reduction over the XM5.
The Adaptive NC Optimizer has also been refined. It now continuously analyses your wearing conditions and external noise in real-time, adjusting ANC levels dynamically based on your surroundings and the seal of the ear tips. This feature worked flawlessly, seamlessly adjusting ANC strength without me even noticing as I moved between quieter and noisier environments.
While the ANC is undeniably impressive, Sony’s ambient sound mode is, quite frankly, exceptional. I’ve long considered Apple’s AirPods Pro the benchmark for transparency, but the WF-1000XM6 surpasses them. There is absolutely no discernible background hiss from the microphones, and it genuinely feels as though you’re not wearing earbuds at all. Voices sound natural and clear, allowing for full conversations without the artificial processing often associated with transparency modes. A particularly useful feature within the Sound Connect app allows you to minimise distracting external sounds while keeping voices clear – a perfect compromise between ambient mode and ANC.
However, I remain less enthusiastic about the default activation of Adaptive Sound Control. In everyday use, I tend to favour ambient mode over ANC. The automatic switching to ANC, even when simply relaxing at home with the TV on or walking down a quiet street, felt overly aggressive and intrusive. I quickly disabled this feature in favour of manual control over ANC and ambient modes.
Unfortunately, call quality remains the WF-1000XM6’s Achilles’ heel. Despite Sony’s claims of improved voice pickup through the new mic array, AI processing, and a bone conduction sensor, my experience suggests this is the weakest aspect of these earbuds. Friends and family consistently reported that I sounded muffled or as if I were speaking from within a confined space. My own recordings confirmed this, with my voice sounding indistinct, almost as if submerged.
The earbuds also exhibited peculiar behaviour with background noise. During tasks like washing dishes, the sound of running water was audible to the person on the other end while I was speaking, only to disappear when I stopped. The same occurred with background TV noise. It appears the system prioritises my voice by dynamically opening up the microphones, inadvertently allowing surrounding noise to intrude. This is a stark contrast to the crystal-clear call quality offered by rivals like the AirPods Pro 3. On a positive note, the wind reduction system is highly effective, allowing my voice to be heard even during strong gusts of wind, a valuable feature during the blustery British winter.
Sound Quality: A More Engaging Listening Experience
While the Sony WF-1000XM5 delivered clean and detailed sound, they sometimes lacked a certain “fun” factor, with bass that could feel somewhat restrained without EQ adjustments. Sony appears to have addressed this directly with the WF-1000XM6, and the improvement is immediately apparent.
The earbuds feature an updated 8.4mm dynamic driver, with Sony claiming refinements to its internal structure and integration with the new QN3e processor, which now handles 32-bit audio processing (up from 24-bit on the previous model). Furthermore, Sony has collaborated with Grammy-winning and nominated mastering engineers to fine-tune the sound signature. The result is a noticeable enhancement in instrumental separation, clarity, musicality, and, crucially, bass.
The improved bass is evident on pop tracks like Olivia Rodrigo’s “Bad Idea Right?”, where it maintains a tight and controlled presence. It’s even more pronounced on tracks like The Weeknd’s “The Hills,” where the sub-bass delivers a palpable rumble and the reverb is felt. The low-end swells beneath the mix without overpowering the vocals, offering a weightier and more impactful sound.
The mid-range is equally impressive. On jasmine.4.t’s “I Can’t Believe I Did This Without You,” vocals possess a delicate texture, feeling almost fragile at times. There’s a welcome warmth, and the guitars exhibit pleasing separation. The overall presentation feels more musical, particularly on the airier tracks from artists like Lowell.
Beyond music, the WF-1000XM6 excel with podcasts and audiobooks. Narrators and hosts come across with exceptional clarity and naturalness. Dialogue in films and TV shows is equally well-rendered. When paired with 360 Reality Audio on supported content, there’s a pleasing sense of width and height to the soundstage.
For those upgrading from the XM5, the WF-1000XM6 offer a tangible sense of refinement. The enhanced low-end provides a more engaging and lively listening experience, making them more enjoyable across all genres, with excellent instrumental separation. And for those who like to tinker, the updated 10-band EQ provides ample opportunity for personalised tuning.
Battery life remains consistent with the previous generation, offering up to eight hours from the earbuds alone with ANC engaged, and a total of 24 hours with the charging case. While this is a respectable figure, it’s not class-leading, with some competitors now offering up to 10 hours on a single charge. Nevertheless, it’s more than sufficient to see you through a full workday.
