Sony WH-1000XM6 Review: The flagship Active Noise Cancelling (ANC) headphone market is one of the most fiercely competitive battlegrounds in consumer electronics, dominated for years by a relentless back-and-forth between two titans: Sony and Bose.
Every two years, the industry holds its breath, waiting to see which brand will push the boundaries of silence, sound quality, and feature integration. Following the highly successful, though controversial, redesign of the WH-1000XM5, Sony’s engineers faced immense pressure to not just iterate, but to perfect the formula for the next generation. The result is the new Sony WH-1000XM6, a product that arrives not with a whisper, but with the definitive roar of a market leader staking its claim.
The release of the WH-1000XM6 in May 2025 marks a pivotal moment, re-integrating features users missed while introducing a suite of cutting-edge acoustic and processing improvements. With a new retail price set at $449.99, the XM6 is positioned as a premium offering that aims to justify its cost through superior technology and a more refined user experience. The core question for audiophiles and daily commuters alike is whether this incremental price increase translates into a generational leap in performance, specifically against its nearest and arguably strongest rival, the Bose QuietComfort Ultra.
This long-form Sony WH-1000XM6 review will meticulously dissect the WH-1000XM6, from the architectural changes in its design and the quantum leap in its noise-cancelling processor to the subtle but significant shifts in its sonic profile. We will explore the technical specifications, delve into the real-world user experience (UX), and ultimately render a final verdict on whether the WH-1000XM6 truly earns the title of “The New King of ANC,” and how decisively it manages to surpass the formidable challenge posed by the Bose QuietComfort Ultra, which itself was a highly-rated challenger upon its late 2023 release.
Sony WH-1000XM6 Review: Design, Comfort, and Everyday Use
One of the most notable and applauded changes in the Sony WH-1000XM6 addresses the most persistent critique of its predecessor: the design. The WH-1000XM5 controversially ditched the folding hinges of the XM4, resulting in a sleeker, more seamless look but a significantly larger, non-collapsible carrying case. The XM6 introduces hinged sliding arms, allowing the headphones to fold up into a much more compact size for travel, a decisive win for frequent flyers and commuters. While the overall case is still robust, this return to foldability brings a practicality that was sorely missed, demonstrating Sony’s commitment to listening to user feedback.
The aesthetic remains firmly in the minimalist, premium camp, sharing the clean lines and vegan leather padding that made the XM5 comfortable for extended use. The XM6, however, features slightly more rounded, seamless earcups, giving the build a more cohesive and robust feel. At just 252.8 grams, the XM6 remains one of the lighter flagship options available, which contributes significantly to long-term comfort, a critical factor for professional users.
The physical controls, which include a touch-sensitive control pad on the right earcup, have also been refined with a more circular shape and improved responsiveness, enhancing the overall user experience. Furthermore, the case itself has been upgraded to a new magnetic closure system, which offers a quicker and more premium feel compared to the older zipper-style cases.
The New King of Silence: Active Noise Cancellation (ANC) Performance
The true flagship feature of the WH-1000XM6 is its Active Noise Cancellation, and this is where Sony throws down the gauntlet to its rivals, particularly the Bose QuietComfort Ultra. The XM6 is engineered around the brand-new HD Noise Cancelling Processor QN3, an upgrade from the XM5’s QN1. Leaked marketing materials claim this new QN3 processor operates up to seven times faster than the QN1, enabling a sophisticated “look-ahead noise shaper” that improves digital processing.
This processing power is supported by a massive upgrade in the microphone array. Where the XM5 used eight microphones, the WH-1000XM6 now features a total of 12 omnidirectional microphones, with six of these fully dedicated to the noise-cancelling function through what Sony terms “Multi Noise Sensor Technology”. This significant increase in sensors allows the headphones to sample and analyze ambient sound much more accurately and at higher frequencies, leading to a demonstrable improvement in noise isolation.
In direct testing against its predecessor, the XM6 shows a clear edge, particularly in the difficult mid-range frequencies, which typically include human chatter and high-pitched office sounds. While the XM5 was excellent at low-frequency rumble (like airplane engines), the XM6’s improved passive isolation combined with the QN3 chip allows it to achieve up to 87% total noise reduction, a few percentage points better than the XM5’s already stellar 84%.
This marginal but important gain translates into a noticeably cleaner, quieter environment, giving the XM6 a definitive technological lead in the ANC space and making a compelling case for it being the most effective noise-cancelling headphone on the market today. The new adaptive NC optimiser further refines the experience by constantly adjusting to environmental changes as the user moves, ensuring consistent performance without the need for manual calibration.
Sonic Purity: Audio Quality, Codecs, and Immersion
While Sony’s WH-1000X series has always been revered for its ANC, the WH-1000XM6 marks a concerted effort to refine the audio quality, moving toward a more audiophile-friendly signature. The XM5 was often criticized for a slightly “V-shaped” sound profile—emphasized bass and slightly aggressive treble—which, while great for pop and EDM, sometimes lacked the refinement needed for complex classical or jazz recordings.
The XM6 addresses this with what reviewers describe as the best-sounding Sony ANC headphone to date. The new tuning features a tighter, more controlled low-end that emphasizes texture over sheer boom, providing rich, impactful bass that is better integrated into the overall mix. Furthermore, Sony has successfully smoothed out the low-end and fixed the harsh treble peaks of the XM5, delivering a warmer, more detailed, and less fatiguing listening experience. The treble extension has also been improved, offering more “sparkle and air” that contributes to a more open and lifelike sound.
The Codec and Spatial Audio Landscape
Connectivity and codec support are crucial for high-resolution audio. The WH-1000XM6 continues to champion LDAC, Sony’s proprietary codec that allows for the transmission of Hi-Res Audio content at up to 990 kbps, which remains the gold standard for high-fidelity wireless listening on Android and Sony devices. Crucially, the XM6 finally incorporates Bluetooth 5.3 with LE Audio andLC3 codec.
LC3 promises a significant improvement in audio quality and efficiency at lower bitrates, future-proofing the headphones and enabling improved bi-directional signal quality (better call quality). The notable omission, however, is the continued lack of support for Qualcomm’s aptX Adaptive codec, which is featured on the Bose QuietComfort Ultra.
For immersive audio, the XM6 carries over the popular 360 Reality Audio with head tracking, but expands its utility with a new 360 Upmix for Cinema feature. This allows the headphones to convert standard stereo content—potentially from any source—into a virtual surround sound experience, mimicking the functionality of Apple’s Spatialize Sound, and dramatically increasing the content available for spatial audio enjoyment.

Powering the Experience: Battery Life and Charging
In a world where flagship devices are constantly striving for efficiency, battery life remains one of the most practical metrics for a wireless headphone’s real-world usability. Sony has maintained the exemplary stamina of its previous generation while its competitors struggle to catch up. The WH-1000XM6 is officially rated for 30 hours of continuous playback with Active Noise Cancellation turned on. If a user opts to disable ANC, the battery life extends to an outstanding 40 hours.
This specification gives the XM6 a clear and undisputed advantage over the Bose QuietComfort Ultra, which is rated for 24 hours of playback with ANC enabled, dropping even further to 18 hours when its Immersion Mode (Bose’s spatial audio equivalent) is activated. For the long-haul traveller or the professional who spends an entire workday in an open office, this extra six to twelve hours of usable life is not a marginal benefit—it’s a massive competitive differentiator. The XM6 also retains the convenient fast-charge feature, which delivers 3 hours of listening time from just 3 minutes of charging via the modern USB-C port.
