The launch of the Sony WH-1000XM6 on May 15, 2025, represents more than a routine product update; it marks the emergence of the new king in the active noise-cancelling (ANC) headphone market.
Sony WH-1000XM6 merges the acclaimed portability of the WH-1000XM4 with the advanced technological platform introduced by the WH-1000XM5. This positions the XM6 as the market's most versatile “all-rounder” for a core user base of frequent travelers and hybrid professionals.
This Bluetooth headphone guide explains the history of Sony WH-1000XM series, new features of the Sony WH-1000XM6 (vs XM5). It also compares Sony WH-1000XM6 with other flagship ANC headphones (Bose QuietComfort Ultra, AirPods Max, and Sennheiser Momentum 4). This guide helps you explore the Sony WH-1000XM6 from all perspectives and answer questions you may have, such as whether you should upgrade from the XM5 to the XM6, and which ANC headphones are the best choice.
Please note that the Sony WH-1000XM series is an over-ear headphone, while the WF-1000XM series (e.g., WF-1000XM6, or WF-1000XM5) is an in-ear wireless bud. This post discusses only the WH-1000XM series.
The Evolutionary Trajectory: From MDR-1000X to WH-1000XM5
To fully appreciate the design choices of the WH-1000XM6, it is essential to understand the iterative progression of the series. Each generation introduced key technologies and addressed specific shortcomings, creating a clear evolutionary path.
MDR-1000X (2016): The Origin
The original MDR-1000X established the foundational formula for the series: a combination of premium build, highly effective ANC, and a suite of advanced software features.
It introduced innovations like DSEE HX audio upscaling, touch-capacitive earcup controls, and the novel “Quick Attention” mode, which allowed users to momentarily hear their surroundings by cupping a hand over the earcup.
With a 20-hour battery life, it was a strong contender, though its polyurethane foam earpads were noted as less plush than competitors. Its primary weaknesses were finicky touch controls, the lack of a multi-device Bluetooth connection, and a launch price that was higher than the then-dominant Bose QuietComfort 35.
WH-1000XM2 (2017): Iteration and Integration
The XM2 was a model of refinement, focusing on software and battery life rather than a physical redesign. Its most significant improvement was the integration with the Sony | Headphones Connect app, which enabled features like atmospheric pressure optimization for flights and customizable equalization (EQ).
Battery life was extended to an industry-leading 30 hours with ANC enabled, a benchmark that would hold for several generations. The XM2 also expanded its high-resolution audio support by adding the aptX HD codec, a key feature for Android users at the time. However, it retained the same physical design as its predecessor, including concerns about the long-term durability of its plastic components.
WH-1000XM3 (2018): The Leap Forward
This generation marked the most significant technological jump in the series' history, centered on the introduction of the dedicated HD Noise Cancelling Processor QN1. This new chip dramatically improved ANC performance, allowing Sony to definitively surpass its rivals in noise attenuation.
The XM3 also modernized its hardware by adopting USB-C for charging, which enabled a new quick-charge feature providing five hours of playback from just a 10-minute charge. Ergonomics were substantially improved; the headphones were 20% lighter than the XM2, with deeper earpads and a redesigned headband that made them far more comfortable for extended use. While call quality remained a weak point, the sound was praised for being more natural and detailed.
WH-1000XM4 (2020): Refinement and Intelligence
Building on the successful XM3 platform, the XM4 focused on intelligent features and connectivity. The headline upgrade was multipoint Bluetooth pairing, allowing a simultaneous connection to two devices—a critical quality-of-life improvement for users switching between laptops and phones.
It also introduced AI-driven features like Speak-to-Chat, which automatically pauses music when the user begins talking, and a proximity sensor for auto-play/pause functionality. The audio processing engine was upgraded to DSEE Extreme.
In a controversial move, Sony dropped support for aptX and aptX HD, pivoting entirely to its proprietary LDAC codec for high-resolution wireless audio. This decision solidified a strategic pattern: prioritizing Sony's own technology stack over universal standards (this is Samsung's approach to its Seamless Codec in their devices). While LDAC offers superior bitrate on compatible devices (primarily Android), this move alienated some users who relied on aptX.
WH-1000XM5 (2022): The Failed Redesign
The XM5 was a radical aesthetic and structural departure. It featured a “noiseless,” unibody design with a non-folding headband and smooth, stepless sliders. This was polarizing; while praised for its minimalist look, the loss of foldability and the resulting larger case were seen as major functional regressions for travelers.
Internally, it introduced a new, smaller 30mm carbon fiber composite driver, engineered for improved high-frequency clarity. The processing architecture was upgraded by pairing the Integrated Processor V1 (from the WF-1000XM4 earbuds) with the existing QN1 chip. The microphone count was doubled to eight, leading to a significant improvement in both ANC and voice call quality, a long-standing weakness that was finally addressed. However, the new plastic construction was a step down in premium feel from the XM4, and the shallower earcups proved less comfortable for some users.
This history reveals Sony's consistent strategy of leveraging its vertical integration, from music studios to hardware. The deliberate shift away from aptX in the XM4, continued in the XM5 and XM6, shows a commitment to its own ecosystem. Sony is not trying to build the most universally compatible headphone, but rather the best Sony headphone, betting that the performance benefits of its proprietary stack (LDAC, DSEE, 360 Reality Audio) outweigh the convenience of third-party codecs for its target audience.
In-depth Analysis: WH-1000XM6 vs. WH-1000XM5
The WH-1000XM6 is not merely an incremental update; it is a direct and comprehensive response to the functional and technical landscape established by the WH-1000XM5. The changes, while subtle in appearance, are significant in practice.
Design and Ergonomics
The most celebrated change is the return of the foldable design. The XM6 re-implements the dual-hinge system of the XM4, allowing the headphones to collapse into a compact form for travel. Critically, the new hinge incorporates a visible metal reinforcement component, suggesting a direct effort to improve long-term durability, a concern with past plastic hinges. This change enables a smaller, more practical carrying case that now closes with a magnetic clasp instead of a zipper, allowing for quicker access.
Ergonomic refinements are also notable. The headband is wider and flatter than the XM5's, designed to distribute the 254-gram weight more evenly for enhanced comfort on long sessions. A slight increase in clamping force has been applied, which serves the dual purpose of creating a more secure fit and improving passive noise isolation by ensuring a tighter earpad seal.
Usability has been improved through small but meaningful tweaks: the earpads are now user-detachable for easy replacement, and the power button has been redesigned to be circular and recessed, making it physically distinct from the adjacent ANC/Custom button to prevent accidental presses.
The QN3 Engine and Driver
At the heart of the XM6 is the new HD Noise Cancelling Processor QN3. Sony claims this chip is seven times faster than the QN1 processor used in the XM5, providing the computational headroom for all subsequent performance gains. This power is fed by a vastly expanded sensor array. The microphone count has increased by 50%, from eight on the XM5 to twelve on the XM6 (six per earcup), providing a richer stream of environmental data for the ANC and voice call algorithms to process.
The driver unit, while maintaining the 30mm diameter and carbon fiber composite material of the XM5, has been re-engineered. It features a more rigid dome and a newly developed voice coil structure. This was done in collaboration with mastering engineers from studios like Sterling Sound to achieve clearer vocals, improved instrumental definition, and smoother high-frequency reproduction.
Performance
The new hardware translates directly into superior performance. The combination of the QN3 processor, 12-mic array, and improved passive isolation has led multiple reviewers to declare the XM6's Active Noise Cancellation as the new market leader, marginally surpassing the formidable Bose QuietComfort Ultra. The system is now termed “adaptive ANC optimization,” which dynamically adjusts to a wider range of frequencies in real-time, proving particularly effective against complex, non-constant noises like human voices.
Audio fidelity is described as more detailed, dynamic, and precise than the XM5. The new driver tuning delivers cleaner, more impactful bass and gives vocals more presence and clarity. However, the soundstage remains relatively narrow compared to rivals like the AirPods Max, presenting a more focused and intimate “in-studio” sound rather than a wide, concert-hall presentation.
The most dramatic improvement is in voice call quality. The XM6 employs an advanced six-microphone AI-based beamforming system (up from four mics on the XM5) dedicated to isolating the user's voice. This results in crystal-clear calls, with background noise being almost completely silenced, a significant step up from the already-capable XM5.
Connectivity and Feature Set
The XM6 introduces several key features. It supports Bluetooth 5.3 with LE Audio and Auracast (as introduced in Samsung Galaxy Buds 3 Pro), making it one of the first mainstream headphones ready for the next-generation Bluetooth broadcast standard for public spaces—a significant future-proofing measure.
A major functional deficit of the XM5 has been rectified: the XM6 can now be used while charging via USB-C. Real-world battery testing also indicates a tangible improvement.
However, Sony's strategic omissions persist. There is still no support for any variant of Qualcomm's aptX codec, including aptX Adaptive, forcing users to rely on SBC, AAC, or Sony's own LDAC.
Furthermore, the USB-C port is for charging only; there is no support for direct digital audio input, a feature desired by some audiophiles and offered by competitors like the Sonos Ace and iPod Max (with recent firmware update). Finally, the headphones still lack an official IP rating for water or sweat resistance.
These choices reveal a clear prioritization of mainstream, future-facing technologies like Auracast over niche, audiophile-demanded features like USB-C audio.

However, this comes at the cost of extreme weight (385g vs. 254g) and poor portability.
The XM6 surpasses the aging AirPods Max in nearly every objective performance metric: more effective ANC, vastly superior call quality, and significantly longer battery life (30+ hours vs. 20 hours).
Verdict:
- Choose the Apple AirPods Max only if you are deeply embedded in the Apple ecosystem and prioritize premium build materials over performance, portability, and price.
- For everyone else, the Sony WH-1000XM6 offers objectively better performance and cross-platform functionality at a lower price.
Sony WH-1000XM6 vs. Sennheiser Momentum 4 Wireless: The All-Rounder vs. The Endurance Audiophile
The Momentum 4's primary strength is its staggering 60-hour battery life, which is nearly double that of the XM6 and makes it the champion for users who despise charging. It is also widely regarded as having the best out-of-the-box sound quality, with a more balanced, audiophile-friendly tuning and comprehensive codec support, including aptX Adaptive. However, this comes at a cost.
The XM6 is significantly better at noise cancellation and call quality; the Momentum 4's ANC is competent but is a clear tier below the elite performance of Sony and Bose.
Verdict:
- Choose the Sennheiser Momentum 4 if your absolute top priorities are battery life and out-of-the-box sound fidelity, and you can accept good-but-not-great ANC.
- Choose the Sony WH-1000XM6 if you require top-tier ANC and call clarity for use in noisy environments.
