The Sony WH-1000X series has been the benchmark for noise-cancelling headphones since the XM3 launched in 2018. Each generation has pushed the boundary further — better ANC, better sound, better comfort. The WH-1000XM6 is the most significant leap yet, introducing an entirely new processor, a doubled microphone count, and redesigned drivers co-created with professional mastering engineers.

At ₹39,990 (20% off the ₹49,990 MRP), the XM6 competes directly with the Bose QuietComfort Ultra and Apple AirPods Max. We tested it extensively — on a flight from Bengaluru to Delhi, during daily metro commutes, in a busy café, at a WFH desk, and critically listening to music across genres — to give you the most complete picture possible.

In practical terms, this means the XM6's noise cancellation is noticeably better than anything that came before it. On the Bengaluru-Delhi flight, the engine roar was reduced to near-silence — not just muffled, but practically eliminated. Cabin announcements became barely audible whispers. In the Bengaluru metro during rush hour, conversations around us became distant background murmur.

The Adaptive Sound Control feature automatically detects whether you're walking, sitting, or commuting and adjusts the ANC intensity accordingly — you don't need to manually change settings as you move through your day. The Ambient Sound Mode, accessed by touching and holding the left earcup, lets in surrounding sound naturally when you need to hear an announcement or speak to someone, then returns to ANC mode seamlessly.

Compared directly to the Bose QuietComfort Ultra — which was previously our top ANC recommendation — the XM6's noise cancellation is marginally better in low-frequency rumble (aircraft engines, train noise) while the Bose performs slightly better for mid-frequency voices in very loud environments. Overall, the XM6 is the better all-round ANC performer.

Sony co-developed the XM6's sound tuning with professional mastering engineers — the people who finalise how albums sound before release. This collaboration shows in the results. The sound profile is balanced and accurate rather than consumer-tuned with boosted bass, making it suitable for both serious listening and casual enjoyment.

The new Carbon Fibre 30mm drivers are stiffer and lighter than conventional drivers, allowing them to move more accurately and reproduce finer details. The difference is most noticeable on acoustic music, jazz, and classical — instruments sound three-dimensional rather than flat. On Spotify or Apple Music in standard quality, the XM6 sounds excellent. With LDAC codec (available on Android and some DAPs), you get lossless-quality wireless audio — noticeably more detailed than AAC or SBC.

The Sony Headphones Connect app gives you access to a 10-band equaliser with presets and custom tuning, DSEE Extreme AI upscaling (which enhances compressed audio in real time), and 360 Reality Audio for compatible content. The EQ alone lets you tailor the sound signature to your preference — more bass for pop, flatter for monitoring, brighter for classical.

The XM6 has been redesigned from the XM5 with travel and extended wear in mind. The most notable change is the return of the fold-flat mechanism — the XM5 could only fold into a compact shape for the case, but the XM6 folds fully flat, making it easier to slip into a bag or hang around your neck.

The earcups use soft leatherette padding with a new shape that accommodates a wider range of ear sizes. We wore them for 4-hour sessions without ear fatigue or heat buildup — the earcups breathe better than the XM5 thanks to pressure relief zones in the padding. The headband is padded with similar material and distributes weight evenly across the top of the head.

At 250g, the XM6 is slightly lighter than the XM5. For reference, the Apple AirPods Max weighs 385g — considerably heavier. The lighter weight makes a meaningful difference during long commutes and flights where you're wearing the headphones for 3–6 hours continuously.

The 30-hour battery life with ANC on is sufficient for international flights, multiple commute days, or a full work week of daily use without charging. In our real-world testing with ANC on at medium intensity and Bluetooth streaming, we measured about 28–29 hours of actual playback — close to Sony's stated figure.

The 3-minute fast charge for 3 hours of playback is genuinely useful. If you're rushing to catch a flight or jumping on a long train journey and the headphones are dead, a 3-minute charge while you pack or board gives you enough for the trip. A full charge via USB-C takes approximately 3.5 hours.

With ANC off (Bluetooth only), battery extends to around 40 hours. Wired listening via the 3.5mm cable works even with the battery completely drained — useful as a last resort.

With 12 microphones — 6 for ANC and 6 for voice pickup — the XM6's call quality is the best we've tested on any wireless headphone at any price. Voices on calls are clear, warm, and natural. The beamforming microphone array focuses on your voice and suppresses background noise independently of the ANC system, so your caller hears you clearly even in a crowded café or train station.

We tested calls in a busy airport terminal and a noisy open-plan office. In both environments, callers reported our voice as clear and natural without obvious background noise intrusion. For WFH professionals on back-to-back video calls, this is a significant practical advantage over less capable alternatives.

We compared the XM6 against the two most popular premium ANC headphones in the same price range in India:

The Bose QC Ultra is an excellent alternative — better for voice-heavy ANC scenarios and slightly more comfortable for some users. The AirPods Max integrates perfectly with Apple devices but costs ₹20,000 more, weighs significantly more, and lacks LDAC. For Android users and those prioritising battery life, sound quality, and value, the Sony XM6 is the clear winner.
