Sony’s WH-1000XM6 improves on already-class-leading noise cancellation by adding Integrated Processor V2 — a chip that analyses ambient sound 700 times per second and adjusts ANC parameters in real time, rather than the fixed profiles of its predecessor. The result in a busy coffee shop or on a commuter flight is a quieter baseline noise floor with fewer audible artefacts when someone walks past or a door slams nearby. It’s not a small improvement.

Sound quality continues the warm, controlled tuning that Sony’s XM line has been known for: bass that extends deeply without becoming muddy, mids that don’t recede when noise cancellation activates, and highs that are smooth without being rolled off. LDAC support at 96 kHz/24-bit resolves the detail in high-resolution files on Android. Speak-to-Chat automatically pauses playback when you start talking — a feature that sounds minor but becomes indispensable quickly.

Thirty hours of battery life with ANC on (40 without) means a transatlantic flight and a full work day before you need a cable. The folding design is compact for a full-size over-ear headphone. USB-C quick charge delivers 3 hours of playback from a 3-minute charge. This is the headphone we recommend to most people most of the time.

Bose QuietComfort Ultra Headphones /product/bose-quietcomfort-ultra/ /product/bose-quietcomfort-ultra/#comments Sat, 16 May 2026 09:56:24 +0000 /product/bose-quietcomfort-ultra/ Bose Immersive Audio and CustomTune technology personalise the sound to your exact head shape — every listening environment, tuned just for you.

The Bose QuietComfort Ultra Headphones are the most thoughtfully personalised pair of ANC headphones on the market. CustomTune uses the built-in microphones to measure your specific ear canal shape on first wear and calibrates both the ANC filter and the sound tuning to your anatomy — a feature that Bose calls “personalised” in their marketing and that genuinely delivers different (and measurably better) results for different listeners. In A/B testing against the XM6, the Bose sounds more spatially accurate while the Sony reaches a quieter floor.

Bose Immersive Audio delivers a convincing stereo widening effect that works especially well for binaural recordings and spatial audio tracks. It’s not a substitute for real spatial audio rendering, but it transforms compressed pop mixes into something that feels more expansive. The 24-hour battery with ANC enabled is shorter than Sony’s, but the build quality — padded headband, protein leather memory foam ear cushions, and a metal hinge — justifies the premium feel at this price.

The app gives access to eleven levels of ANC and Transparency mode independently adjustable, a shortcut button fully customisable, and Aware mode that adds wind noise reduction. Multipoint pairing works with two devices simultaneously, and the handoff between laptop and phone as you move between them is the most reliable of any pairing we’ve tested.

Driver Full-range driver with Bose custom acoustics (undisclosed size)
ANC CustomTune personalised ANC + EQ, 11 adjustable levels
Codec AAC, SBC; aptX not supported; multipoint (2 devices)
Battery 24 hrs (ANC on); 15 min → 2.5 hrs quick charge
Connectivity Bluetooth 5.3 LE, 2.5mm to 3.5mm analogue cable included
Weight 8.85 oz (250 g)
Spatial Audio Bose Immersive Audio — head-tracking personalised stereo widening

Apple AirPods Pro 2 (USB-C) /product/apple-airpods-pro-2-usbc/ /product/apple-airpods-pro-2-usbc/#comments Sat, 16 May 2026 09:56:24 +0000 /product/apple-airpods-pro-2-usbc/ Up to 2× more active noise cancellation than the original AirPods Pro, with Adaptive Audio that smoothly blends ANC and Transparency for real life.

AirPods Pro 2 with USB-C remains the best earbuds for iPhone users despite being over a year on the market — Apple has improved the firmware iteratively to add personalised volume, Adaptive Audio (a blend of ANC and Transparency that adjusts automatically based on ambient sound), and a Conversation Awareness mode that lowers music and boosts voices when you start talking to someone. These features arrived as free updates and continue to refine the experience without new hardware.

The H2 chip processes ANC at 48,000 times per second using two mics per bud, with adaptive adjustment across the frequency spectrum. In the environments where earbuds struggle most — outdoor wind, HVAC units, traffic — the AirPods Pro 2 perform at least as well as any over-ear ANC headphone and significantly better than competing earbuds. Sound quality is warm and full for earbuds at this size; the custom Apple driver with a new low-distortion amplifier is a meaningful upgrade over the original Pro.

Up to 6 hours of listening with ANC on per charge (30 hours total with the case), find-my-device precision, Qi2 wireless case charging, and IP54 water resistance on both buds and case make AirPods Pro 2 a “buy once, use for years” proposition for anyone deep in the Apple ecosystem.

Sony WF-1000XM5 Earbuds /product/sony-wf-1000xm5/ /product/sony-wf-1000xm5/#comments Sat, 16 May 2026 09:56:24 +0000 /product/sony-wf-1000xm5/ The smallest, lightest premium ANC earbuds Sony has ever made — with Integrated Processor V2 that analyses and adjusts noise cancellation 700 times per second.

Sony made the WF-1000XM5 28% smaller than the XM4 without reducing driver size — a meaningful achievement that makes them competitive with the AirPods Pro in an ear canal without the wing-tip stabilisers that many users find uncomfortable. The 8.4mm driver with Integrated Processor V2 performs ANC at the same 700-adjustments-per-second rate as the WH-1000XM6 over-ear headphones, adapting to ear fit and seal quality continuously.

LDAC support at 96 kHz/24-bit remains the headline spec for Android users connecting to a high-resolution source. The sound signature is tuned similarly to the XM6 — extended bass, controlled mids, smooth highs — but the smaller driver produces a slightly narrower soundstage that over-ear models handle better on complex orchestral recordings. For pop, electronic, and podcast listening, the WF-1000XM5 excels.

Eight hours per charge (24 with the case), wireless charging case with Qi, and IPX4 water resistance for workouts round out a complete package. Call quality is improved over the XM4 with a dedicated microphone beam-forming algorithm that isolates voice from background noise effectively on crowded streets.

Driver 8.4mm full-range, LCP diaphragm
Chip Integrated Processor V2 (V2 + QN2e)
ANC Adaptive Sound Control, dual noise-sensing mics per earbud
Codec LDAC, AAC, SBC; multipoint (2 devices)
Battery 8 hrs (ANC on) per bud; 24 hrs with case; Qi wireless charging case
Connectivity Bluetooth 5.3; IPX4 (buds + case)
Weight 0.19 oz (5.4 g) per earbud
Controls Touch sensor per bud, customisable via Sony Headphones Connect app

Sennheiser Momentum 4 Wireless /product/sennheiser-momentum-4/ /product/sennheiser-momentum-4/#comments Sat, 16 May 2026 09:56:24 +0000 /product/sennheiser-momentum-4/ Sixty hours of playtime and a finely tuned adaptive ANC system — Sennheiser's audiophile DNA in an everyday carry headphone.

Sennheiser’s Momentum 4 Wireless makes a case that 60 hours of battery life is a feature worthy of the headline spec. In practice, it means you charge the headphone once a week or less, and never negotiate a packed bag with a cable. The adaptive ANC system uses Sennheiser’s updated algorithm to reduce ambient noise to a level competitive with Sony and Bose at a price point that undercuts both, particularly when on sale.

Sennheiser-tuned 42mm transducers deliver the brand’s characteristically accurate sound: detailed, well-imaged, and less “processed” than the Sony house sound. Hi-Res Audio certification and Qualcomm aptX Adaptive codec support at 24-bit / 44.1kHz make it one of the better-sounding over-ear options in this price bracket for lossless streaming on Android. iPhone users get AAC, which is limited to CD quality but sounds noticeably better on these drivers than on budget alternatives.

The folding build is lighter than its 9-ounce weight suggests — an ergonomic headband distributes pressure evenly and makes 4+ hour sessions comfortable in a way that heavier Sony and Bose models are not for everyone. The companion app offers a 5-band EQ, automatic on/off based on head detection, and a side-tone level control for voice calls.

Driver 42mm dynamic driver, Hi-Res Audio certified
ANC Adaptive ANC with 4 mic array; 3 ANC levels adjustable
Codec aptX Adaptive (24-bit/44.1kHz), aptX, AAC, SBC; multipoint
Battery 60 hrs (no ANC) / 30 hrs (ANC on); USB-C fast charge
Connectivity Bluetooth 5.2, 2.5mm analogue input
Weight 8.99 oz (255 g)
Foldable Yes — slim folding design, soft-shell case included
Controls Buttons (no touch); voice assistant support, Sennheiser Smart Control app
In the box Momentum 4 Wireless, Soft case, USB-C cable, 2.5mm to 3.5mm cable
