Apple AirPods Max 2 vs Sennheiser HDB 630

Apple AirPods Max 2

ANC is one of the headphone's strongest cards. Apple's claimed '1.5x better' cancellation is hard to A/B but reviewers consistently rate it near the top of the class, with measured ~89% average attenuation and especially powerful low-frequency suppression.

• GSMArena calls the noise cancellation on the latest model superb — among the headphone's strongest attributes alongside build and ecosystem integration.
• SoundGuys measured the Max 2 attenuating the perceived loudness of outside noise by an average of about 89%, pulling roughly 30-40 dB through the 20-200Hz bass range — considerably stronger low-end cancellation than the Bose QC Ultra 2.
• Mark Ellis says the 1.5x-better ANC claim is tricky to A/B test, but you can settle your mind knowing you have one of the best noise-cancelling headphones on the market.
• On a plane the Max 2 cuts out around 80% of cabin noise, with the over-ear format and Apple's tuning doing a thorough job of isolating you from the outside world.
• Above roughly 1 kHz the Max 2's ANC converges with rivals and performs similarly through the midrange and highs — its clear advantage is concentrated in the low frequencies.
• Transparency mode pipes in ambient sound naturally without sounding jarring, and the H2's loud-sound reduction softens sudden noises like car horns or door slams without killing awareness.
• The loudnwireless comparison found the cheaper AirPods Pro 3 actually cancels noise more effectively in general except in the midrange where voices sit — so the Max 2's ANC lead is not absolute even within Apple's own lineup.

Sennheiser HDB 630

The HDB 630's clearest weakness relative to its $500 rivals. Reviewers agree passive isolation is good, but active cancellation is the weakest of the premium flagships — outclassed by Sony, Bose and Apple, particularly in the mid frequencies where voices and chatter sit.

• SoundGuys says the real improvement over previous Sennheisers is the passive isolation, not the ANC, and that achievable noise attenuation varies significantly with fit.
• In SoundGuys' lab test the HDB 630 reduced outside noise by an average of 83%, versus 87% for the Sony WH-1000XM6.
• RTINGS notes the very lowest rumbles of a bus or plane engine can still creep in and mid-frequency attenuation is weaker than competitors, though most everyday noise is heavily reduced.
• Crinacle calls the ANC the biggest weakness of the 630 — absolutely outclassed by the 'big three' for maximum isolation.

Apple AirPods Max 2

The build is genuinely premium — aluminium cups, a steel frame and a breathable knit-mesh headband that outclasses rivals' plastic. But Apple changed nothing in six years: at 386g these are heavy, reviewers split on whether they are comfortable past 45-90 minutes, and the Smart Case is still widely disliked.

• The aluminium chassis, breathable mesh headband and magnetic ear cushions feel very Apple, very polished and very expensive — but at 386g you absolutely notice them on your head, especially during longer listening sessions.
• GSMArena argues Apple should have addressed weight in this generation — simply making the Max 2 30% lighter would have gone a long way toward making them more approachable.
• Apple didn't change probably the number-one concern of the AirPods Max — making them more comfortable — and after years the over-the-top band still gets weighed down and heavy over time.
• Stephen Robles doesn't notice the clamping strength in the first 20-30 minutes, but it becomes uncomfortable for him around the 45-minute-to-hour mark and beyond.
• After 30 days the clamping force loosens and the earpad foam softens — one long-term reviewer rated comfort as roughly on par with the much-lighter Sony XM6 once broken in.
• The all-metal build is genuinely premium, but the design causes metal-on-metal contact that scratches the $550 headphones over time.
• The Smart Case — widely nicknamed the bra or purse case — still leaves the headband exposed and offers little real protection, and there is still no power button.
• Reddit owners of the first Max echo the disappointment that the weight and the much-mocked case carry over unchanged into the Max 2.

Sennheiser HDB 630

At ~311g the HDB 630 has plush, beefed-up padding and folds for travel, and most reviewers find it comfortable for long sessions with a lighter clamp than the Momentum 4. The recurring criticism is the mostly-plastic build, which several reviewers say feels under-premium for a $500 headphone, and ear pads that are not the most spacious for larger ears.

• At 311g (up from the Momentum 4's 295g) the extra mass is barely noticeable and comes from significantly beefed-up padding.
• The Headphone Show finds the HDB 630 more comfortable than the Momentum 4 because the clamp force is lighter and the headband distributes pressure more evenly.
• Picky Audio notes the ear pads still aren't the most spacious — ears touch the inside — but says it's easy to get used to and wear either headphone for long periods.
• One comparison reviewer found the HDB 630 needs a short break after about 2 hours of wear, where the lighter 263g Bose QC Ultra can be worn for hours without one.

Apple AirPods Max 2

The headphone's most-criticised spec. Battery is unchanged at 20 hours with ANC on — enough for a long-haul flight or a workday, but 10-40 hours short of rivals in 2026. A 5-minute USB-C charge returns about 90 minutes; a full charge takes roughly 2 hours, and ANC must be on to listen (no passive playback).

• Apple rates the Max 2 for up to 20 hours with ANC on — enough for a long-haul flight or full work day, but unchanged from the 2020 original.
• 20 hours is the lowest rating Z Reviews has measured across more than 40 wireless headphones tested, while Sony and Bose rivals now exceed 30 hours.
• A 5-minute fast charge delivers about 90 minutes of playback; a separate test gave 1 hour 39 minutes from a 5-minute charge — slightly better than Apple's claim.
• A real-world charge test on a 20W Apple adapter went 12% to 50% in about 27 minutes but slowed dramatically after that, reaching only 97% at nearly two hours — a full charge realistically takes around 2 hours.
• Standby drain is minimal — left outside the case overnight for 8 hours the Max 2 lost only 1% battery — and the case or 5 minutes of inactivity drops them into a low-power mode.
• Some owners report phantom battery drain and charging bugs 30 days in; the reviewer is confident Apple can fix the software-related issues via firmware.
• There is still no power button — the headphones can only be sent into low-power mode via the case or by leaving them idle.

Sennheiser HDB 630

An unambiguous strong point. Sennheiser rates the HDB 630 at up to 60 hours with ANC on, and independent battery tests confirm it lands in the 53-54 hour range — roughly double the Sony WH-1000XM6 and triple the AirPods Max. A 10-minute quick charge returns ~7 hours and a full charge takes only 1.5-2 hours.

• Sennheiser rates the HDB 630 at up to 60 hours of playback per charge, with a 10-minute charge providing hours of playback in a pinch.
• In SoundGuys' standardised battery test the HDB 630 lasted 53 hours 46 minutes with ANC on.
• RTINGS measured just over 54 hours with ANC on against Sennheiser's 60-hour claim, and confirmed a ~1.5 hour full charge.
• Picky Audio gave battery a 10/10 — 60 hours advertised with ANC on, 10 minutes for 7 hours of playback, and a 2-hour full charge from dead.
• Battery life drops to about 45 hours when using the BTD 700 dongle in its highest-quality mode — still far ahead of rivals.

Call quality improves with the H2 chip and Voice Isolation. Reviewers say you sound clearer on calls than on the original, and the studio-quality mic array handles FaceTime, voice memos and video conferencing well — background noise rejection in loud environments is decent but not class-leading.

• With the H2 chip the Max 2 sounds better on phone, FaceTime and video-conferencing calls, with audio quality improved whether Voice Isolation is on or off.
• A long-term owner of the AirPods Max says people consistently tell him he sounds great and clear on calls, and he has taken hundreds of calls on them.
• MacRumors notes Apple bills the mics as studio-quality, and the over-ear array gives more room for capture than tiny earbud stems.
• In a noisy Times Square test the Max 2's vocal isolation and studio-quality mics kept the speaker's voice usable, though it is a demanding environment.
• Comparison testing found the cheaper AirPods Pro 3 actually delivers cleaner mic pickup than the Max 2 in noisy conditions.

Sennheiser HDB 630

A weak spot. Reviewers say call and microphone quality is mediocre and that the mic hardware is optimized only to about 10kHz, so even the BTD 700 dongle's wideband voice codec brings little real-world improvement. Fine for casual calls, not for serious conferencing or recording.

• jakkuh's verdict: the HDB 630 is excellent unless you need to record audio with the mics — in which case just buy a dedicated microphone.
• Weekend Gear Guide explains the mic frequency response is optimized for 50Hz-10kHz, so the BTD 700 dongle's super-wideband voice codec can't deliver its full benefit.
• In a three-way call test against Bose and Sony, the HDB 630 scored equal overall — solid but not a standout for voice pickup.
• The Headphone Show says the mics aren't perfect — you'd still want a standalone microphone — but the progress is visible.
• GadgetryTech reports USB-microphone issues across platforms — including on PlayStation — that they hope a firmware update will address.

Apple AirPods Max 2

There is no standalone app — everything lives in iOS settings, where the Max 2 is unbeatable for ecosystem integration. The H2 unlocks Adaptive Audio, Conversation Awareness and live translation, and USB-C adds 24-bit lossless. The catches: AAC/SBC-only Bluetooth, no LDAC/aptX, and a degraded Android experience.

• The Max 2 has the best Apple-ecosystem auto-switching the reviewer has ever seen — switching a call from iPhone to Mac happens instantly, like clockwork.
• The H2 chip unlocks features the original lacked — Adaptive Audio, Conversation Awareness, head-gesture controls and live translation on Apple devices.
• The headphones support only SBC and AAC over Bluetooth 5.3 — no LDAC or aptX — and you can connect wired over USB-C or Apple's USB-C-to-3.5mm cable with a built-in DAC.
• Wired USB-C playback unlocks 24-bit/48kHz lossless audio and lower latency that makes the Max 2 viable for editing in Logic or Final Cut.
• On Android the experience is degraded — the digital crown's volume and the phone's volume aren't in sync, and removing the headphones won't pause playback.
• The two physical controls — a digital crown for volume and track control plus a dedicated noise-control button — are widely praised as the best controls in the headphone game because they aren't touch-sensitive.
• iOS 26 adds charge reminders, alerting you when the Max 2 drops to 15% battery.

Sennheiser HDB 630

The Smart Control Plus app is a genuine highlight — its 5-band professional parametric EQ is widely called the best in any wireless headphone. Bluetooth 5.2 with aptX Adaptive, four ways to connect, and a 30ms low-latency gaming mode are all positives, though touch controls are the slowest of the premium pack and early units had multipoint bugs.

• The Smart Control Plus app offers a professional 5-band parametric EQ — you can adjust each band's frequency and Q factor, add high/low shelves, and use undo/redo; Picky Audio calls it the best EQ available right now.
• GadgetryTech calls the parametric EQ massive — Sennheiser already makes good-sounding products, and giving listeners the keys to custom-tune is a huge advantage.
• The app handles EQ, ANC modes, firmware updates and a find-my-headphones location feature; pairing is straightforward.
• There are four ways to connect — Bluetooth 5.2, USB-C wired, 3.5mm analog, and the BTD 700 dongle — covering essentially any source.
• The BTD 700 dongle has a low-latency gaming mode that drops latency to a claimed ~30ms — good enough for lag-free video and competitive gaming.

Apple AirPods Max 2

At an unchanged $549 the Max 2 is a hard sell on pure value. Against the Sony XM6 and Bose QC Ultra 2 it trades battery and weight for build quality and ecosystem; against Apple's own $249 AirPods Pro 3 reviewers question why anyone outside the ecosystem would pay more than double.

• Z Reviews argues the premium build and Apple-ecosystem connectivity make the Max 2 look like decent value at $50 cheaper than the plasticky Sony XM6 and Bose QC Ultra 2 flagships.
• The Sony XM6 costs around $400 new and offers 30 hours of battery — 10 more than the Max 2 — making it the more practical daily driver despite a less premium build.
• 9to5Mac calls the AirPods Max 2 'more of a status symbol than an actual product worth $550', recommending the AirPods Pro 3 for most Apple users instead.
• The Bose QC Ultra 2 offers 30 hours of battery for about $100 less and is roughly 120g lighter, beating the Max 2 on the two specs that matter most for travel.
• Tom's Guide concludes you are paying for the Apple ecosystem, the design and a bit of status — the value case rests almost entirely on owning other Apple devices.
• Reddit owners repeatedly say $549 is hard to justify for headphones used only part-time, with several preferring Bose for comfort-plus-ANC at a lower price.

Sennheiser HDB 630

At a $489-500 launch price the HDB 630 sits exactly alongside the Sony WH-1000XM6, Bose QC Ultra and AirPods Max. Reviewers frame it as the pick for buyers who prioritise sound, battery and wired flexibility — and the wrong pick for buyers who want the best ANC or a luxe build.

• SoundGuys: while it doesn't take the crown for best ANC ever tested, the HDB 630 sounds far better than the Sony WH-1000XM6, the Bose QC Ultra and the AirPods Max.
• The HDB 630 launched at $489-500, the same bracket as the Sony XM6, AirPods Max and B&W PX7 range.
• The Headphone Show recommended the HDB 630 as the ANC headphone to get in its buying guide — though it concedes the Bose QC Ultra is more impressive in certain ways, making it a genuinely difficult choice.
• Crinacle loves the 630 as an audiophile but cautions that the average buyer who prioritises ANC should still consider the big three.
