The over-ear ANC market has settled into a familiar shape: Sony’s WH-1000XM6 owns the top of the pile, Bose’s QuietComfort Ultra owns the noise floor, and AirPods Max (refreshed as the H2-powered AirPods Max 2, introduced in March 2026) owns the “if you live in the Apple ecosystem” slot starting at $549. Everything else has to fight on price or personality. Marshall’s Monitor III A.N.C. has always leaned hard on personality, with gold accents, brass-script branding, and a foldable hard-case travel kit. At full price, it asked you to pay $349–$379 for it.
Price: $229.99
Where to Buy: Amazon
Not anymore. As of June 1, 2026, the Monitor III A.N.C. is $229.99 on Amazon in both Black and Cream, a $150 cut from the $379.99 list and the lowest price the headphones have hit since launch. That puts them squarely below Sony’s and Bose’s flagships and roughly half the price of AirPods Max. Right at the start of summer travel season, this is the over-ear ANC deal worth paying attention to.
Here’s the case for grabbing them now.
1. The deal, in one line
$229.99 on Amazon. $150 off list. Both colorways in stock. No coupon, no clipping, no Prime gate. The price applies to Black and Cream variants.
Marshall.com is matching the discount at $229.99, so this isn’t an Amazon-only flash, though Amazon was first to the floor. The headphones had only ever dipped to $249.99 before this, which makes the $229.99 figure a meaningful step below that earlier $249.99 floor.
2. Why this price changes the conversation
At $349–$379, the Monitor III competed on vibe. You were paying a small premium over Sony and Bose for the Marshall look, the hard case, and the rock-leaning tuning. At $229.99, it competes on value, and that’s a much harder argument for the competition to win.
| Headphone | Typical street price (June 2026) | Battery (ANC on) | Carrying case |
|---|---|---|---|
| Marshall Monitor III A.N.C. | $229.99 (sale, was $379.99) | 70 hours | Premium hard shell |
| Sony WH-1000XM6 | ~$449 | 30h rated (~32h tested) | Magnetic-clasp case |
| Bose QuietComfort Ultra (2nd Gen) | ~$449 | ~30 hours (Quiet Mode) | Soft case |
| Apple AirPods Max 2 (H2) | $549 | ~20 hours | Smart Case (cover only) |
3. Battery built for summer travel
The Monitor III’s headline spec is the one that matters most when you’re moving: 70 hours of wireless playtime with ANC on, 100 hours without (Marshall). That’s not a typo, and it’s the part Marshall has been hammering in its marketing for a reason.
For context: a Sony WH-1000XM6 with ANC on is rated for 30 hours (RTINGS measured around 32 in testing), and a Bose QC Ultra 2nd Gen does 30 hours in Quiet Mode. Marshall is still giving you more than double the Sony figure on a single charge.
What that buys you in the real world is the freedom to stop thinking about the charger. An NYC → Tokyo round-trip runs about 28 flight hours total, and the Monitor III will get you there and back on a single charge with ANC on and margin to spare for the layover. A three-day festival weekend of commute audio, hotel-room background music, and red-eye-home wind-down fits comfortably inside the same battery window, so you can leave the cable at home. And a full week of remote-work calls over Zoom, with multi-point pairing keeping the cans tethered to your laptop and phone, won’t even make the battery icon nervous.
If you’ve ever scrambled for an outlet at gate B17 because your over-ears tapped out, this is the spec that fixes that, and these belong on any short list of travel tech essentials heading into summer 2026.
4. Sound, ANC, and Transparency
The Monitor III runs Marshall’s signature tuning with Dynamic Loudness (auto-adjusts treble, mids, and bass to listening volume) and adds Soundstage spatial audio for wider, out-of-head presence. Reviewers have been consistent: Mashable singled out the midrange as quietly underrated, SoundGuys scored them a 7.5 with strong marks for tuning and battery, and WiFi HiFi flagged them as a strong pick for travelers who want fun, full sound over analytical detail.
ANC and Transparency Mode behave as you’d expect at this tier: strong on low-frequency rumble (planes, HVAC, train hum), competent but not class-leading on chatter, quick into pass-through for gate announcements. They won’t out-cancel a Bose QC Ultra, but at $229.99 they don’t need to.
5. Build, foldability, and the hard case
This is where the Monitor III pulls ahead of every flagship on the list. The headphones fold flat into a premium hard-shell case that ships in the box (not a soft pouch, not a half-case), and the case is sized to slide into a tech-backpack laptop sleeve or a personal-item bag without elbowing your charger out.
The rest of the build matches: brushed aluminum yokes, leatherette earcups, the brass-script Marshall logo on each side, and a foldable hinge that survives being unfolded one-handed at the gate. Marshall’s pitch, that the Monitor III is built tough but designed to be packed away in its hard shell case, is the rare case where the spec sheet matches the lived experience.
6. App, controls, and connectivity
The Marshall Bluetooth app is clean and on-brand. You get a 5-band EQ with genre presets and a customizable M-button on the earcup that maps to your preferred EQ, Spotify, or voice assistant. Multi-point Bluetooth 5.3 LE keeps the cans paired to your laptop and phone at the same time, and USB-C handles both charging and wired audio. Marshall ships a USB-C-to-3.5mm cable in the box, so it plays nice with the rest of your travel charging gear. Codecs are SBC, AAC, and LC3, with Bluetooth LE Audio and Auracast included for futureproofing.

The one knock that comes up in audiophile coverage is codec support. The Monitor III covers SBC, AAC, and LC3, but no LDAC or aptX Adaptive. If you’re streaming hi-res from a Sony Xperia or a FiiO DAP, that’s a real limitation. If you’re listening from an iPhone, iPad, or MacBook, it doesn’t matter; AAC is the ceiling on those platforms anyway.
7. Who should buy this, and who should skip
Buy if you’re traveling this summer and want to charge once for the whole trip, you want a premium hard case in the box, or you’re on iPhone and Mac and don’t want to pay flagship prices for flagship battery. The cream colorway is a bonus, since it rarely goes on sale, and the Monitor III slots into the daily-carry tech we’d never leave behind lineup once it’s not strapped to a suitcase.
Price: $229.99
Where to Buy: Amazon
Skip if you need the best ANC for a noisy open-plan office (Bose QC Ultra still wins there) or you stream LDAC or aptX Adaptive from Android. Monitor II A.N.C. owners can sit this out at full price, but $229.99 makes the jump to Soundstage spatial audio, longer battery, and the updated app a much easier call.
The bottom line
At $379.99, the Marshall Monitor III A.N.C. was a stylish over-ear for people who liked the look. At $229.99, it’s the over-ear ANC deal of the summer: a foldable, 70-hour, hard-case-included pair that undercuts every flagship on the shelf and matches most of them where it counts.
The sale price is the lowest these have ever been, both Black and Cream are in stock, and the timing couldn’t be better for the months when most of us actually use over-ear headphones. If you’ve been waiting for an excuse, this is it.
Price: $229.99
Where to Buy: Amazon
Buy now if you’re traveling this summer, want flagship-tier battery, and don’t need LDAC. The Amazon price is the lowest the Monitor III A.N.C. has ever been. Wait, and you’re more likely to see it climb back to $299–$349 than fall further.
