Compare Marshall Monitor III A.N.C. Over-Ear Bluetooth Headphones vs Cambridge Audio Melomania P100 SE Headphones

ANC is consistently described as solid to above average and improved versus the prior model, but most sources still place it behind top-tier Bose or Sony performance. You can adjust ANC strength in the app and set how the ANC button cycles modes; the common complaint is the lack of true adaptive ANC that auto-adjusts for you.

ANC is generally rated as strong for the price and improved versus the original P100 in several comparisons, but most reviewers still stop short of calling it class-leading versus Sony or Bose. Reviewers note multiple ANC strength levels plus quick switching via button/app, making it easy to tailor noise reduction to the environment.

Android support is good for basics (pairing features, LE Audio readiness), but Android users who want aptX or LDAC will find those codecs missing.

The Marshall app is generally well-liked for being clean and functional, giving access to firmware, EQ, ANC levels, control customization, and battery-care features.

The Melomania app is typically described as clean and functional for firmware, battery, ANC and EQ; the SE adds DynamEQ, and most find it easy to navigate.

Reviews that address aptX note it is not supported, which can be a downside for some Android users.

aptX support (including Adaptive/Lossless where source devices allow) is consistently mentioned as a key differentiator at this price.

Some reviewers flag potential latency for gaming because low-latency Bluetooth codecs are missing; wired USB-C listening is the safer option when sync matters.

Low-latency or gaming mode is mentioned as helpful for video and gaming, reducing perceived lip-sync issues to a generally acceptable level.

Bass hits with satisfying punch and extension for most listeners, but it is not a true bass-cannon and some reviewers want a stronger bass-boost or tighter control.

Bass is commonly described as impactful and powerful, especially with DynamEQ, but a few reviewers find it can get boomy or overpowering on the stock SE tuning and can vary by track.

Battery life is the headline feature: 70 hours with ANC on and up to 100 hours with ANC off is repeatedly highlighted and often backed up by real-world use. The battery is not generally described as user-replaceable; Marshall instead focuses on battery preservation settings to help extend lifespan.

Across reviews, battery life is repeatedly described as class-leading and is often verified in real use: around 60 hours with ANC on and up to 100 hours with ANC off. The user-replaceable battery is repeatedly singled out as a big longevity and sustainability win, uncommon among mainstream ANC headphones.

Bluetooth stability is generally reliable in daily use, with Bluetooth 5.3 and LE Audio readiness mentioned and few drop-out complaints.

Bluetooth connectivity is generally stable in daily use, though a few reports mention pairing friction when switching between the original P100 and the SE model.

Build quality is generally rugged and travel-ready with an emphasis on durability and repairability, though a few sources mention minor creaks or quirks.

Build quality is repeatedly described as premium and sturdy for the price, with only occasional mentions of minor creaking.

The multi-directional control knob and dedicated buttons are widely praised as intuitive, tactile, and easier to use than touch controls.

Physical button controls are consistently praised for being responsive and reliable, with clear mappings for playback, volume, ANC modes and assistant access.

Cable quality and design are serviceable, with included cables for charging and wired use, but some miss the older coiled cable style or find adapters less convenient.

Included cables are generally described as good quality and part of a well-considered accessory bundle.

The included hard case gets high marks for protection and premium feel (velvet interior, compact footprint), though a few find it thick or bulgy.

The hard travel case is frequently described as sturdy and premium, with helpful cable storage, but it can be larger than rivals because the headphones do not fold especially small.

Charging is fast and convenient via USB-C, with common claims of about 12 hours of playback from a short charge and full recharge around a couple of hours.

Fast charging is consistently highlighted as useful, with claims of a brief charge (around 5 minutes) delivering multiple hours of playback depending on ANC use.

Clamping force is generally light, with multiple reviewers reporting minimal pressure and little to no head squeeze.

Clamping force is commonly described as well-judged or slightly reduced on the SE, though a few listeners still find the fit snug.

Codec support is basic for the price: SBC and AAC are the norm, with some mentions of LE Audio/LC3, but there is no mainstream hi-res Bluetooth path.

Codec support is repeatedly cited as a strength, with broad compatibility including aptX Adaptive and aptX Lossless alongside standard Bluetooth codecs.

Long-session comfort is a standout: low weight, plush pads, and pressure-distributing headband design earn frequent praise, with only occasional complaints about heat buildup.

Comfort is generally good and improved with the SE headband updates for some users, but weight and a sometimes-stiff headband cushion can create pressure over long sessions.

Design is classic Marshall amp-inspired with textured finishes and brass/gold accents; it feels premium to fans but can be polarizing for those who prefer modern styling.

Design is usually described as clean and upscale with a new blue option, but at least one reviewer finds the headband look wide or goofy when worn.

Included wired options (USB-C to USB-C and USB-C to 3.5mm) are viewed as convenient for travel and hi-res playback without relying on Bluetooth.

Earcup padding is repeatedly described as very plush and supportive, improving seal and comfort, though it can feel warm over extended wear.

Earpads are described as plush and spacious with a good seal; a recurring minor note is that they can get warm during long listening.

Multiple reviews mention wide swivel/rotation and folding behavior that helps the headphones sit flat, pack smaller, and fit securely into the compact case.

Earcup rotation is frequently praised as flexible enough to lie flat and to fit a range of head shapes comfortably.

The 5-band EQ is responsive and helpful for tailoring the signature sound, though it is not as granular as more advanced EQ systems.

EQ control is repeatedly called effective and highly responsive, enabling meaningful tuning changes; a minor recurring gripe is limited granularity/labeling of EQ steps.

Tonal balance is often described as slightly warm rather than strictly neutral; DynamEQ and the SE retune can shift bass/treble balance, so accuracy depends on settings.

Adjustment and fit mechanisms are practical, with discrete steps and a comfort strap/headband design that helps distribute pressure and maintain a stable seal.

Adjustability is reported as sufficient for a range of head sizes, but comfort outcomes depend more on headband cushioning and weight distribution than on range.

Hinges and structure are often described as bendy and durable, but at least one review notes odd twisting behavior when you turn your head.

Hinges and moving parts are generally viewed as robust, though a small number of users report slight creaks when moving around.

Included accessories are typically strong for the category: a hard case plus cables for charging and USB-C-to-3.5mm wired listening are commonly noted.

Included accessories are routinely noted as generous for the price, especially the hard case plus multiple cables and documentation.

Instrument separation is typically above average with clear placement, but layering can compress or get congested as mixes get busier.

Instrument separation and layering are highlighted as strong, contributing to a more hi-fi style presentation and easy-to-follow mixes.

Reviews that address LDAC note it is not supported, reinforcing that these prioritize battery life and simplicity over hi-res wireless codecs.

Multiple reviewers explicitly note there is no LDAC support, which may matter to users invested in that ecosystem.

At higher volumes, many report clean playback with little obvious distortion, though a few note dynamic compression or a ceiling that flattens crescendos.

At higher volumes, clarity is generally reported as holding up well with strong dynamics and little audible strain or distortion.

Noise handling on calls is a relative strength, with several tests showing good wind and background-noise suppression, though a few note it can still struggle in very noisy offices.

Background noise reduction for calls is described as decent but behind top rivals, with some reviewers noting more noise leaks through in loud settings.

Call quality ranges from clear in quiet environments to merely decent in louder settings; it is generally usable for everyday calls but not always meeting-grade.

Call quality is usually rated as good in quiet environments and acceptable overall, though not typically viewed as best-in-class.

Midrange is generally strong for guitars and vocals, though some note either a slight mid dip (snare/vocals) or occasional mid-forward congestion on busy tracks.

Midrange is widely described as clear and well-rounded, keeping vocals present and intelligible even with elevated bass.

Multi-device use across iOS, Android and computers is reported as smooth overall, helped by Bluetooth 5.3, multipoint and app support on both mobile platforms.

Multipoint is widely reported to work well for two devices, though some wish for a device-management list and note occasional confusion when mixing wired and Bluetooth sources.

Multipoint is widely reported to work, but switching behavior is sometimes manual (for example, pausing on one device before playing on another) and auto-switching is not always present.

Passive isolation is strong thanks to a very good seal from the pads, helping block higher-frequency noise even before ANC is enabled.

Passive isolation is frequently praised thanks to the seal and pads, with some reviewers saying it blocks a lot even before ANC is enabled.

Portability is excellent: the cups swivel/fold and the headphones collapse into a very compact shape that fits a small travel case.

Portability is a mixed point: the headphones can travel fine in the included case, but limited foldability and case size make them less packable than some competitors.

Preset EQ profiles are useful and easy to swap, with bass-boost and other tonal shifts helping different genres, though a few reviewers find boosts could go further.

Preset EQ profiles are seen as useful starting points, though some reviewers say differences can be subtle and custom EQ is where the headphones shine.

Replaceable earpads are a strong point, with twist-off pads that are easy to remove and swap, supporting long-term maintenance.

Replaceable earpads are called out as easy to swap, supporting long-term comfort and maintenance.

Wear detection is available for auto play/pause, but experiences vary from fine to slightly slow or occasionally over-sensitive; it can usually be disabled.

Wear detection/sensors are generally convenient and responsive, but a few users report occasional pause/resume glitches.

Sidetone/voice passthrough during calls is mentioned as an area for improvement, with at least one reviewer wanting clearer amplification of their own voice.

Setup is straightforward and the app layout is easy to navigate, but some reviewers note missing premium conveniences like adaptive ANC behavior or deeper device management.

Setup and software are usually described as straightforward, but there are a few reports of pairing or sensor quirks that may require firmware updates or re-pairing.

Across reviews, sound is lively and engaging with a clear lean toward rock-focused tuning, but it stays enjoyable for many genres once EQ is applied. Wired listening works via USB-C using the included cable and is often described as clean and low-latency, but convenience varies because there is no built-in 3.5mm jack and some report you may need power for wired use.

Sound quality is a standout theme: detailed, engaging, and competitive with more expensive headphones; however, several note the SE stock tuning can lean bass-forward and benefits from EQ to taste. Wired listening via USB-C (and via included USB-C to 3.5mm cable) is described as a strong option, often sounding excellent and sometimes driving higher volume than Bluetooth.

Soundstage is decent for a closed-back ANC headphone but not the widest; some tracks can feel narrow or cluttered unless you use the Soundstage processing.

Many reviews describe a wide, immersive stage, though a minority characterize the presentation as more intimate than the widest options in the category.

Soundstage/spatial processing is a fun extra with adjustable room feel, but most agree it is not true immersive spatial audio and can sound synthetic on some tracks.

Spatial audio is commonly noted as absent, but several reviewers say the natural soundstage is wide enough that many listeners may not miss it.

Several reviews highlight recycled or sustainability-minded materials, positioning these as more eco-considerate than many direct rivals.

Sustainability is a recurring positive: recyclable packaging, recycled materials, and end-user replaceable battery/earpads are emphasized.

Transparency mode is usable and adjustable, but opinions vary: some find it natural and clear, while others notice hiss and weaker reproduction of deeper voices.

Transparency mode is considered usable and sometimes very natural, but multiple reviewers say it is not as airy/clear as top competitors and can suffer from wind noise.

Treble is crisp and energetic, yet several reviews mention brightness, sibilance, or fatigue on higher notes unless you tame it with EQ.

Treble performance is repeatedly praised for clarity and detail, with some noting extra sparkle/brilliance when DynamEQ is enabled.

USB-C is the single physical port for charging and wired audio, which keeps things simple but also means no dedicated 3.5mm jack.

USB-C is the core port for charging and wired audio; reviews generally like the flexibility, though some note it means there is no traditional analog 3.5mm jack on the headphone itself.

Voice assistant access is supported through the customizable button and app settings, making it easy to trigger assistants or shortcuts without touching your phone.

Voice assistant integration is available via button shortcuts and is generally reported to work as expected.

The headphones get loud without needing extreme volume, with multiple reviewers noting comfortable listening well below 100% volume.

Overall loudness is usually sufficient and can get very loud, but some reviewers still wish for a bit more headroom over Bluetooth compared to wired use.

There is no stated water or sweat resistance rating in the reviews, so these are best kept away from rain and workouts.

At least one reviewer notes there is no water/sweat resistance rating, so these are not ideal for workouts or wet conditions.

Weight is consistently called light for the class (around the mid-200g range), contributing strongly to comfort and portability.

Weight is repeatedly cited around 330g, which is heavier than many peers and can impact comfort for those sensitive to top-of-head pressure.
