Compare Marshall Monitor III A.N.C. Over-Ear Bluetooth Headphones vs JBL Tour One M3 Headphones

One review explicitly says the Tour One M3 supports analog audio as well as USB-C listening.

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.

Across reviews, ANC is repeatedly described as very strong and close to class leaders, even if not always the absolute best.

The software stack is broad, with tracking, spatial audio, hearing protection, and other extras called out directly.

Early impressions describe the look as slimmer, simpler, and less flashy than before.

ANC background noise is handled very well: one review cites about 30dB of reduction, while another highlights the near-absence of hiss.

ANC is effective, but some listeners are sensitive to its pressure effect or tonal influence.

Reviewers note that ANC mode changes the sound slightly, with one preferring ANC on for fullness and another preferring ANC off for tighter bass.

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

Android support is a strength, with Google Fast Pair specifically mentioned.

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 JBL app is consistently described as easy to use, feature-rich, and unusually stable.

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

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.

Wireless transmission stayed in sync with in-flight entertainment.

The headphones include ear detection for automatic pausing.

Auto power behavior prevents unwanted battery drain.

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 gets mostly positive marks for punch, resonance, and control, though not every reviewer loves the stock tuning equally.

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.

Battery life is a headline strength, with testing above 55 hours in ANC use and repeated praise for long endurance.

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 modern and clearly specified in the reviews.

Multiple reviews explicitly identify Bluetooth 5.3 support.

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 mixed but solid overall: several reviewers note sturdy construction, though premium feel is debated.

The headphones support hi-res wired playback, with the DAC and USB-C path called out directly.

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

Physical controls are generally easy to find and useful, especially the dedicated volume and pairing controls.

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.

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 case is spoken of positively and treated as a useful part of the package.

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.

Charging is quick, with full recharge around two hours and fast-charge support noted elsewhere.

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

Clamp force is repeatedly described as comfortable and well judged rather than overly tight.

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 broad, with AAC, SBC, LDAC, LC3, and related higher-end options mentioned across reviews.

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.

Long-session comfort is one of the clearest strengths, with multiple reviewers describing hours-long wear without fatigue.

Connection flexibility is a major selling point thanks to wired, wireless, and transmitter-based options.

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.

The design earns praise for cleaner lines and appealing color options, though it is not universally seen as luxurious.

The Smart Tx stands out as versatile and useful for Auracast and source bridging, even if some reviewers view it as niche.

Durability impressions are positive, including explicit notes about surviving weeks of bag carry without damage.

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

Padding is consistently praised, with comfortable faux leather and memory foam called out directly.

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

The earcups can lie flat and fold up for easier storage and carrying.

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 customization is a strength, with reviewers highlighting powerful adjustment tools including 10-band controls.

The Tour One M3 launches with an unusually dense feature set, often described as having nearly everything a buyer could want.

Find My support is explicitly listed as part of the feature set.

Reviews describe the tuning as relatively natural or accurate on suitable material, even if not all listeners rank it top of class.

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

The headband fit is flexible enough to accommodate a range of head sizes.

Headband padding is described as adequate and supportive for longer sessions.

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

Spatial and immersive modes make playback feel more enveloping, even if results vary by content and listener taste.

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.

Accessory coverage is generous, especially around the included wired connection options.

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

Instrument separation is repeatedly treated as a strong point.

The integrated microphone system is substantial, with multiple microphones built into the earcups.

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

LDAC support is repeatedly positioned as a meaningful upgrade for sound quality.

LE Audio readiness is confirmed in connection with Auracast and limited hands-on testing.

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, at least one reviewer says the sound loses composure and becomes flatter or harsher.

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.

Noise reduction for calls is a consistent strength, especially against traffic, office noise, wind, and general background sounds.

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 frequently praised, with reviewers describing the voice capture as clear, natural, and conference-ready.

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 clarity is positively described in the supplied reviews.

Multiple reviews frame the Tour One M3 as unusually compatible with a wide range of source devices.

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 present, but reliability is not spotless; one review explicitly notes stuttering.

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 strong even before ANC is engaged.

Recommendation sentiment is clearly positive overall, with one review calling the M3 an obvious choice.

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 strength because the headphones fold compactly for travel.

Perceived luxury is a weak spot: reviewers often say the finish feels more practical than premium.

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 quality is mixed, with some presets praised and others criticized as overcooked or unhelpful.

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

One video review explicitly says the earcups do not pop off for replacement, which weakens serviceability here.

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.

Sensors underpin features like auto play/pause and other smart behaviors.

Call settings include sidetone or voice-balance style adjustments rather than a one-size-fits-all approach.

Smart listening extras go beyond ANC, including personal amplification and other app-driven conveniences.

Smart pause behavior is a weak point in at least one review because it can trigger too easily.

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 handling are generally easy, from pairing to app navigation and cross-platform use.

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 earns strong praise overall, with reviewers repeatedly calling it detailed, full, and satisfying.

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.

Soundstage is generally roomy and organized, even if not always the widest in class.

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 present and usually viewed as useful or immersive, though not universally transformative.

Fit stability is good enough for walking and ordinary movement.

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

Touch controls are divisive: some reviewers found them intuitive, while others reported inconsistency or accidental triggers.

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 consistently good and sometimes excellent, with especially natural ambient pass-through noted.

Travel friendliness is a standout strength, helped by comfort, foldability, battery life, and the transmitter use case.

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

Treble and upper-register clarity are generally praised, though the exact balance depends on source and listening level.

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 central to both charging and wired digital playback.

Value impressions lean positive when the flexibility and feature set matter to the buyer, though some reviewers still note the premium price.

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 access is built into the control system.

Voice prompts and audible feedback are present during pairing and other interactions.

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

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

Reviews explicitly note the lack of an IP rating, making this a weak point for workout or moisture-heavy use.

Auto-pause exists, but one review reports occasional misses when taking the headphones off.

Wear detection resume behavior is viewed more favorably than the pause side of the feature.

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

Low weight contributes directly to comfort in multiple reviews.

Wind handling is consistently described as good for both ANC and calls.
