Compare Marshall Monitor III A.N.C. Over-Ear Bluetooth Headphones vs Audio-Technica ATH-R70XA Headphones

Multiple reviews explicitly mention the 3.5mm connection, often alongside the included 6.3mm adapter.

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.

The understated all-black styling is viewed positively and reads as low-key rather than flashy.

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

One review explicitly lists Android support.

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.

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.

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 impressions are mixed but generally controlled rather than exaggerated: some reviews heard full, extended, punchy low end, while others wanted more richness, slam, or sub-bass weight.

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.

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

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 impressions are mixed: some reviewers call construction excellent, solid, or sturdy enough, while others think it feels flimsy or too delicate for the price.

The multi-directional control knob and dedicated buttons are widely praised as intuitive, tactile, and easier to use than touch 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 cable is often described as long and locking, which helps studio use, but some reviewers find it too long or dislike the split-cable approach.

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 carry solution is serviceable but not premium, with some reviews noting only a soft bag while another mentions a nice little carry case.

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.

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

Reviews that mention clamp describe low pressure and easy wear, especially with glasses, though the looser fit can feel unusual.

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.

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 most consistent strengths, with many reviewers saying they could wear them for hours or forget they were on.

The wired connectivity is basic but clear, with support for 3.5mm and 6.3mm use.

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.

Visually, reviewers describe them as sleek, stylish, simple, or modern, with a professional open-back look.

Multiple reviews confirm the detachable dual-sided cable is reversible or easy to remove, though not everyone likes the format.

One review explicitly questions long-term peace of mind because the thin build feels delicate.

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

Earpad comments are mostly positive, describing soft, thick, or comfortable pads, though one review found them slightly shallow.

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

One review directly criticizes the swivel as insufficient for fit and seal.

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

Reviews often describe the tuning as flat, neutral, smooth, or monitoring-oriented, emphasizing that little is overhyped.

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

Headband fit is mixed: some found adjustment simple, while others said the system did not work well or stayed too loose on smaller heads.

Comments on the headband padding are mixed but generally positive on softness; one review likes the fabric support band, while another finds the leatherette pad concept poorly executed.

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

One review says the swivel feels weak, raising concern about sturdiness around the hinge or yoke area.

The open presentation and surrounding effect are called immersive or enveloping in the reviews that address it.

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.

Reviews mention a 3m split cable, 6.3mm adapter, and carry bag or pouch as the key items in the box.

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

The headphones are repeatedly described as good at separating elements or placing sounds clearly in the stereo field.

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

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

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.

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.

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 and vocals are a recurring strength, with multiple reviews calling them clear, forward, or easy to hear, though one reviewer felt the mids could verge into shout or honk.

One review explicitly lists iOS, Android, macOS, and Windows, and another says they suit everyday listening, mixing, mastering, and gaming.

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.

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

As an open-back design, passive isolation is weak; reviewers note outside sound gets in and the headphones are poor for recording around microphones or noisy environments.

Most reviewers recommend them for mixing, mastering, or critical listening, though several add caveats about bass preferences, fit, or build.

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

Reviews frame these as home or studio headphones rather than portable ones, with explicit warnings against bus or commuting use.

Premium-feel reactions are split: one review says they feel premium, while another says the materials do not look luxurious.

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.

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

Reviews explicitly mention replaceable velour pads.

Reviews explicitly note that replacement earpads and headband parts are available.

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.

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.

One review praises the simplicity of a no-app, no-button wired design: plug them in and play.

Sound leakage is a major, repeatedly confirmed trait of the open-back design; people nearby can hear what you are playing.

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.

Reviews consistently describe the sound as natural, clear, and strong overall, with several calling it expertly tuned or great-sounding, though one reviewer found it only a fine fit for their tastes. The directly relevant wired-use review rates the sonic performance as expertly tuned.

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.

Reviewers repeatedly praise a spacious, open presentation, with several calling the stage wonderful, extended, or wider than expected.

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.

Fit stability is mixed: one reviewer says they stay on well despite light clamp, while another says they slowly slip on a smaller head.

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

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.

Reviewers repeatedly say these are bad picks for commuting or public listening because of their open-back leakage and studio-oriented use.

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

Treble is usually described as clear, crisp, and smooth rather than piercing, though a few reviews note it is restrained or intentionally smooth instead of bright.

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

Value takes context: several reviewers think the performance justifies the price, but they also stress the need for a suitable use case and, sometimes, amplification.

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

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

Several reviews say the 470-ohm design needs proper power or a headphone amp, and can sound under-driven or require higher volume to open up.

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

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

Nearly every review highlights how exceptionally light they feel, often framing that as a major comfort advantage.
