Compare Marshall Monitor III A.N.C. Over-Ear Bluetooth Headphones vs Beyerdynamic Aventho 100

Reviewers generally liked the sound, describing it as pleasing, energetic, balanced, or excellent, with the strongest praise for rock and instrument-driven listening.

Most reviewers describe the sound as enjoyable, clear, and engaging, with especially strong praise from Tom’s Guide, HiFi Oasis, and HeadphoneCheck. A minority found the stock tuning merely average or dull, so EQ can make a meaningful difference.

Earpad/body-borne noise was a notable negative for one reviewer, who heard footsteps and heartbeat-like sounds.

Mechanical noise while worn is extremely low. One reviewer specifically praised the near absence of creaking or frame noise when moving the jaw.

LE Audio readiness was treated as a positive future-proofing feature by multiple reviewers.

Bluetooth LE support is absent, which one reviewer flagged as a disappointing omission from an otherwise modern wireless implementation.

Audio-video sync was a concern for gaming because one reviewer tied the lack of low-latency codecs to more noticeable latency.

Video sync is very good, especially with the low-latency option available when needed. Reviewers reported little to no lag after enabling the appropriate mode.

Wind handling was mixed: one reviewer found wind susceptibility in ANC/transparency, while another found moderate wind manageable.

Wind handling is a recurring weakness outdoors, with crackling or audible wind noise reported in both ANC and transparency modes.

The default frequency response was judged broadly listener-friendly, especially for casual listeners.

One measurement-focused review found the default response noticeably uneven and in need of EQ. It became much more natural after correction, but stock accuracy was not a strength there.

Immersive audio quality was mixed, with some reviewers enjoying the added atmosphere and others finding the effect limited or not truly immersive.

One reviewer found the stereo presentation highly immersive, with sounds moving convincingly around the listener despite the compact on-ear design.

ANC slightly affects audio performance, with one review noting higher sound-quality scores when ANC is disabled.

ANC’s effect on sound is mixed. One reviewer heard virtually no tonal change, while another found the sound more compressed and unnatural with ANC engaged.

ANC-off listening measured slightly better in one review, suggesting ANC can subtly affect the sound signature.

One reviewer found that engaging ANC left the core sound signature essentially unchanged, which makes switching noise cancellation on and off less disruptive.

ANC background noise performance was decent: one review measured strong overall noise reduction, and another said white noise was not bad.

ANC itself adds very little objectionable background noise in most testing. One reviewer heard no disturbing hiss at all, while another described only a subtle ambient 'air' rather than a true hiss.

ANC was usually judged good, solid, or decent for daily use, but several reviewers said it still trails Bose, Sony, or the top tier.

ANC is one of the most widely praised features, cutting cafe, transit, office, and steady engine noise surprisingly well for an on-ear design. It still trails the very best flagship over-ear systems, and fit can affect both comfort and effectiveness.

Microphone noise reduction was praised for handling simulated or real wind well, despite some vocal-clarity caveats elsewhere.

The microphone system does a good job suppressing background noise while keeping speech intelligible. Reviewers found it useful for calls in busier indoor and outdoor settings.

Soundstage width drew mixed reactions, from solid or opened-up presentation to narrow, cluttered, or not true-spatial enough.

Soundstage is the most consistent acoustic limitation: several reviewers call it narrow, closed-in, or intimate because of the on-ear form factor. A few still found respectable depth or width, and wired listening can open it up somewhat.

Bass was usually described as punchy or well-balanced, though several reviewers said it could use more impact, cleaner control, or stronger low-end weight.

Bass is generally a strength: powerful, full-bodied, and clean enough for pop, hip-hop, and electronic music. Some reviewers found the default low end overemphasized or muddy, while others thought it was too restrained for true bass-head impact.

Passive isolation was praised for the soft cushions and seal, which helped block noise even before ANC was considered.

Passive isolation is consistently good for an on-ear headphone and helps before ANC is even enabled. Reviewers still note that over-ear designs can seal more completely.

Codec support was a clear weakness because reviewers noted no hi-res, lossless, or low-latency codec support.

Codec support is unusually strong for this class, with AAC, SBC, aptX Adaptive, and aptX Lossless repeatedly highlighted. Reviewers see this as a meaningful advantage for compatible sources.

Value was generally fair to good, especially on sale, but reviewers noted strong cheaper or better-performing rivals.

Value is generally considered good to excellent for the combination of styling, battery life, ANC, build, and connectivity. A few reviewers still called the price high, especially when comfort or stock tuning did not suit them.

Multipoint reliability was strong where tested, with seamless switching or extremely reliable two-device use.

Multipoint works well and is usually seamless between two devices. One review found that media had to be paused on the first device before the second would play, but the broader consensus is very positive.

aptX support was criticized as absent, especially for Android or lossless-codec users.

aptX playback receives excellent marks, including praise for clean wireless sound with no obvious compression artifacts. Compatible devices can take good advantage of the headphone’s higher-quality wireless modes.

The lack of a built-in 3.5mm analog jack was a repeated drawback, even though USB-C-to-3.5mm wired listening is possible.

The 3.5mm input is widely appreciated because it allows passive listening, airplane use, and continued playback when the battery dies. Several reviewers see the wired fallback as a major usability advantage.

Water and sweat resistance was a weakness because reviewers noted the headphones are not waterproof and should avoid rain or gym use.

The IP53 rating gives useful reassurance against dust, light rain, and some sweat. Reviewers still treat it as splash resistance rather than true waterproofing.

Included accessories received praise for the attractive red-velvet case and included cables.

The accessory bundle is functional but not premium. Reviewers criticized the charging-only USB cable in one package and the dated USB-A termination in another.

The preset EQ experience was praised in one review, especially the bass boost setting for adding dynamic sound without excess bass.

At least one preset disappointed, with the bass mode described as dull and overly blunt. Custom EQ is the safer route for listeners who want to fine-tune the sound.

Wear detection auto-pause was only moderately successful, working but reacting slowly.

Automatic wear-detection pause is missing, and the reviewer who called it out viewed that omission negatively.

Ear cup rotation and swivel helped portability, though one reviewer found the twisting mechanism odd on the head.

Earcup swivel is functional but not universally intuitive. One reviewer disliked the direction the cups rotate when worn around the neck.

Cable quality received praise in one review for the black cable with brass tips and premium-feeling presentation.

Cable quality is mixed: the exposed braided wiring on the headphone is praised for improved durability, while one reviewer thought the included analog cable felt cheap.

Connectivity options were mixed: wired and wireless playback were useful, but the lack of a built-in 3.5mm jack and coiled cable hurt convenience.

Connection flexibility is excellent, spanning Bluetooth, analog 3.5mm, and USB audio in supported setups. Reviewers liked being able to choose the best connection for each device.

The carry case was usually praised as sturdy, compact, premium, or travel-friendly, though a few reviewers found it bulky or unnecessary.

The included soft pouch earns mixed reactions. Some reviewers liked its material and cable pocket, while others wanted a proper hard case or felt the bag looked too basic for the price.

Android compatibility was positive in one review that found the headphones sounded good on Android.

Android support is excellent thanks to Google Fast Pair. Reviewers reported quick recognition, one-tap setup, and reliable behavior on compatible phones.

Multi-platform compatibility was positive where tested on both iOS and Android.

The headphones work smoothly across phones and computers, including hassle-free use for video calls and everyday device switching.

Headband adjustability earned a small positive note for visible adjustment numbering.

Headband adjustment works, but the range and mechanism are not perfect. Larger heads may reach the end of the extension, and one reviewer found even adjustment a little stiff.

Features at launch were adequate but not standout, with one reviewer saying the standard feature set lacked a truly distinctive tool.

The feature set is deliberately streamlined rather than maximal, trading spatial-audio extras and other flagship features for a lower price and simpler experience.

Integrated microphone feedback was mixed, with clear/crisp quiet-room results but criticism of vocal clarity or noisy-environment performance.

The integrated microphone array performs reliably for calls and computer meetings. It captures speech clearly without requiring a boom microphone.

Replaceable pads and headband parts were a repairability plus where described.

The ear pads and headband pad can be replaced, which supports longer service life and easier maintenance.

Sustainability and repairability were praised for replaceable parts and repair-minded design, with a caveat that batteries are not user-replaceable.

Repairability is unusually strong for wireless headphones, with replaceable parts and even published disassembly guidance. Reviewers specifically praised this long-term ownership approach.

Ear cup padding was widely praised as extremely soft, plush, pillow-like, and important to comfort and sealing.

The memory-foam earpads are soft, thick, and comfortable in the positive fit case. Their cushioning helps offset the pressure inherent to an on-ear design.

Connection stability was praised as stable and high-performance in one review.

The headphones stay securely in place during normal movement despite their light weight. Reviewers generally found the clamp sufficient to prevent slipping.

One reviewer found the headphones plenty loud, with comfortable listening volume well below maximum.

The headphones can play loudly with plenty of headroom. Reviewers who tested output level found them strong without obvious strain.

Treble feedback was split between clear, impressive highs and complaints about sibilance, fatigue, or sharpness on some tracks.

Treble is mostly smooth and non-fatiguing, with several reviewers praising its clarity and lack of harshness. Others found the top end slightly dull, soft, or occasionally edgy, making this one of the more taste-dependent parts of the tuning.

Overall recommendations were positive but caveated: reviewers liked the package, especially for travel and rock-focused listening, while noting ANC, codecs, and wired tradeoffs.

Overall recommendations are strongly positive but often conditional on fit. Reviewers repeatedly advise buying for the styling, portability, battery life, and enjoyable sound, while warning that on-ear comfort should be tested if possible.

Headband comfort was praised for reducing top-of-head pressure through light weight and support-strap design.

The headband padding is generous and distributes pressure well. One reviewer reported no hot spots even during extended wear.

Midrange impressions were mixed: some praised vocals and instruments, while others heard under-emphasized mids, prominent high mids, or occasional clutter.

Midrange reproduction is usually clear, natural, and easy to follow, especially for vocals. A few reviews note some recession or resonance in the lower mids, particularly before EQ.

Transparency mode was considered usable and sometimes natural, but reviewers also noted hiss, limited realism, or weaker performance than the best rivals.

Transparency mode is generally useful and natural enough for conversations or situational awareness. Some reviewers heard muffling or wind interference outdoors, so performance is better in calm environments.

Aesthetics were distinctive and often praised, but some reviewers noted the retro Marshall look will not suit everyone.

The Aventho 100 can look distinctive without becoming flashy. One reviewer specifically praised its understated styling as a good match for buyers who want something stylish but restrained.

Premium feel was praised through richer materials, superior build impressions, and a luxurious presentation.

The Aventho 100 usually feels premium thanks to metal accents, refined styling, and solid construction. One reviewer thought the molded plastic sections kept it from fully matching its upscale appearance.

Instrument separation was a consistent strength when mentioned, with reviewers noting solid layering, instrument placement, and separation across bass, mids, and highs.

Instrument separation is usually strong enough to keep individual parts distinct, even in busy tracks. The main exception comes from reviewers who heard congestion or weaker separation when mixes became especially dense.

Travel friendliness was a major strength due to battery life, compact folding, wired flexibility, and protective case design.

Travel friendliness is a core strength: light weight, folding hinges, long battery life, and wired fallback all make the Aventho 100 easy to live with on the move.

Portability and foldability were major strengths thanks to the compact folding design and small travel footprint.

The folding on-ear design makes the Aventho 100 exceptionally portable and much easier to bag than many over-ear alternatives. Even reviewers who disliked the fit still praised the compact footprint.

Maximum-volume clarity was strong in the reviews that addressed it, with no audible or max-volume distortion reported.

Clarity remains impressively intact at very high volume, with little muddiness or distortion reported. That makes the Aventho 100 unusually composed when pushed hard.

Replaceable earpads were praised as easy to remove or replace and useful for longevity.

Earpads are easy to replace and lock securely back into place. That improves both longevity and the potential for future customization.

Clamping comfort was rated very highly, with reviewers reporting little to virtually zero pressure.

Clamping force is the product’s biggest fit wildcard. Some reviewers found it secure and comfortable, while others experienced severe pressure that made extended listening difficult.

Comfort was one of the strongest consensus wins, with reviewers repeatedly praising all-day wear, soft fit, and low fatigue.

Comfort is highly fit-dependent. Several reviewers wore the Aventho 100 for long stretches without fatigue, while others experienced sore ears, heat, or pressure after one to three hours.

Design and aesthetics were mostly praised for the distinctive Marshall look, premium detailing, and rugged styling, though taste varied.

The retro styling is one of the product’s most universal strengths, with reviewers repeatedly praising its 1970s or radio-operator aesthetic. The aluminum accents, compact proportions, and multiple finishes help it stand apart from generic wireless headphones.

Build quality was generally strong and rugged, with praise for durability and materials, offset by one report of creaking.

Build quality is consistently excellent, with sturdy metal components, robust plastics, and little creaking. Reviewers often cite construction as one of the reasons the Aventho 100 feels worth its price.

Durability over time was viewed positively because reviewers described more durable, repairable construction and long-term toughness.

Durability impressions are strong thanks to robust hinges, solid materials, and improved braided wiring. The foldable frame still feels capable of everyday commuting and travel abuse.

Weight comfort was a major strength, with reviewers repeatedly calling the headphones light for the class and easy to wear.

At roughly 220 grams, the Aventho 100 feels notably light and easy to carry. Reviewers repeatedly connect the low weight with better everyday and travel comfort.

Hinge durability was praised for being able to twist without showing signs of breaking.

Hinge construction inspires confidence, with metal structure and robust surrounding parts contributing to a durable folding mechanism.

Advanced software features were considered solid and modern, but reviewers did not see them as uniquely class-leading.

Software features are practical rather than extravagant, covering the adjustments most people are likely to use. Reviewers liked the range, though one wanted more button-mapping flexibility for ANC controls.

Bluetooth performance was praised in one review as stable and high-performance.

Bluetooth performance is consistently stable, quick to pair, and reliable across normal room or office distances. No major dropouts or connection problems were reported in hands-on testing.

EQ customization was broadly useful and responsive, though one reviewer wanted more precision than the five-band setup provides.

EQ customization is one of the most useful features because multiple reviewers improved the stock sound with it. The five-band layout is simple and effective, though a few listeners wanted finer control.

Call microphone quality received strong praise from one reviewer, especially for windy phone calls.

Call quality is a strong point overall, with voices repeatedly described as clear, full, and easy to understand. One reviewer found it merely ordinary, but most testing was distinctly positive.

Voice prompts and feedback added personality through Marshall-style guitar sounds during power and pairing.

Voice prompts are generally clear, pleasant, and useful for battery and mode feedback. One review noted that the spoken battery percentage could differ slightly from the app.

Setup simplicity received praise from one reviewer who called pairing/setup easy.

Initial setup is very easy, with quick recognition and straightforward firmware handling. Reviewers describe the onboarding process as essentially frictionless.

Button controls were a standout strength, with reviewers preferring the tactile joystick and physical buttons over touch controls.

Physical buttons are a consistent usability strength: easy to find, responsive, and more reliable than touch controls for many reviewers. A short learning period may be needed because several buttons sit close together.

The app was viewed positively for customization, controls, battery options, and a generally intuitive experience.

The companion app is broadly praised for being clean, fast, and easy to navigate. It covers ANC, transparency, EQ, button mapping, updates, and other practical settings without becoming overly complicated.

Charging was praised for fast top-ups, with reviewers citing up to 12 hours of playback from a short charge.

Fast charging is outstanding, with about 15 minutes repeatedly translating into roughly 15 hours of playback. Reviewers see this as especially valuable for travel and last-minute charging.

Battery life had the strongest agreement: reviewers repeatedly described it as class-leading, incredible, extraordinary, or far ahead of competitors.

Battery life is the clearest point of consensus: reviewers repeatedly praise the roughly 60-hour ANC-off and 40-hour ANC-on endurance. Several testers went days or a full week without needing a charge.

Auracast support was treated as a positive future-facing feature, especially for Android and LE Audio readiness.

Auto-play and wear detection worked but was slow to react in one test.

The 2025 Red Dot Design Award is repeatedly highlighted, and reviewers who discussed it generally felt the visual design deserved the recognition.

Hi-res playback support was a weakness because reviewers repeatedly noted no hi-res Bluetooth audio support.

Channel separation is clear enough to give instruments and effects distinct left-right positioning. That helps the stereo image feel organized and precise.

Detail retrieval is good but not universally class-leading. Some reviewers heard impressive fine information, while others wanted more articulation and resolution from a Beyerdynamic headphone.

The Aventho 100 is easy to drive in normal use, with its active electronics handling amplification so a powerful source is not required.

Google account integration adds useful convenience on Android by remembering the headphones for quick reconnects across compatible devices.

Glasses can worsen clamp pressure for some users. One reviewer with thin frames became uncomfortable after roughly half an hour.

Imaging is a strength, with convincing depth, stable positioning, and clear spatial movement. Even when stage width is limited, placement within that space remains precise.

LDAC was only discussed as an absent higher-quality codec, making it a codec-support weakness.

Overall satisfaction is high, with multiple reviewers calling the Aventho 100 fantastic, very good, or among their favorites. Negative reactions are driven mainly by fit and stock tuning rather than by basic functionality.

Sensor performance was a concern because one reviewer reported random wear-sensor triggers.

Sidetone can make calls feel more natural by feeding back enough of the wearer’s voice to reduce the sealed-off sensation.

Streaming service integration was praised strongly for Spotify Tap, especially for starting playback without pulling out a phone.

USB-C was useful for charging and wired listening, but reviewers criticized the one-port limitation and need for power in wired use.

Bluetooth version support was tied to a stable, high-performance wireless connection in one review.

Smart listening features were mixed: adaptive volume, Spotify Tap, and battery preservation drew praise, while missing convenience features held the score down.

Smart Pause performance was criticized for random triggering in one longer test.

Voice assistant integration has one notable software quirk: one reviewer found the assistant toggle behaved in the opposite way expected. The feature works, but that implementation was confusing.

Transient and dynamic performance is good overall, with sharp articulation in one review. Another heard some smearing when very dense, heavily layered tracks became demanding.

Gaming support is solid thanks to low-latency mode and versatile multimedia performance. One reviewer still suggested Beyerdynamic’s MMX 200 Wireless as the smarter gaming-specific choice.

Idle noise is usually very low, but the experience depends on mode. One reviewer heard virtually no hiss or hum, while another noticed audible hiss in ANC or transparency with nothing playing.

Sound leakage was viewed positively in one review because the plush ear cups helped minimize leak.

Spatial audio was divisive: some liked the extra space, but others found it unnatural, underwhelming, or below true Atmos-style experiences.

Wear detection performance was a weakness in one longer test because the sensor randomly triggered.

Sustainability materials received a modest positive note for recycled plastic use.

Long sessions can make ears hot for listeners who struggle with on-ear designs. Two reviewers specifically reported heat buildup becoming uncomfortable after extended wear.
