  • Sennheiser Momentum 4
  • Apple AirPods Max

Key Features Mentioned

Sound Stage “Special Mode” (Marshall app)

  • Controls spaciousness and spatial audio intensity
  • Includes a large room setting
  • Spatial audio can be adjusted up to Max

App Controls & Features

  • Physical controls use ENC and M buttons (from the previous model)
  • EQ preset / spatial audio mode changes depending on app selection
  • Adaptive loudness emphasizes certain frequencies for more consistent sound across volumes

Battery Life / Performance

  • Marshall rates battery life at up to 70 hours (with ANC)

Controls / Usability

  • Uses buttons rather than touch controls
  • Easier to operate with gloves/mittens

Hardware / Comfort

  • Metal headband
  • Soft ear pads (described as among the softest)
  • Exterior uses vinyl texture / heritage design
  • Includes a premium-looking hard cover case
  • Cable runs through a “hammock design” with exposed cabling

Pros (What the Reviewer Liked)

  • Standout battery life

    • Marshall claims “up to 70 hours”
    • Reviewer observed only ~5–6% battery drain after 2–3 hours of continuous use with ANC at 50% volume, aligning with the claim

  • Build quality and design

    • Metal headband feels durable and reduces worries about headband breakage
    • Feels premium and “durable” relative to the group
    • Comfortable fit (“flush” on the head) and strong aesthetics

  • Comfort

    • Very soft ear cushions; comfortable for long wear

  • Transparency mode (relative ranking)

    • Reviewer rates Marshall transparency better than Sennheiser Momentum 4, citing more high-frequency detail

  • Sound tuning flexibility

    • Default EQ is praised for more analytical listening
    • Bass Boost adds punch without destroying clarity/separation

Cons (What the Reviewer Criticized)

  • Sound Stage effect underwhelming

    • Feels like it adds reverb, but doesn’t expand the soundstage much
    • Even with large room + spatial audio at Max

  • Noise cancelling (ANC) not best-in-class

    • Doesn’t match top competitors’ quieting performance
    • Particularly weaker versus traffic/public transport rumble
    • Reviewer suspects it may be due to softer/less dense cushions, reducing noise blocking effectiveness

  • Mic / call performance is mixed

    • Marshall mic pickup is “one of the better” performers
    • But in harsher conditions, AirPods Max and Sony XM5 reduce background noise better while keeping voice intelligible
    • In quieter conditions, it’s “pretty decent,” but not clearly #1 overall

  • Transparency can sound slightly muffled

    • Voices (including the reviewer’s own) can sound slightly muffled/un-natural

  • Warmth / heat retention

    • Soft cushions trap heat
    • Reviewer recommends breaks in hot climates (tropical conditions)

  • Exposed cables look less premium

    • “Hammock” cable routing sometimes pops out of its socket
    • Detracts from the premium feel at this price

  • Sound signature

    • Bright presentation with sizzly upper mids/highs (upper-mid emphasis)
    • Bass described as muted compared to competitors
      • AirPods Max especially noted as having very little bass
      • Other models vary, but are generally more balanced/bass-forward
    • Reviewer also frames Marshall as potentially not offering the best value, with forum discussion cited as a concern

User Experience Notes

  • Controls: Buttons are convenient for cold-weather use with gloves/mittens
  • Comfort vs heat: Cushions feel great, but may require wiping/pausing in hot climates
  • Battery experience: Excellent real-world endurance with ANC
  • Case/accessories: Hard cover case described as very premium

Comparisons Made (Unique Points)

Versus Sound Stage / Spatial Audio

  • Marshall Monitor III
    • Sound Stage mode exists and allows adjustable spaciousness/intensity
    • Reviewer says it mostly adds reverb rather than true soundstage expansion
  • Winner for sound staging: Sennheiser
    • Best separation of background detail

Versus Noise Cancelling

  • Best ANC/call noise reduction (mic background noise + intelligibility) ranked as:
    • AirPods Max
    • Sony WH-1000XM5
    • Above Marshall in harsher/noisy tests
  • Marshall performs better for human chatter in public places, but is weaker for rumbling noises

Versus Transparency Mode

  • Marshall is better than Sennheiser Momentum 4 for clarity/brightness in highs
  • Overall clearest transparency:
    • AirPods Max, Bose, Sennheiser
  • Marshall still ranks above Sennheiser

Versus Sound Quality / Tuning

  • Marshall
    • Bright mids/highs with upper-mid emphasis
    • Bass more muted unless using Bass Boost
    • Reviewer prefers Marshall over AirPods Max because AirPods Max sounds too thin/bass-light
  • AirPods Max
    • “Clean and detailed,” but too thin with low bass
    • Less “soul/character” to the reviewer
  • Sony / Bose / Sennheiser
    • More muted upper range
    • Bose described as sounding most balanced and clean in the midrange
    • Sony slightly better than Marshall (reviewer calls it only “a little better”)

Versus Build / Design

  • Marshall wins:
    • Metal headband durability feel
    • Premium heritage design
    • Best-looking/premium case
  • Downsides:
    • Exposed cables and hammock cable routing feel less premium

Versus Other Flagship Feature Sets

  • Reviewer argues rivals are more feature-rich, for example:
    • Bose QC Ultra: aptX adaptive, head tracking/momentum, aptX-related features, auto-tuning to preferences
    • Sony WH-1000XM5: LDAC support and smart features
    • AirPods Max: best seamless experience for Apple users
  • Marshall counters with:
    • Best battery life
    • Full feature access on both iOS and Android (unlike AirPods Max being most optimal in Apple ecosystems)

Ratings / Numbers Mentioned

  • Battery: rated up to 70 hours (ANC)
  • Testing estimate: after 2–3 hours continuous use with ANC at 50% volume, battery dropped only ~5–6%
  • No other explicit numeric ratings/scores were provided

Overall Verdict (Concise Recommendation)

Buy the Marshall Monitor III ANC if battery life, durable build/design, and comfortable button controls matter most to you.

Avoid or think twice if you expect:

  • Top-tier ANC
  • Exceptional soundstage expansion
  • Best-in-class mic performance in noise

The reviewer places Sony XM5 and AirPods Max above Marshall for those ANC/mic priorities, and Sennheiser above it for soundstage detail.
