Third-party reviews

Based on 6 buyer reviews from online shops.
Reviews last updated: June 2026 · How we calculate this

What we like about Marshall Monitor

  • Iconic retro aesthetic with a premium, durable build featuring metal hinges and high-quality materials
  • Exceptional battery performance, especially on newer models (Monitor III), reaching up to 70 hours
  • Detailed sound signature with customizable EQ via the companion app to suit different genres
  • Highly portable and travel-friendly design that folds into a compact form factor
  • Comfortable over-ear fit with soft magnetic ear pads that are easy to replace
  • Intuitive controls, specifically the multi-directional gold control knob for easy navigation

What we don't like about Marshall Monitor

  • Active Noise Cancellation (ANC) is often noted as less effective compared to industry leaders like Sony or Bose
  • High retail price point makes them a less competitive value compared to some rivals in the same category
  • Proprietary app experience can be inconsistent, with some users reporting bugs or limited functionality
  • The metal hinges used for folding can pose a minor pinch hazard to fingers during adjustment
  • Missing modern features on some versions, such as the lack of a 3.5mm jack on the Monitor III model

Verdict

The Marshall Monitor III ANC is a premium over-ear headphone featuring 32mm dynamic drivers, Bluetooth 5.3 with LE Audio support, and an industry-leading battery life of up to 100 hours (70 hours with ANC). Its signature rock-inspired design incorporates rugged metal hinges, vegan leather, and a multi-directional brass control knob, while technical performance is enhanced by 'Adaptive Loudness' and a customizable 'M' button for EQ presets. Main pros include its exceptional endurance, compact foldable frame, and a clear, mid-range focused sound profile that excels with live instrumentation like rock and jazz. However, notable cons include the lack of high-res codec support, a snug fit that may cause discomfort during long sessions, and a sound signature that lacks the deep sub-bass required for genres like EDM or hip-hop.
