Verdict

The Marshall Monitor III A.N.C. are lightweight (250g) over-ear headphones featuring 32mm dynamic drivers, Bluetooth 5.3 with LE Audio/Auracast support, and a frequency response of 20Hz–20kHz. Its standout characteristics include an industry-leading battery life of up to 70 hours with active noise cancellation (ANC) and 100 hours without, along with a rugged, foldable design and a customizable 'M-button'. Major pros are the extreme portability, class-leading stamina, and tactile control knob, though cons include the lack of high-res codecs (LDAC/aptX), noise cancellation that trails behind top-tier rivals like Bose or Sony, and the requirement for the headphones to be powered on even when used with a wired connection.

What customers like about Marshall Monitor III?

  • Exceptional battery life, offering up to 70 hours with ANC and 100 hours without
  • Iconic, lightweight design with soft, high-quality leatherette and gold accents
  • Incredibly comfortable for long sessions, even for users with glasses or piercings
  • Highly portable and durable with a robust folding mechanism and a compact, premium hard case
  • Intuitive physical controls featuring a multi-directional gold joystick and customizable buttons
  • Solid sound performance, particularly suited for rock, pop, and vocal-heavy genres
  • Useful app features including a 5-band EQ, spatial 'Soundstage' mode, and battery preservation tools

What customers dislike about Marshall Monitor III?

  • Active Noise Cancellation (ANC) is decent but falls short of flagship competitors like Bose and Sony
  • Transparency mode can introduce a noticeable background hiss or static
  • Bass response may feel under-emphasized or 'polite' for listeners who prefer deep, thumping lows
  • Missing a standard 3.5mm jack; wired listening requires a USB-C adapter and the headphones must be powered on
  • Lacks support for high-resolution Bluetooth codecs (limited to SBC and AAC)
  • Some users report heat and moisture buildup around the ears during extended wear
  • Microphone performance can struggle with vocal clarity in loud or windy environments
