The Marshall Monitor III ANC is a triumph of design and endurance, crafted for those who want their audio experience to last. Drawing inspiration from Marshall's legendary amplifiers, these headphones feature a classic grunginess with a durable, foldable build that is designed to survive the rigors of the road. They come paired with a compact, red-velvet-lined hard case that mimics a miniature guitar case, ensuring your gear stays protected between sessions. Performance is where the Monitor III truly excels, boasting a stupendous battery life of 70 hours with Active Noise Cancellation (ANC) on, and an incredible 100 hours with it off. For those in a rush, a quick 15-minute charge provides 12 hours of playtime. The audio experience is powered by 32mm drivers that deliver a well-balanced, crisp tone, further enhanced by the Marshall Bluetooth app. Users can activate 'Soundstage' spatial audio to create a live ambiance or use 'Dynamic Loudness' to automatically adjust treble, mids, and bass based on the volume and environment. Control is tactile and intuitive, eschewing touch-swipes for a multidirectional control knob and a customizable 'M button' that can be programmed for voice assistants, EQ settings, or Spotify Tap. The ANC system offers three modes—on, off, and transparency—allowing you to either immerse yourself in music or stay aware of your surroundings. The addition of Bluetooth 5.3 and LE Audio makes these headphones Auracast compatible, preparing them for the next generation of audio sharing. Sustainability is woven into the build, with 66% of the plastic being GRS certified post-consumer recycled material. The iconic vegan leather has been replaced with a durable, water-based, DMFa-free alternative. While they sit in the high-end price bracket, the combination of rugged construction, immense battery life, and a refined musicality makes the Marshall Monitor III ANC a compelling choice for music lovers and frequent travelers alike.
