Marshall Monitor III A.N.C. Black Wireless On-ear headphones

Marshall Monitor III A.N.C. Black — Wireless ANC Headphones with 70-Hour Battery

The Marshall Monitor III A.N.C. Black is the brand's flagship closed-back over-ear headphone, engineered for listeners who want stage-grade isolation without sacrificing the signature Marshall punch. Active noise cancellation continuously measures ambient sound and pairs with a Transparency mode that lets announcements or conversations through on demand. Bluetooth 5.3 LE Audio-ready connectivity keeps the headphones future-proof while delivering stable multipoint pairing to phones, laptops, and TVs. Built for marathon listening sessions, road trips, and creative work where focus matters.

Standout Features: Soundstage Spatial Audio and Adaptive Loudness

What sets this model apart from typical ANC competitors are two DSP-driven technologies. Soundstage spatial audio moves the mix out of the listener's head and into a virtual room, widening instrument placement for a more cinematic feel. Adaptive Loudness monitors the audio signal and surrounding noise in real time, then rebalances bass, mids, and treble so the tonal character stays consistent at low volumes on a quiet street or at higher volumes on a busy train. With the customisable M-button, you get one-touch access to Spotify Tap, EQ presets, or the phone's voice assistant.

Technical Specifications — Drivers, Battery, and Connectivity

The acoustic platform centres on custom-tuned 32 mm dynamic drivers with a sensitivity of 117 dB SPL and 35 Ω impedance, tuned to Marshall's Dynamic Loudness curve. Battery life is the headline number: 70 hours of wireless playtime with ANC on, 100 hours with ANC off, plus a 15-minute quick charge that delivers 12 hours of listening. A full recharge takes 2.5 hours over USB-C.

Marshall Heritage and the Billie Joe Armstrong Collaboration

Marshall has spent over 60 years refining the craft of stage-ready sound, and the Monitor III A.N.C. carries that amplifier DNA into a wireless headphone format. The brand showcases the line with Green Day frontman Billie Joe Armstrong, who appears in the official campaign imagery wearing the Black colourway. Designed and engineered in Sweden and built with 66% recycled post-consumer plastic, the headphones pair Marshall's rock-and-roll visual language with sustainable material choices and a water-based, DMFa-free vegan leather alternative on the headband and case.
