The Marshall Monitor III A.N.C is a wireless over-ear headphone built around very long battery life: up to 70 hours with active noise cancelling on and up to 100 hours with it off. It has a multidirectional control knob, a customizable M button for ANC, spatial audio, Spotify Tap or EQ profiles, and a foldable frame with a rigid carry case at 250 g. It suits people who want days of listening between charges and a physical, guitar-amp-style control layout rather than a touch panel. Against rivals like the Sony WH-1000XM5 and Bose QuietComfort Ultra, it trades some of their class-leading ANC and lighter build for far longer runtime and a more distinctive look.

The Marshall Monitor III A.N.C. is a pair of wireless over-ear headphones with active noise cancelling. The noise cancelling continuously measures surrounding sound and reduces it. Transparency mode lets ambient sound back in, so you can talk to someone without taking the headphones off.
Battery life is up to 70 hours with noise cancelling on and up to 100 hours with it off. A 15-minute quick charge gives up to 12 hours of playback. The over-ear design encloses the ear and has foam earpads. The headphones fold and go into the included rigid carry case.
