Our take on the Marshall Monitor III A.N.C. Wireless Noise Cancelling Headphones

The Marshall Monitor III A.N.C. is an over-ear wireless headphone with active noise cancellation, 32 mm dynamic drivers and Bluetooth 5.3 with LE Audio readiness. Its headline figure is battery life: up to 100 hours with ANC off, far beyond most noise-cancelling rivals, and it recharges over USB-C in about 2.5 hours. The detachable 122 cm cable lets it run wired, and built-in noise-cancelling microphones handle calls. It suits listeners who want long stretches between charges and Marshall's guitar-amp styling, but its 32 mm drivers are smaller than the 40 mm units common on competing flagship headphones, so bass depth and isolation are worth auditioning against those rivals.
