Marshall Monitor III A.N.C. Wireless Bluetooth Over-Ear Noise Cancelling Headphones with Mic - Black

The Marshall Monitor III A.N.C. wireless over-ear headphones measure the noise around you and cancel it, and Transparency mode lets the outside world back in when you need it. Custom-tuned 32 mm dynamic drivers, rated 20 Hz to 20 kHz, carry Marshall's signature sound, with Dynamic Loudness and Adaptive Loudness keeping the balance right at any volume. Soundstage spatial audio moves the music out of your head and onto a virtual stage around you.

Marshall rates the battery at 70 hours with active noise cancelling and 100 hours without it. A full charge over USB-C takes about 2.5 hours, and 15 minutes gives around 12 hours. Bluetooth 5.3 supports SBC and AAC, is ready for LE Audio and keeps two devices connected with multipoint. The control knob handles power, pairing, playback, volume and calls, a separate button switches ANC and Transparency, and the M-button opens Spotify Tap, Soundstage, your EQ presets or your voice assistant.

They weigh 250 g and fold into the carrying case. Wired listening uses the USB-C to 3.5 mm cord in the box, which plugs into the USB-C port. Marshall gives no water resistance rating.

Charge the headphones before first use with the supplied USB-C charging cable; a full charge takes about 2.5 hours. Press and hold the control knob on the right ear cup until the LED starts a slow blue pulse, then select Monitor III A.N.C. from your device's Bluetooth list. The LED stays solid white once connected. Press the ANC button to switch between noise cancelling and Transparency mode. Install the Marshall Bluetooth app to set the EQ, Soundstage and the M-button, and to get firmware updates.
