Marshall Monitor III ANC Black – Over-Ear Wireless Noise Cancelling Headphones, 70H ANC Battery, Soundstage Spatial Audio, BT 5.3

The Marshall Monitor III ANC is Marshall’s over-ear noise-cancelling headphone, and its headline is battery life: Marshall rates it at up to 70 hours with active noise cancelling switched on and up to 100 hours with it off. This page covers the Black finish. It folds into a hard carrying case, weighs 250 g, adds Soundstage spatial audio, and connects over Bluetooth 5.3 with multipoint.

Marshall Monitor III ANC Battery Life, in Marshall’s Numbers

Marshall lists up to 70 hours of playtime with ANC on and up to 100 hours with ANC off. Both are “up to” figures: volume, the codec in use and how much you switch modes all change the real result, but even a large margin leaves several long-haul round trips between charges. A full recharge over USB-C takes 2.5 hours, and a 15-minute top-up gives up to 12 hours of listening.

The Marshall Monitor III ANC also has a battery preservation setting in the Marshall Bluetooth app, which limits charging to protect the cell over the years. It does not charge wirelessly; charging is by cable only, and a USB-C charging cable is in the box.

Noise Cancelling, Transparency and Adaptive Loudness

A dedicated ANC button on the Marshall Monitor III ANC switches between active noise cancelling and Transparency mode. Cancelling targets the steady low drone of aircraft cabins, traffic and air-conditioning units; Transparency lets outside sound in when you need to hear an announcement or talk at a counter without lifting an ear cup.

Marshall pairs this with adaptive loudness, which rebalances the tone as your surroundings change so quiet passages stay audible, and with Dynamic Loudness, which adjusts the tonal balance at low volume so bass and treble do not fade away when you listen quietly.

Soundstage Spatial Audio and 32 mm Drivers

Inside each ear cup is a 32 mm dynamic driver. Marshall lists a frequency response of 20 Hz to 20 kHz, sensitivity of 117 dB SPL (187 mV at 1 kHz) and 35 ohms impedance. Soundstage is Marshall’s spatial audio mode: it widens the stereo image so a live recording or a film soundtrack feels less like it sits inside your head.

The M-button on the Marshall Monitor III ANC is customisable in the app: you can set it to Soundstage, to Spotify Tap or to your phone’s voice assistant. Playback is handled by the control knob on the ear cup, a control style Marshall has used on its headphones for years.

Bluetooth 5.3, Multipoint and Wired Listening

The Marshall Monitor III ANC uses Bluetooth 5.3 with a rated range of 10 metres, and multipoint lets it stay connected to two devices, such as a laptop and a phone, so a call can come through while you work. Marshall lists SBC and AAC codecs and describes the headphones as ready for Bluetooth LE Audio.

For wired listening, for example on an in-flight entertainment system, Marshall includes a USB-C to 3.5 mm audio cord. The headphones have no 3.5 mm socket of their own, so keep that cord in the case when you travel.

The Black Finish, the Fold and the Case

Black is the most understated of the Monitor III ANC colours and the safest choice if the headphones go from the office to the gym bag to the airport: marks, dust and small scuffs show far less on it than on a light finish, and it sits naturally with dark jackets, laptops and bags.

The Marshall Monitor III ANC folds at the hinges and goes into the premium hard carrying case included in the box. At 250 g it is light for an over-ear ANC headphone, which matters on a long flight where you wear it for hours. The box also contains the USB-C charging cable, the USB-C to 3.5 mm audio cord, a quick start guide and safety documentation.

Delivery, Returns and Warranty

Order the Marshall Monitor III ANC and it arrives anywhere in the UAE within 3 business days, with free delivery on orders from AED 300. It is covered by a 1-year warranty from Totot, defective or non-matching items can be returned within 14 days, and shipping damage should be reported within 48 hours of receiving the parcel.

Who This Is Not For

Marshall lists no water resistance for the Marshall Monitor III ANC, so it is not a headphone for running in the rain or heavy sweat sessions. If you stream high-resolution audio from Android and want LDAC or aptX, look elsewhere: Marshall lists only SBC and AAC.

There is no wireless charging and no 3.5 mm socket on the headphones themselves; wired use needs the included USB-C to 3.5 mm cord. Marshall does not publish the number of microphones used for calls or noise cancelling.
