Features

Overview: The Marshall Monitor III A.N.C wireless over-ear headphones are lightweight and can be used with or without an audio cable. The built-in rechargeable battery gives you up to 100 hours of playback time on a single charge. You can listen via Bluetooth 5.3, or plug the headphones into your audio source. The ear cups are hinged so you can fold them into a compact size for storing in the included, red velvet-lined hard zippered case. The Monitor III A.N.Cs come with a 4\’ audio cable and an 8" USB charging cable.

Drivers: The Monitor III A.N.C headphones are equipped with 32mm, custom-tuned dynamic drivers that feature a wide frequency response. The headphones feature Adaptive Loudness that dynamically adjusts the bass, mids, and treble to your surroundings to deliver the best Marshall Signature sound, no matter where you are.

Bluetooth: The Marshall Monitor III A.N.C over-ear headphones have Bluetooth 5.3 to let you listen wirelessly up to 30 feet from your music source (mobile phone, tablet, computer, or other Bluetooth music player). It is compatible with SBC and AAC codecs. The headphones are Bluetooth LE Audio-ready, so they\’re future-proofed for Auracast™ audio sharing technology. The headphones also support multi-point connectivity, allowing you to pair with two wireless sources simultaneously and easily switch between them.

Active Noise Cancelling (A.N.C.): The headphones are equipped with Active Noise Cancelling which electronically blocks ambient noise by applying an opposite audio signal, leaving just your music. For those times when you want to remain aware of your surroundings, you can activate Transparency Mode to let the outside world back in. The A.N.C. button, located on the left earcup, lets you toggle between Active Noice Cancelling and Transparency Mode.

Controls: The right earcup features a gold control knob that enables you to power the headphones on or off, pair with your smartphone or Bluetooth audio source, control your music playback, and answer/end/reject phone calls. It can also control the volume. Also on the right earcup is the customizable M-button which gives you instant access to a favorite feature or function. By default, the M-button is programmed to launch Spotify Tap. You can customize the functions of the M-button in the Marshall Bluetooth app. The A.N.C. button (described above) is located on the left earcup.

Spotify Tap: Spotify Tap allows you to instantly begin listening to your favorite music with the press of a single button (the M-button on the Monitor III A.N.C headphones). There\’s no need to touch your phone or music player, or open the Spotify app to start your music. Spotify Tap lets you jump back in to where you left off, or start a new recommended selection by tapping the button again. To enjoy Spotify Tap, you must first setup the feature in the Marshall Bluetooth app.

Soundstage: The Monitor III A.N.C. headphones features Marshall\’s new Soundstage spatial audio technology for a more immersive listening experience. Soundstage creates a virtual room around the listener, taking the music outside of your head.

Battery: The built-in rechargeable battery provides 70 hours of playback time with A.N.C., and 100 hours without A.N.C. on a single charge. The battery can be charged in approximately 2.5 hours when plugged into a USB power source via the included USB-C cable. A 15-minute quick charge provides enough power for 12 hours of wireless playback time.

Audio Cable: The Monitor III A.N.C headphones come with a 48" audio cable with a 3.5mm plug for connecting to your audio source. The USB-C port on the right ear cup can be used for wired listening or charging the battery.

Marshall Bluetooth App: Although you can use the Monitor III A.N.Cs without an app, the companion Marshall Bluetooth app (iOS 14.0+, Android 7.0+) provides additional support for your headphones. With the app, you can check the battery status of the headphones at a glance, and customize the sound with the equalizer. The app lets you configure the M-button to your frequently-used functions. You can select a preset EQ curve or create and save your own. When firmware updates become available, you can update the headphones through the app.
