100 Hours of Flexible Marshall Musicality
It's difficult to imagine a name more intrinsic to the foundational DNA of rock 'n' roll than Marshall. Their Monitor III A.N.C. headphones are masterfully crafted with every ounce of the cutting-edge ethos that has made Marshall a household name, well beyond the realms of stage-blazing sound. The Monitor III A.N.C.'s namesake Active Noise Cancellation gives you 70 hours of isolated hi-fi listening. However, the playback versatility is what has Sweetwater's sound hounds most impressed. Not only can you deactivate the noise-canceling feature to extend your battery life to 100 hours between charges, but the onboard Transparency mode actively measures the sounds around you, making real-time adjustments that balance the best of both worlds. Adaptability abounds with Adaptive and Dynamic Loudness technologies, while cutting-edge Bluetooth 5.3 LE audio, multi-point connectivity, and Soundstage spatial immersion serve up ferociously future-proofed firepower all day long. Thundering basses, scorching treble, and immense musicality are always on tap.

Customizable control, tailored to suit your sound
Compared to the last-gen Monitor model, Monitor III A.N.C. headphones offer an extended listening lifespan, adding a whopping 40 more hours to your in-between-charges performance. Marshall spared no effort to ensure you’re totally in the driver’s seat for every second of sound. The right earcup features two dynamic controls: a multidirectional knob and a customizable M button. Use the knob to navigate everything from Bluetooth connectivity and playback configurations to volume levels and incoming phone calls. Tap into your personalized M-button magic to activate your smartphone’s voice assistant, adjust EQ settings, traverse your Spotify playlists, and access many other capabilities that suit your sound.


State-of-the-art sonics
Dynamic 32-millimeter drivers pump out crystalline sonics for (literally) days of listening, but these formidable foundations are only the beginning of the Marshall Monitor magic. In addition to the versatility afforded by the noise-canceling and Transparency capabilities, the one-two punch of Adaptive and Dynamic Loudness keeps your hi-fi haymakers hitting with reliability and clarity. On the Adaptive side, the Monitor III A.N.C.s constantly make micro- and macro-level tweaks, accounting for fluctuating noise levels around you and keeping your playback consistent at any volume. Meanwhile, the Dynamic Loudness actively refines the lows, mids, and highs of your EQ curve, optimizing your enjoyment throughout the day. Adding to this gargantuan garrison of tone-honing tech is Marshall’s state-of-the-art Soundstage spatial audio technology, supplying unbridled immersion that’s on par with being in the studio, right next to your favorite artist.
Mobility-minded design meets uncompromising quality
Thanks to the free-to-download Marshall app, on-the-fly adjustments and deep tweaks to your tones are never more than a tap away, conveniently and intuitively navigated from your smartphone. When you need to step away, the massive 30-foot range of the Monitor III A.N.C.'s Bluetooth 5.3 wireless range has you covered. The included USB Type-C to 3.5-millimeter cable guarantees full-fidelity performance whenever you need to plug in. Speaking of which, the built-in Quick Charging capabilities provide 12 hours of listening in just 15 minutes. When you're ready to pack it up, the included carrying case provides solid, stylish security, supplementing the headphones' foldable design and making transportation easy. We’d be remiss not to mention that Marshall built the Monitor III A.N.C. headphones with an environmentally conscious approach. Heeding Marshall’s heritage and dedication to sustainability, these headphones were crafted with a vegan leather headband, DMF-free hardcase materials, and 66% GRS-certified post-consumer recycled plastic. With high-quality construction and rich, musical listening in mind, the Marshall Monitor III A.N.C. headphones are built to be enjoyed for the long haul.
