Performance

1. Sound Quality: Marshall’s Signature Audio

The defining feature of any Marshall product is sound quality, and the Monitor III ANC headphones don’t disappoint. Equipped with Dynamic Loudness, the headphones automatically adjust the treble, mids, and bass to ensure a balanced sound across all volume levels.

The newly introduced Soundstage Spatial Audio adds depth to the listening experience by creating a wider soundstage, moving the music beyond your head to give a more immersive feel. This feature particularly shines in high-quality genres such as classical, jazz, and well-mixed pop, though it might feel less noticeable in heavily compressed audio or bass-heavy tracks.

2. Active Noise Cancellation (ANC) and Transparency Mode

The Monitor III ANC features three levels of adjustable noise cancellation, allowing users to personalize how much noise they want to block out. Whether you’re on a noisy plane or in a busy café, the ANC does an excellent job of muting background noise, letting you focus on your music or calls.

For times when you need to stay aware of your surroundings, the Transparency Mode is a useful addition, although it could be slightly more refined in terms of clarity and amplification of ambient sound.

3. Battery Life: Class-Leading Longevity

With 70 hours of playtime with ANC activated and 100 hours without ANC, the battery life of the Monitor III ANC is an absolute powerhouse. Even for heavy users, these headphones will last several days on a single charge, making them perfect for long-haul travel or extended commutes.

Charging is also efficient, with the headphones providing several hours of playback after a quick top-up via USB-C.

4. Design and Build Quality

The rugged design reflects Marshall’s signature aesthetic—elevating both style and functionality. The foldable ear cups allow for easy storage in the included hard travel case, while the soft ear cushions ensure comfort during extended listening sessions without causing pressure or discomfort.

Thanks to their lightweight build, these headphones remain comfortable even during long periods of use, a feature praised by many users.

5. Controls: Physical Buttons for Easy Navigation

Marshall emphasizes usability with intuitive physical button controls. Users have highlighted how easy it is to adjust volume, skip tracks, or toggle noise cancellation without needing to pull out their devices. While touch controls are becoming the norm in modern headphones, some users still prefer the precision and tactility of physical buttons.

6. Connectivity: Bluetooth and Wired Options

The Monitor III ANC supports Bluetooth connectivity, allowing you to enjoy lossless audio through wireless streaming. For those who want the flexibility of wired use, the traditional 3.5 mm audio jack provides this option.

However, the absence of Bluetooth Multipoint, which enables seamless switching between devices, is a notable drawback for users juggling multiple devices throughout the day.
