Comfort
Wearing the Marshall Monitor III ANC feels natural. The grip is secure without being tight, and the vegan leather pads are soft. Long sessions get slightly warm, but less than expected.

Sound Quality
This is the highlight of the Marshall Monitor III ANC review. Balanced sound, dynamic bass, and clear highs make it versatile across genres. Rock tracks have energy, while Bach’s violin sonatas sound delicate and precise. The Soundstage mode creates an immersive spatial experience—especially with Apple TV. Wired vs. wireless showed no noticeable differences.
