## What reviewers say

Across three hands-on reviews (SoundGuys lab-tested; TechRadar and Tom's Guide qualitative), the Marshall Monitor III ANC earn a solid recommendation for class-leading battery life (70h ANC on / 100h off), lightweight comfort, and fun, well-balanced sound. SoundGuys and Tom's Guide both note the ANC trails Sony and Bose class leaders, while TechRadar's reservations center on price, looks, and the missing aux port. (Based on 3 reviews, 1 lab-tested, 2024-09-24–2025-02-13.)

Praised: Class-leading battery life (70h ANC on, 100h off); Lightweight, supremely comfortable fit; Fun, well-balanced sound quality; Rugged amp-inspired design with compact hard case; Tactile physical control knob beats touch controls.
Flagged: ANC weaker than Sony/Bose class leaders; Soundstage/spatial mode underwhelming (adds reverb, not real width); No dedicated 3.5mm aux port; High price relative to features; No hi-res Bluetooth codecs (aptX/LDAC); Slight build creak and on-head twisting from folding hinges.
Disagreement: Value splits the panel: SoundGuys wishes the price weren't so high and TechRadar calls them 'not cheap', while Tom's Guide argues the Monitor III undercuts Sony, Bose and the AirPods Max and is an excellent-value buy, especially in the UK.
