Marshall Major V MDAQS
Multi-Dimensional Audio Quality Scores, Scale 1 - 5
Virtual mean opinion scores (MOS) on a 1–5 scale, modeled from the measured response by HEAD acoustics’ MDAQS (Multi-Dimensional Audio Quality Score) model. Higher is better across timbre, distortion, and immersiveness — add other models to see where this one lands.
The verdict
The Marshall Major V headphones are a fun, rock-and-roll-inspired option for casual listeners who don't need ANC. With plush ear pads, long battery life, and wireless and wired listening options, the Major V headphones still have plenty to offer. However, its stock sound needs some taming from its companion app EQ for the best possible listening experience.
✓Liked: Companion app w/EQ options, Wired listening, Multipoint, Lightweight
✕Could be better: Treble heavy stock sound, No carrying case, No ANC
