Overall external noise reduction (ANC on): 83% · ANC low/mid-frequency attenuation: ~20 dB · MDAQS Timbre score (1-5): 4.8 · MDAQS Overall score (1-5): 4.4
The default tuning of the Marshall Monitor III ANC will please most casual listeners, given the exceptional Timbre score of 4.8 on a scale from 1-5.
All told, this means the headphones reduce the loudness of external noise by an average of 83%.
Android users will be disappointed by the absence of higher-quality Bluetooth codecs such as aptX or LDAC.
Podcasts, film, TV, YouTube videos, you name it – the Marshall III ANC headphones are putting on a good show with well balanced sound.
My only minor gripe is the bass could be a little turned up, especially on bass boost.
With noise canceling turned on, the Monitor III will last you a grand total of 70 hours.
The combination of the two, when they work with the headband, makes them supremely comfortable, moreso than the previous generation.
There is a slight creak when the earcups are squeezed with even the lightest touch
