Buy the Monitor III ANC if battery life and attitude matter: Marshall rates it for 70 hours with ANC on and 100 hours off, the sound is big and punchy, the comfort is good and the noise canceling holds its own. Spatial audio and LE Audio support add flexibility. Skip it if you want hi-res codecs or a cool fit on hot days, because there's no aptX or LDAC and the cups get warm.
