Which should you buy?
The MW75 edges ahead on the Mars Score (67.1 vs 62.9), but the 4.2-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the MW75 if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are battery life, driver size.
Pick the QuietComfort SC if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight.
