Which should you buy?
The HD 800 S edges ahead on the Mars Score (67.1 vs 73.6), but the 6.5-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 active noise cancellation, multipoint, battery life.
Pick the HD 800 S if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are driver size, weight.
Both ship with comparable spatial audio, ldac, water resistance, so those specs don't separate the two — focus on the differences below.
Bottom line: the HD 800 S is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
