Which should you buy?
These two are nearly even on the Mars Score (67.4 vs 67.1). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.
Pick the Px8 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 weight, battery life.
The MW75 similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
Both ship with comparable driver size, active noise cancellation, spatial audio, so those specs don't separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
