Beyerdynamic - Aventho 300 vs Sennheiser - Momentum 5 Wireless

These two are nearly even on the Mars Score (72.6 vs 73.9). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the Aventho 300 if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight.

Pick the Momentum 5 Wireless if you care most about driver size. Its strongest claims are driver size.

Both ship with comparable battery life, 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.
