Beyerdynamic - Aventho 300 vs Sony - ULT Wear 2

These two are nearly even on the Mars Score (72.6 vs 70.9). 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 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.

Pick the ULT Wear 2 if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight.

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.
