Beyerdynamic - Aventho 300 vs Bang & Olufsen - Beoplay HX

The Aventho 300 edges ahead on the Mars Score (72.6 vs 68.3), but the 4.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.

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, weight, ldac.

The Beoplay HX 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.
