Beyerdynamic - DT 1990 Pro MK II vs Bose - QuietComfort Headphones

The DT 1990 Pro MK II edges ahead on the Mars Score (66.2 vs 62.9), but the 3.3-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the DT 1990 Pro MK II if you care most about driver size. The biggest gaps in its favor are driver size.

Pick the QuietComfort Headphones if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight, active noise cancellation, multipoint, among others.

Both ship with comparable spatial audio, ldac, water resistance, so those specs do not 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 says both are well-rounded; the differences are about trade-offs, not quality.
