Audio-Technica - ATH-R70xa vs Bose - QuietComfort Ultra Headphones

The ATH-R70xa 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 ATH-R70xa if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, driver size.

Pick the QuietComfort Ultra Headphones if audio quality and feature breadth (ANC, codecs, multipoint) are the lead criteria for your purchase. Its strongest claims are active noise cancellation, spatial audio, multipoint, among others.

Both ship with comparable ldac, water resistance, 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.
