أيهما يجب أن تشتري؟
The ULT Wear 2 is the clear pick on raw spec strength, leading by 9.5 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
The HD 660S2 doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.
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 driver size, weight, active noise cancellation, among others.
Both ship with comparable spatial audio, water resistance, so those specs don't separate the two — focus on the differences below.
Bottom line: the ULT Wear 2 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
