Between the Major V and HD 660S2, the Major V comes out ahead in weight and driver size, while the HD 660S2 wins on several specs. Overall, the Major V scores 79.3 and the HD 660S2 scores 61.4 on our Mars Score.
Which should you buy?
The Major V is the clear pick on raw spec strength, leading by 17.9 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.
Pick the Major V 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, multipoint, among others.
The HD 660S2 similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
Both ship with comparable active noise cancellation, spatial audio, ldac, so those specs don't separate the two — focus on the differences below.
Bottom line: the Major V is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
