Which should you buy?
The FH19 edges ahead on the Mars Score (72.9 vs 65.4), but the 7.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the FH19 if you care most about impedance and sensitivity. The biggest gaps in its favor are impedance, sensitivity, driver count.
The ZAR similarly doesn't carry a headline advantage on the popular specs — look at the full table for category-specific deltas.
Both ship with comparable detachable cable, so those specs don't separate the two — focus on the differences below.
