Blame the designers for making gear with only Hyurs in mind, and not making different versions for other races. Looking back at gear they've progressively been getting lazier with it, as some Heavensward gear, helmets the ear pockets look like they are just a pair of spikes glued on top rather than actually being designed for them...
Late HW and SB, things started just removing the ears.
ShB onwards they're barely even trying.
Ultimately, I rather they just hide the ears rather than half-assedly try to make the gear work, because clearly they're not gonna make the extra effort to actually make multiple versions of the gear.
