HammerHead True Wireless, which ones to get

So my current Hammerhead true wireless's have almost completely gone silent in one earphone (probably due to dropping it) so i'm now looking for a new pair. However i'm torn between the Hammerhead True Wireless (2021) or the Hammerhead True Wireless X. The only differences im seeing are the headphone impedance, i don't know if lower is better, the input power, which im guessing is for battery life. The drivers 10mm vs 13mm, how much of a difference is there in sound? And of course Chroma Just need help deciding or understanding the differences between the two
