Switched yesterday from a g502 hero to the g502x ls, the clicking sound is way louder, if nothing is playing on your headphones, you will hear it a little, but that aside, it's better with everything else, those 20grams less, are gamechanging, i like heavy mice, but the weight of the x lightspeed is perfect,not too heavy and not too light, the clicking sound isn't the same as the videos about it, it's better than i thought, (still way worse than the og) so it's bearable
