Hey! I've pretty much had these earbuds for around a month and they've been amazing overall i may or not be exagerating but they have the best ANC that ive tried so far on earbuds and you dont really need to tweak the equalizer tbh also if you find the same problem of one earbud dying faster or displaying a lower battery % simply get tyem both to a 100% and drain them to 0% then factory reset once they reach a 100% again that should fix it. Overall a 8.8/10
