hi , i have purchased a razer hammerhead true wireless x for almost a year and right now the battery of the earbuds are draining fast , when i use both earbuds , it up to not even an hour ( more like 45-50 mins ) , for single earbud , left ear last only 30 mins , right ear is 40-45 mins , have tried to use earbuds till it turn off and charged back up to test to see if it will fix the problem and it does not . so what should i do !!!
