Volume loss in my IEMs(KZ EDC PRO)
I Bought my pair of KZ EDC PRO months ago from Amazon and they have been working great accept recently I noticed that their volume felt a bit too low compared it to one of my friends pair of some 400₹ earbuds and the difference was drastic mine is like 30-40% of the volume to his on the same device and settings can't determine whether this is a cable issue or a driver issue any tips?
