i tried cleaning the grill with a needle but i think i should use a tooth brush,,,,i will try it today only as sending them back will cost me 18$...........and i don't want them to be returned as it is with lmue refusing to acknowledge any imbalance.
but diff is there,,,i have compared it with my other cans
Yes, use a toothbrush and some alcohol (in Australia it is called methylated spirits). You not only want to clean the grill but dissolve any wax build up or grime. (just dip the toothbrush in a cap of alcohol to wet it)
I'm guessing it is the problem especially if it just went like this from a normally working earphone.
