I have a Xiaomi MIA2 phone and a RHA MA750 Wireless headset. The bluetoothconnection works perfect with spotify, facebookcalls and all other different mediaplatforms, but when in a call the person I call or the person who calls me hear nothing. I hear everything. I have tried a whole lot of options but I havent come up with a solution as of yet so Im begging on my knees that one of u or more than one of u can come up with a solution or more solutions so this problem will be solved asap
