I’ve aquired recently a used pair of Plantronics BackBeat PRO, and got the next issue - the right ear is not working at all, ar there any guides of disassembling the headphones and/or some advice related to reparing appeared issue?
Typically, when you pull the ear cup padding back, you will find 3 or 4 screws that hold the driver plate to the cup. Another setup is a series of slots and tabs. There, all you need to do is use a small flat tip screwdriver to disengage the tab and separate the plate from the cup
