The following shows you a low-cost fix to reattach the earpiece material to the base your Plantronics RIG Headset if has detached from the base of the unit through normal use.
Note/Disclaimer: This fix will void your headset warranty. Don’t blame me if my steps don’t fix your issue, make things worse, prevent you from getting warranty support afterward, or need to replace your headset. Follow safety instructions and use common sense.
Despite taking care of my headset for almost a year, recently the fabric that hold the foam in place around one side of my headset gave way, preventing me from comfortably wearing the headset.
