And karma has it that the cable end snapped off and clogged up the plug for the earpiece.

I remember you were saying that you'll be purchasing a new cable.

Does this relate to that?

no I needed a new cable anyway, but the stock cable SNAPPED inside of the earpiece causing it to be jammed.
so I tried a bit to remove the broken piece but it probably needs to be repaired by "United Radio" company.
