Simply disable (or enable) that annoying Voice Mate bloatware.
Quick little tool to disable (or enable, if you're into that sort of tortue) Voice Mate, the terrible bloatware that constantly interrupts music playback among other things when headphones or AUX cords are plugged in.
All this does is disable (freeze) the package, *com.lge.qvoiceplus*, and off you go.
Requires Root.
