I sometimes plug in a wrong hole with my computer speaker's jack by mistake. I meant to plug it into my PB's head phone jack for external speakers; but, I miss my aim and put it into InLine port instead (and plug it out quickly for the head phone port). Is it bad for PB by putting in the wrong jack to In Line port? Usually PC's head phone port is color coded in green; but, PB does not color-code its head phone jack.
