My headphones broke last week (I'm suspecting frayed enamel wiring between the ANC power and signal in one ear), a friend ordered me a new set as a gift, and as a bonus, the airplane adapter that came with it is the precise thing I need to replace a broken jack on a lapel mic my old roommates left behind so I can use it as a way to record and maybe amplify my classical guitar for experimental purposes? Hmmm
