Fiio UBTR holder for AKG K271headphones (removable wireless conversion)

A flexible insert that lets you put a Fiio UBTR Bloetooth receiver on the AKG K271 headphones so that it doesn't rattle. You will also need a 3.5mm headphone jack, a female mini XLR connector and a short headphone cable to connect it without having a dangling cable. You probably want both plugs to be angled, because it will look less like crap then. I only had straight ones. And yes, I do wear that in public sometimes.
