Audio Technica ATH-M50X M50 Ricambio Cerniera Fix Riparazione - Non sono necessari attrezzi

A well known fault with the Audio Technica headphones are the hinges that keep your headphones fitting nice and tight. No tools required. This will not affect folding and rotating! This nifty little bracket will give your headphones a new lease of life and make them feel like new again.
