I just got my headphones ... I do not know if I 'am happy because it is missing a piece in the package !!!!! since I do not know where ... I ask very bored !!!!! As you see I am a customer for a long time and this is the first time I'm in trouble ..... Indeed the goal of the helmet was to amplify the sound of the TV without disturbing others ... but I lack precisely the RCA stereo adapter 3.5mm ...... What should I do ???? ??
