Total scrap, unusable because not functional!

Waste of money and unfortunately I can not return times because of the value of goods is so low that the return costs would cost more than the adapter itself that. The adapter does not work and I tested it with three (!) Different headphones to a total of five (! ) various audio sources. Once you use this adapter is only noise and scratching from the connected headphones. Either I have received a defective adapter, or the part is really just scrap!
