Seller and package OK, item sent cuickly, it works normally. But I must say: the DAC is not good, it can't drive higher impedance headphones, my AKG K240, no volume, only distorsion., it's simple low mw capacity, or i don't know... Android and win PC also! Connected 32ohms Samson sr850 a little higher volume, but quality as all is not better ad $10 DACs... I not recommend this DAC. I will buy it in my country on used online market for any users.
