I have a question about maximum audio output power in micro USB and 3,5mm jack sockets. My problem is that I have large headphones with impedance of 80 ohms, max input power of 100mW which sounds really quiet when plugged to mini jack socket. I wonder if I plug them through micro USB to 3,5mm jack adapter, would they be a bit louder? I have heard that jack output power on s4 is about 4 mW which looks small compared to 100mW of maximum input power on the headphones.
Thanks, Greetings from Poland
