Good afternoon, night or day. Community, I have a small speaker SPI 170 from Genius, which has a special cable that I no longer have. The cable was exactly this: It is well known that the micro usb connector has 5 pins, and the 3.5mm plug has 3, I suppose the remaining two are for charging via USB; unfortunately I'm not sure what should go on each connector, so a little ayda could use it, if they could help me to make the connection correctly, I would be grateful. Cordially, Danilo González "a curious technique"
