Can I connect UP4 with iPhone 6s Plus by using Lighting cable to USB C in order to get better quality out from iPhone 6s+?
I try to do it but I have no sound coming out from the headphone. Is it the problem from the cable or it's just not supposed to be connected by cable?
Is it any possible way to get a better quality of sound than AAC from iPhone 6s+ and UP4?
Thanks.
In short, it is both because the cable doesn't work and because UP4 is picky on how it can work as a USB DAC with smartphone.
