What cable/s do you have on? I use a meenova lightning-to-micro USB cable which worked fine before on an iPhone 6s+.
I'd like to know if the official Apple CCK (USB3) would fix the issue or not; I'm confused now after reading statements that say both yes it will and no it won't.
I am using the original usb cable that came with, and the apple camera connector usb. Works nice. Was most supprised that the iPad Pro 10,5” and the mojo sound so alike. Maybe a 5% difference in mojo being better, softens and darkens the sound a tiny little bit.
