Review on Apple MFi Certified Lightning to USB Camera Adapter: USB 3.0 OTG Data Sync Cable for iPhone/iPad, Supports Card Reader, USB Flash Drive, Mouse, Keyboard, Hubs - Plug and Play by John Munajj

I am using this to hook up my Dragonfly Red DAC. Works great and no iPhone errors about unsupported devices. My only caveat here is whether the cable is the same quality as Apple's official cable, which isn't as good either. The ankle chain makes the cords better, but they cost more than these. Let's see how long this lasts. I never unplug it from Dragonfly or wired headphones so the cable will last longer.
