I've been using the standard white usb Apple cable, but this is perfect for performance because it is low-profile (being black/grey) and the braiding feels very high quality.
It's so nice to not worry about ever running out of power for your iPad set lists and transcriptions during a gig. I keep this cable always with my pedal board so I know there's always going to power available.The black cable blends into the mic stand and doesn't draw attention to itself. One less thing to worry about on a gig. Very well thought out accessory.
Great quality, snug fit, flexible, works.
