If I can't get the audio files to my PC or Mac this thing becomes useless. After following the sub-par instructions to connect to either my macbook or windows 10 machine, the device is not detected on either, using multiple different micro usb cables. The OTG cable setup included makes no sense for connecting this to a mac/pc. I've already submitted for a refund within minutes of receiving the device as I can tell it doesn't work as advertised - or this is a defective unit. Either way its a little too pricey to hold on too for a 5000mah power bank alone.
