The iFi On-The-Go (OTG) cable comes in two versions: USB C and micro male USB. Both are constructed from pure OFHC continuous cast copper, which conducts clean sound between your Android and DAC. The exterior boasts a braided cable and ceramic finish. It is ideal for Android phones to extract the digital signal to feed a DAC. The USB C is USB 3.0 standard and can be used with Samsung Windows PC laptops and Apple Macbooks with USB C ports. Plug directly into your digital to analog converter or use it to convert USB C to USB A. The USB A connector is designed to connect directly to any portable DACs with a male type A in the iFi line including the micro iDSD Black Label the nano iDSD Black Label and the xDSD, and provides a much more mechanically reliable connection. Connect between your devices and enjoy the music. Note: With some Android devices you must ensure audio over USB is enabled or consult your phone’s manufacturer to ensure your Android phone is capable of USB host mode, so that the OTG can extract the digital signal.
