You can mod an existing cable, or get a cable adapter (search for "OTG adapter" on Amazon - just be aware that sometimes they aren't wired correctly either so buy two from different sellers), or buy a finished cable. I am not sure if Ibasso sells the short micro OTG to USB-B that comes with one of their DAC-HPamps though. Forza Audio Works sells longer cables for around $80 - I'm waiting to see if AudioQuest will make a Forest-series OTG cable that retails for less than half that, otherwise I can live with the added bulk of the adapter since I only use my Android with a separate DAC at home)
