Static, kindly advise us here. 9038D has OTG cable as one option also (Bundle 3). Whats the purpose? Is this for phones without type C ports?
The Y-splitter has two functions:
OTG: if you want to use a DAC that needs OTG (like the PDv2), then you can use this cable to connect it to your Android phone. The 9038S G3 and 9038D have no need for OTG, but the Y-splitter will still work with them of course.
Splitting Power and Data:
If you want to preserve your phone's battery life by providing power to the DAC externally, then you can use this cable to do so.
However, the splitter must be modified slightly to ensure that it is working correctly. Out of the box, the data part of the cable (Type C male to Type A female) still has power lines going through it. That means that even if you plug the power end (Type A male to Type A female) into a powerbank, there's a good chance that your phone will still supply power to the DAC and not the powerbank. In the worst case, your phone can even start charging the powerbank.
To avoid this, you must sever the power wire inside the data cable.
