Any reason I can’t cut the headphone input end off a spare GBA SP headphone adapter and direct wire a nice pair of headphones? Or a Bluetooth transmitter? Seems like an easy mod
I was prepared to write it off as personal preference, or OP has a spare set of headphones to play with, but from experience then a lot of the adapters are of dubious quality and it does start to add up to things out the back of your device.you can't use the jack plug of the adapter? Plus your headphone in the jack adapter, then plug it to the gba sp
