What's the purpose of this dongle??

iPod Shuffle charger?

It's a digital to analog audio convertor for USB it looks like.

If it also does analog to digital this might make sense as a way to verify sound output.

I.e. debug a program that uses the headphone jack, or workaround software loopback device limitations.

Given the white body, it could be a USB cable for one of the early iPod shuffles?

It is exactly that. Really simple cable too. All of the apple 3.5mms are 4 pole (I think for play/pause, track seek capability) so it’s just a USB connector in a different form factor.

It isnt Left/Right/Ground/Mic? Ill dont know how the skip/pause stuff is done, will do some more research

Signalling done on mic wire.

They exist, it seems. Actually, there might be a niche use case for audio editing or getting around some kind of software limitation. I have probably done worse in my day.

Sound output from USB to a device with an aux port, or sound input from a camera or microphone or other device with a 3.5 mm output (headphone jack)

It’s incredibly short though.
