I bought it today, not much of a bargain compared to Apple usb-c to 3.5mm which is $15 but I thought people should know what they are buying
hooked up to my windows 10 pc I can see that audio output is 16 bit 48Khz (DVD Quality) non-changable and can record 1 channel, 16 bit, 48000 Hz (DVD Quality) also non-changable
my pc describes this as "CBHT audio" idk what that means
this kind of information should be written at the back of all usb-c audio adapters but not even apple has any info on their package
also from using it, when using a standard TRS plug iTunes goes crazy playing and pausing non-stop but using a TRRS plug from a headphone with mic it works fine, I might buy an adapter to use it with standard TRS plug
this post is just a FYI
Can get one for literally $3.99 on eBay, and no reason I'd trust this one any more than that one.
