Brother, I don't want to use Bluetooth headphone or any device. I am not comfortable in using them for health reasons. That's why I wanted to know if we have earbuds (not in-ear) with C Type connector also otherwise, is there any way that we can order each and every required Mobile parts to built a High End phone (Like S20 or P40 Pro or Find X2 etc.) on our own. I am sure it can be done but have no clue where to find them?
if that's the case, I'm afraid the options would be limited to this model of earbuds (as far as i know)
if you want to use your wired earbuds, you can use the usb c dacs, but i don't think it allows phone calls from the earbuds..
custom build phones is a more complex and expensive idea, if that's possible at all..
