Fairphone

I live in the US and just bought a pair of Fairbuds XL which I like so far but I'm a bit annoyed they don't have a 3.5mm jack and don't come with the USB-C to 3.5mm cord either. They don't seem to stock it on their Amazon store and since I'm in the US I can't order from their website either.

What other options do I have? Can I used a generic USB-C to 3.5mm dongle to use them wired? Or do I need Apple's $40 USB-C to 3.5mm cable?
