Definitely not alone. I have a USB A headset. I have a new macbook pro with USB(C/thunderf*ck?) adapter that lets me use this headset on my mac. No biggy.

Anyway one day I was like, huh, I bet this won't work, but I plugged my Mac adapter into my Oneplus phone, with the USB A headset attached. The phone actually detected the headset, including the volume up/down button built in.

So yes, USB-C simplified my life.
