I’d like something like JBL Charge, but with USB port that I can connect to PC and speaker would act like external audio device. I’ve only found ones with USB-A to insert pen-drive, which is not the same.

I use headphones exclusively at my PC, but there are times when I’d like to show something to my wife and since I have only one pair of headphones it’s no sound for either me or her. Audio quality is not crucial, so I thought I’d buy bluetooth speaker (which I can use everywhere with my phone) and connect it with one USB cable and it’s done. It would charge when I’m out and I could use it whenever I needed. Well, it seems this idea was wrong since every single one I’ve checked has USB port only for charging. Are there any of these that act as USB audio device?

Does thing like this even exist? If so I’m probably too stupid to pick right keywords to search engine. Thank you everyone!
