Question USB C to AUX Adapter not working

[Justanumber9826]

These are my headphones: Sennheiser CX 300 II Precision In-Ear Headphones 1.2 m Cable Length 3.5 mm Jack
This is the usbc-to-aux-adapter i bought so that i can listen to music with my samsung A33 phone:

Music keeps playing over the phone instead of headphones, its just dissapointing.
Why does it not work? Can i fix it?

Would this one work instead?

Does the phone support USB-C audio? If not, no matter which cable you buy, it will not work.

Thanks for the info, didn't consider that. I asumed it would just be compatible using the adapter.
There's not a whole lot of information about this topic on the net.
Where can i find a list, or find out for my particular device if it supports audio over usbc?
