I have corded USB type headphones. It’s not a good replacement. The dac is in the connector which makes the portion that sticks out much larger; the port isn’t designed for even mild leverage to be applied to it regularly. Go cycling with your phone in your pocket or even just sit down multiple times with your phone in your pocket while the usbc headphones are plugged in. They will either work their way loose or they will start to break the phone’s port. I’m not even covering how the USB type c spec leaves a lot of room to be interpreted differently by companies, significantly increasing the probability of headphones working for only some phones.
Don’t give up, try a scrapper if the finish sits on top of the vaneer. If the finish soaks into the vaneer and you don’t want to sand through, you can always sand back a bit and then use touch up markers with a fine tip using a close match to the wood grain colors shades to mimic the wood grain pattern overtop of the stained sections. Then reapply finish. Or just live with it as others have said. You are hyper critical of your work but others who admire and don’t know about the “mistakes” likely wouldn’t notice and/or care.
