I bought a ugreen one from Amazon that had a y-split so it could charge and play aux out at the same time.
It had a crackle ☹️ (regardless of if it was charging)
But my cheap nobrand straight USBC to aux from Amazon I bought ages ago has been great.
I think it’s a toss up unless you’re going with a name brand converter (apple as another said, agree there - price vs performance will always be good) or a more powerful DAC like a Fiio.
I think so, it doesn’t look like any device from here: https://en.m.wikipedia.org/wiki/Palm_(PDA).
The logo is from the first palms, but it’s way too curvy
