Well, I did come across a revelation I believe. I found an aux cable from amazon that on the other end has a USB type C plug! Though it doesn't sound as good as a regular aux cable, it does sound much better than using that stupid dongle. Whatever, I'll take it. I wish these were more common though so I could find different choices.
Now onto the phones... Odd how on my Oneplus 8, it sounds good, but on my most recent device, which I am really liking and will be my device from now on, the Note 10 Plus, it sounds even better. Pretty close to regular 3.5mm aux cable quality.
Note 10 Plus has everything I need on it except the headphone jack obviously. My only other gripe is the stupid ultrasonic fingerprint reader. I wish it wasn't there so I could get a decent case with a built in screen protector. I think I will be selling my OP8.
