1st. I think you should add a way to see the cases battery percentage.
Also these a are personal my favorite earbuds I've ever used all the features are really good, there one of the only eadbuds soo far that fit my ear they remind me of the apple airpod pros.
2nd. You should add a way to change the sound and bass of the earbuds with like a pro mode or something, for people like me that like to mess with everything, they do have different sound profiles that are really nice but you really need to add a way for people like me that want to customize it are own way.
For One UI5, you need to add way to customize colors your own way not just to match your background but to pick the color you want everything to be.
I don't have the buds 2 pro, but my Beans have a dynamic popup whenever I connect it that shows the case battery. There should also be two homescreen widgets, one that controls a few features and one that shows battery levels for the buds and case
Edit: also there's an equalizer in settings> sounds and vibrations> sound quality and effects, you should be able to set up a Bixby routine to enable or disable equalizer settings when connected to the buds.
