I think codecs are where I have most of my remaining BT annoyances. AptX is great (but there's also AptX HD, AptX.. is it variable? etc) - and exactly which AptX is supported varies by the Qualcomm chip in your phone and the device you're connecting it to. Or you can go with Sony's LDAC. Works great on my Pixel, once I've turned on "quality" in the Sony App, then turned on the LDAC opton that gives in my bluetooth settings (and optionally can go into the dev menu each time I connect, to adjust the bitrate).

I do like bluetooth - but working out what features will work with which devices is a PITA. It always falls back to something functional, but fallback masks a lot of improvements that could be made. Although maybe that's the right approach. It works, and if you're somebody who likes to fiddle, you can.
