I have a pair of JLab Air Icon headphones I was able to connect to the Zenfone 6 before the Android 10 updates but since the Q update, I haven't been able to connect to them at all. Sometimes it shows invalid pin, other times it just tries to connect for like 5 minutes but then won't. I have other devices connected through Bluetooth, including a pair of Skullcandy Push headphones, car stereo, and a Steam Controller.
