I use a Sony Z3 Compact with Pocket Casts. If I’m working I’ll connect the phone via. Bluetooth to my docked Fedora laptop for the audio (easiest Linux bluetooth setup I’ve ever done too!). If I’m flying I have a Bose QC25 headset to listen on. At hotels I have a Chromecast to listen though the hotel’s TV.
I don’t really drive very often any more but I can bluetooth to the car if I need to.
