I recently got my Sony WH-1000XM4 headphones, and once they’re charged, I’m planning to use them mainly over Bluetooth rather than just the wired option. From what I understand, they should pair pretty easily with my Amazon Fire TV Stick 4K Max since that device supports Bluetooth audio, so that’s probably the simplest setup. My Sony XBR-65X850E TV might also work because some Sony TVs include Bluetooth headphone support, but I may need to check the settings to confirm it can output audio to headphones. I’m less confident about my Roku TV in the bedroom, since many Roku TVs don’t natively support Bluetooth headphones, so I might have to use the Roku mobile app with private listening instead. As for my receivers, I’m pretty sure their Bluetooth is input-only, so they likely won’t send audio out to the headphones, which means they’re probably not an option for this.
