how do i connect bluetooth headphones to xbox series x properly?

does your tv do bluetooth? pair the headphones to the tv and leave the xbox out of it. bit of lag, fine for single player, annoying in shooters.

you can't, at least not directly, and it's not a pairing problem on your end. the series x has no bluetooth audio at all. it only talks to headsets that use microsoft's own xbox wireless protocol (the ones sold as designed for xbox), or ones that come with their own usb dongle for the console. workarounds if you're stuck with bluetooth ones: plug a wired pair into the 3.5mm jack on the bottom of the controller, or buy a bluetooth transmitter that plugs into that jack. some people also join party chat through the xbox app on their phone, but that only carries voice, not game audio.
