I had a brief foray into using a set of Bluetooth headphones for PC gaming. It was “brief” because the delay was enough that it got me killed in games regularly enough that it was just intolerable.
Yeah, for gaming you need headphones that use some proprietary protocol, unfortunately. BT just doesn't work well.
It's not as noticeable for people who never talked on a real landline phone (i.e. not VoIP) because everything else has noticeable and often non-constant latency.
