Question / Help I can't hear Sound myself when OBS is running

[Lost]

OBS was always worked ... now I have bought new headphones and then I had no ingame and audio sound. I was able to fix that quickly by setting everything to default (desktop and audio sound). That worked and in the recordings I could hear everything but as soon as OBS was running I couldn't hear anything myself (even without recording). As soon as I close OBS I hear everything again. Plz help,
Thanks Tom

Sounds like the new headset is a bluetooth headset. Bluetooth headsets have separate outputs based on whether the microphone is or isn't in use, and this "phone" mode is super low quality. In OBS, you'll need to set your microphone to something that isn't on the headset.
