Too much bass in desktop sounds with a headset, but not during recording, only afterwards I recorded some video footages with my voiceover, both with Fraps and OBS. (Also streamed with the latter)


While I was playing everything was fine. (I played with a headset)
When I played the videos on my notebook speaker, they were fine.
But when I played them with my headset on, they had too much bass. But only the desktop sounds. The mic input was fine.


Any ideas?
The fact that is sounds fine on your laptop speakers is probably because they do not reproduce much bass anyway.
To be sure that there is a difference in the recording, and the "live" sound, you could directly compare your recording after doing something like listening to a song on youtube, without changing volume. This allows you to go back and forth. If you're sure there is a difference you could post the example here.
