Searching for a comfortable headset with a good mic for GMing

Budget and location - Budget should ideally be around 100€, could go to 150€ in a stretch. I am in Germany, so I guess the popular recommendation (PC38X) won't be possible.

Source/Amp - Desktop sound, USB or AUX would be fine.

How the gear will be used - Mostly for GMing, only for talking. So it should have a clear mic and should be comfortable to wear for multiple hours.

Preferred tonal balance - As long as it can handle speech, it's fine for me.

Past gear experience - I have currently two set-ups available: Use a HD599 for sound and a Yeti Nano Blue for a mic. Problem is, I am not happy with the Yeti Nano when I'm not speaking directly into it and I don't want to have to speak directly into it when GMing. Other option is an old HyperX that is just not nice to wear for a long timedue to temperature and pressure around the ears.

Anything else? - As I said, I already have a HD599. Maybe there is a separate microphone that could handle my moving better than the Yeti?
