Question Any good Headsets w/mic for big head and ears?

[Raktus]

I use my headset about 10 hours a day for audio editing and recording purposes. So I need something that is comfortable and sounds alright. I've been using a Sennheiser GSP 600 for years now and was loving it. Recently, the ear pads have begun to rapidly fall apart and I thought I could just replace them. I got about three different sets of replacements, all fit tight around the ear and caused things to sound weird, especially my own voice when I tried to talk when wearing them... not a problem I had with the old pads. I figure what might be happening is that the new ones are smaller and tighter and it's causing some sort of effect that the looser old ones didn't have... so maybe I should try a larger headset with larger ear space. Comfort and sound quality would be the chief concern, with micrphone quality second... but still important.
I'd like to avoid running the gambit of buying headsets, trying them out and returning them if I could just find some people with experience and suggestions. 🙂
