That is completely individual and i can't think what would be large or small head. Well, perhaps when comparing child vs adult.
In any event;
What would fill the criteria is the very same headset i have;
Corsair Void Pro RGB USB,
specs:

Or the newer version: Corsair Void RGB Elite USB,

However, do note that no-one can answer you which headset to go for, since people hear sounds differently and value different frequencies. E.g, i, personally, value deep bass above everything else and care little about mid-range and high-range. While i also require Dolby 7.1 surround sound within my headset.
Your best option is to read reviews, whereby headsets have been reviewed by the same person. This, at least, would tell you sound quality differences between the two, but that's about it. How headset sits on the head, how well covered ears are, how clear the sound is etc <- all that is individual preference and can't be taken into account when choosing a headset.
All peripherals and PC cases, that have to do with individual taste and feel, can't be suggested accurately by other people, since other people suggest hardware based on their own, personal requirements, which, often doesn't align or even match yours/theirs.

Like i said above, i'm using Corsair Void Pro RGB USB headset (
specs) and i like it a lot. It has good low-range and is also very comfortable to wear.
I gave my headset to my missus to test and to her, my headset felt too heavy on the head/neck, while to me, this isn't an issue. Void Pro RGB USB also doesn't have much clamping force and if you look up or down, headset will fall off. Some look it as negative, but there's also a flip side. Lower clamping force means that headset doesn't pressure temporal lobes (area around ears) and won't cause headache due to the pressure. Some people are more sensitive to the clamping force than others. To me, that means i can wear the headset for extended periods of time (which i do, several hours a day), without feeling uncomfortable.
Corsair Void Pro RGB USB does have quite a bit of plastic in it's construction, but since i take good care of my hardware and won't rough handle them, i have 0 issues of it being made partly out of plastic.
