All good opinions in this thread. I would just like to add...
As a hobbyist, I mostly buy "midrange" (=midpriced) headsets/headphones, mics, etc. Yes, I'm talking in plural, because from my experience, sound quality is only half of the equation: the second half is, how comfortable some headset is on MY head. That is, before deciding, one really need to try them on head.
The one I still use most of the time, is Sennheiser wireless headset (about 170€): sound is good enough for me, but not as good as wired AKG that I also own. Headset mic is not really good (same as on most headsets), but battery life is enormous -which is quite important for wireless headset.
But after about a year, ear cushions/pads literary fell apart and Sennheiser wanted ~30€ for new pair. Now, paying 30€ each year for new pads wasn't an option for me and so I started to look for new headset -where I was ready to pay a bit more, if I find "the right thing".
I tried many headsets (for comfortability).. even 400€ Bose wireless headphones.. and I ended with ~120€ Sony wireless headset. The point being... yes, Bose is high quality, but I don't feel comfortable wearing it for longer period of time! It's the same as with shoes: they either fit or they don't. Means, headset that is perfect for me, is not necessary good for you. It depends on many things: size of outer ear (helix), head shape, is person bald or not, is person wearing eyeglasses, etc.
Btw. how come I still use Sennheiser after buying Sony? I took pads from some cheap headset that I had, and they fit pretty well on Sennheiser (and on my ears).
Just though I share my experience,
