I usually avoid headsets and would rather have my regular headphones (e.g. in-ears for me) combined with whatever mic I have at my disposal since I have a couple of them. Headset mics are usually crap, a 5 euro clip-on mic will probably sound better than most (gaming) headset mics.
Just thought I'd share this because we don't all have to own crappy/uncomfortable headsets with crappy mics :)
@Gina Depending on your budget and how portable you need it to be, you could look at some entry-level streaming/podcasting mics and couple it with whichever headphones feel most comfortable to you. The two below both come with their own stands while taking up minimal desk-space.
