Calling some headphones "gaming" just means the company is trying to charge more, or exploit a niche.
The best headphones for you are -
- Ones that you can afford.
- Ones that are comfortable to wear for the duration you need/want to wear them.
- Ones that sound decent to your ears.
Here are some headphones that I own and (mostly) like.
Sony MDR-V6 sounds really great to me for music, but aren't so great for long-term comfort (hot ears, bulky).
Razor Moray earbuds are my go-to for portable use (MP3 player) and taking on trips. They are really sensitive so they pick up any hiss that you think your computer sound card doesn't put out, but they are super comfortable to me (and I've tried probably a half dozen different in-ear earbuds) and they sound decent to me. I like the unequal length cord (wearing over one shoulder) but it could be a few inches longer so that I can carry my MP3 player in my pants pocket easier. The cord is also rubberized, which makes them stick to anything that touches them which is irritating. Since they are in-ear (with different sized cups for personal fit) they do attenuate some outside sound. I like this aspect and I will wear them in planes even if I don't have my MP3 player plugged in. I find that I feel less tired after a long plane trip if I wasn't subjected to several hours of droning sound.
Steelseries Siberia (orignial, not v2) are my daily gaming wear headphones. I like them because they are very lightweight and super comfortable to wear for several hours. No sweaty ears, because they are somewhat open air, have vents in the cup and the pad cover is some velour type material, not the typical vinyl/pleather. The cord is so short that it is almost useless, though they do come with an extension that makes the cord too long. I've heard a lot of reports of these breaking in various ways, but I'm really careful with mine and have used them for over a year (knock on wood).
I use a cheap hand held microphone in a microphone stand for voice chat. Sounds a bit better than the typical mic-on-a-stick.
