Headset recommendations

[Kergan]

So I've decided my current headset is a piece of shit so I'm taking advantage of holiday deals to buy a new set of cans.

1. Sound quality is #1 to me
2. I would like to be able to use them with my iPad or iPhone in addition to PC
3. No preference wired vs wireless
4. Price not a factor, but I don't want to pay an extra $100 for a very marginal upgrade
5. Should look decent, I might bring them into work on occasion or use on the go, in airports, etc.
6. It doesn't need to be a "gaming" headset either. A really nice pair of headphones with a mic option would be fine.
