Hello mate.
250$ are a lot of money to be wasted on a gaming headset alone. Gaming headsets kinda suck on everything, except gaming. I tried a lot of gaming headsets (like Logitech G430) but they were lacking seriously when i wanted to listen to my music.
The way i went, after a lot of searching, (money werent a problem) was Kingston's Hyper X Clouds (a headset that doesn't suck) combined with a soundblaster sound card. Hell, i saw a huge difference everywhere, both in music and gaming! This headset is veeery good on both worlds and the card boosted that to the limit. They cost around 90$ and the sound card took me another 80$.
You can go with Cloud II also, around 100-110$, they have a built-in USB 7.1 surround sound card, so you can use them with PC and XBOX. Excellent sound and build quality in both headsets, and the microphone is very decent. You can see what im talking about on many reviews on the Internet.
The only thing i can recommend above this, is a combo of audiophile grade headphones (like 150$+) combined with a standalone microphone, but is less practical and you arent gonna notice a big difference over my previous suggestions.
