I've been using a Plantronics headset for a while now. It's been pretty rad, though, being wireless, the battery life is starting to get annoying, and I'd like something of a higher quality.
Here's what I'm specifically looking for:
1. Over-the-ear headphones.
2. High-quality sound, large EQ range.
3. Considerable microphone quality.
4. Wireless would be a plus, though, at this point, I don't really care.
5. If wireless, a bomb-ass battery life would be the shit.
sennheiser is a tank brand +1 for the reference, although if your really gonna go to town and back with a headset. i would strongly recomend getting a dedicated sound card to go with them, otherwise your not really getting the best out of your headphones and it would be just plain overkill. my girlfriend has some boss turtle beach headphones and when i plug em in my pc the difference between my headset and her's is minor, but in her machine with her dedicated sound card with the headphone amp there is much much better sound quality, the difference actually becomes distinctive instead of just minor.
Well, my desk is currently occupied by three monitors, a full tower, a 12 inch wacom tablet, mouse and keyboard, and a mixer. I'm kind of tight on room.
