I'd recommend either audio technica or perhaps sennheiser if you can catch one on sale. both are reputable and make solid models.
the ATH-M50 is one of my all time favs. very balanced sound, no real downsides for the price.
sennheiser makes the pc 350, which is a great closed ear headset - good condenser mic as well, though a tad above your max budget. it has been dropping in price recently however, so it's worth keeping an eye on, or setting a price alert
