Take it from an audio engineer: the big companies we trust are, among others, Beyerdynamic, Ultrasone and AKG. If you want clear sound and isolation isn't an issue, go for open headphones. Closed ones will have stronger bass and isolate better, but sounds less clear. Avoid Beats and Skullcandy at any price. They're overpriced and don't deliver quality that would suit the price, at all. If closed is okay with you, go for the Ultrasone Pro series. The only open headphones they have are the Edition 10s, but those are around 3000-4000€, so pretty much out of your league. :L For open ones, go for Beyerdynamic or AKG. Mind that professional level headphones will have a big audio jack as opposed to the small one you're used to, so you might need an adapter for your equipment. Those break easily and can actually damage your plugs, so make sure to get good ones that won't.
That all said, producing on headphones isn't really to way to go. A good set of studio monitors (you can get a set of Yamaha HS50m or KRK RP5's for around 200€ on ebay) will help you far more when it comes to producing, mixing and mastering, because headphones don't create a proper stereo image (why would take a while to explain), barely ever have a true flat frequency response, and simply are physically not able to recreate the lowend properly. But it's your choice.
