I really like my old Stax Electrostatic headphones and their amp to drive them. I'll admit I am biased toward them, but it wouldn't hurt you to start your listening / shopping experience with them and move on from there.
Do check out headphone systems at twice your budget so you know what you are missing out, if anything. At least, if you do discover the difference, you can make an honest judgement.
Be careful though, it is very common to do permanent hearing damage with headphones as pumping too much SPL in the tiny ear canal is easy to do.
For open back headphones, in general if you can't carry on a conversation with someone in a normal voice at 3 to 4 feet, the phone volume is too loud. Turn it down!
