What equipment will be powering these cans? Will you be using an amp?
What is the format of your music and other sounds you will putting into these cans?
Describe the sound signature that you are seeking?
Do you plan to use them outside your home? If so, in what way & with what equipment?
At the current time, I have no amp but would be open to suggestions for a decent amp or DAC (in that case my budget would be about $250 total. I'll be using my computer, never leaving the house.
Format is generally lossless, but some mp3. Music only.
As far as sound signature, As long as they aren't too bass heavy I'll be happy.
