Budget - We need to know how much you want to spend. If you can, please also indicate whether your budget is a hard limit, or whether it is flexible.

Location - Knowing which country you're (shopping) in is helpful. If your country has a local price comparison site, providing an address to such a site is helpful, and also what your budget is in your local currency - this is because headphone prices can vary a great deal across the world: What is cheap in the US can be expensive in the UK, or something can be cheap in Japan and prohibitively expensive elsewhere.

Sound signature (Skip if you don't care) - warm (recessed treble), neutral (even bass and treble), bright (boosted treble),  mid-centric (recessed bass and treble).

Past headphones (Skip if you're lazy) - What have you used in the past? What did you like about them and what didn't you like about them?

Willingness - do you prefer to buy a product that sounds as it should out of the box, or are you willing to mod it, like adding seal to earpads, to get the intended effect?
