Guys
I am new to headphones.

I recently aquired a Sony Ericsson Xperia X1.
The sound is good but.. time to upgrade

I want music, not detail. I have tinnitus and to much in the highs hurt.

I need advise
to make it easier.. here is a list of wants and should nots

Requirements
Circumaural (open or closed back)
Comes with a 3.5mm Jack
should not drain my phone too much ( i sould be able to use it after listening to 3 complete Albums)
Foldabality is a great plus, I could take it on flights
Should not be dry sounding .. I listen to heavy metal most of the time), prefer rich sound with tight bass
High should not make my ears bleed
Bass should be tight amd punchy
costs less than US$400


If you guys could give me some suggestions, i'll run out and test the recommended units

So far, my search has yileded
Bayerdymanics DT860
AKG 271


AKG701 will reguire a potable amp and so will th Sennheiser HD650.
this makes things more difficult to porta-around

Please advise
