Well guys, I signed up to this forum a few weeks ago and can honestly say it's easily one of the most, if not the most best/most informative forums/websites I've ever come across.
As a student, money is a factor and I wanted to get my first real audiophilic investment as correct as possible and in the end, settled for the Ultrasone PRO 2500.
They've been discontinued for a while now and replaced by the 2900, but that played to my advantage as they were £150 cheaper than the 2900

I figured it wasn't worth buying the 2900 for that much extra.
It wasn't easy, I twice cancelled orders after having second thoughts/learning something new, first with the K701's (not enough bass for my needs I read) and then the HD650 (difficult to power and also not the most lively headphones I've heard). I settled for the Ultrasone's, which actually surprisingly were the first headphones I considered. Love at first sight
So yeah, they will arrive soon and I also will probably get the Fiio e7 and e9 combo as I need an amp for around £100 as it's all I have left and I heard it's decent.
I hope I'm not dissapointed and that I've made the right choice, and I'll definitely be back here more often, posting more questions if I need info, and maybe, just maybe one day I'll have sufficient knowledge to answer some questions myself

Or maybe not haha!
But yeah, thanks everyone for your help! And thanks for getting me one step closer to bankrupcy
