I own those too and don't allow anyone on this forum to try and make you think you made a bad choice. Considering their price they are a fantastic deal, much better bang for the buck then Senn HD650 ($550). These forums can be so damaging to your wallet because for every headphone you name you will find posts that will steer you wrong making you think you need to buy something else, they will tell you they are bad for some reason or another.
I come here thinking maybe it is time to upgrade my headphones but now I find I can't even make a choice because every headphone I think I might like I find too many negative opinions. People said HD598 is so much better than HD595. I bought both those headphones. It is not true that 598 are way better than 595, I compared them back to back and not from audio memory of years gone by, not to my ears anyway. Now I don't own either of those headphones and only reason I bought them was because of comments about them here. These forums are a a double edged sword.
Now I see people saying thse newish Sony MDR 900 sound like HD650 and are good but then I see others saying they are just average and nothing special. I can get those for $200 USD compared to HD650 $550. But who to believe? Can't got to the store and make my own informed decision so am stuck with comments from this bipolar forum.
