Exactly... I love the neutral sound of my sennheisers, I have several different models. I can't understand how people shell out for bass heavy sets like beats and monster.
If I want more bass on my sennheisers, I use my EQ to help them out.
I will be honest, I am enjoying them more and more (Bass boost has helped this) as I toy with settings and sources. I think if anything, I will amp them and then just keep them and upgrade later.
One thing I am thinking is maybe I overrated the need for positional audio in gaming and may get the 600 or 650's.
