Ive been at the amazon checkout page, looking at getting the DT-990 + e7 or the HD 598 + (maybe a e6). I love the looks and the comfort of the headband of the 598s, I have put them on but not listened to them (I know, weird right?) I feel that the HD 598 are the perfect buy for me. Everything about the HD598s is perfect, except for the fact that I do enjoy a little bass. The HD598s are lacking bass and I know that, that is why I am looking at the DT-990 pro with (possibly) a e7. I do not want to miss out on the warm sound of the 598s for the trade of some bass. Thoughts?
