Splashy, it's possible you might have something wrong with that pair, but in case you don't know, open back headphones don't have as much base as closed headphones. If you are looking for serious bass, the current king is JVC SZ2000. I think the consensus is that open back headphones have a nice realistic soundstage with lots of detail. I needed open back headphones for family security and I really like the DT-990's. In the near future, I'll probably get a 2nd pair for when the family is not in the house and I can afford to shut out the world.
BTW, did you alter your Windows sound EQ? I did, as a flat EQ was too weak in the bass for me.
