if you are interested in SE535 still, I have limited edition, it absolutely have no bass when it is driven from most headphone outs, but if you have higher quality souce or amp, you can have all goodness of SE535 particularly mids, soundstage, even highs alongwith unoffensive bass which is complementary to the music. For Bass, among what I tried PFE232 with black filter has good bass but still the cheaper Brainwavz R1 has much better bass due to its dynamic drivers, never heard TF10 so can't compare R1 bass to it. Still if you want something cheaper on bass front my suggestion would be R1 or JVC has many bassy models inc FX700 as suggested by others.
