Argon's? DT 1990? "Bass" is pretty nebulous, in the sense of that you could mean quantity, extension, speed, or control. If you can handle the highs or use EQ to tame them, the DT 1990 is a hard headphone to beat without more than doubling the cost. The Argon doesn't have the piercing highs, and has a larger sound stage, but it also lacks the speed and treble detail of the 1990.
