I'm assuming the pro550 has less bass but how much less?
It's been a long time, but I still remember my experience a bit.
Without EQ, actually both headphones have similar amounts of bass.
With EQ, the HFI-580 can be MUCH more impactful. The 580 has the perfect design to really pound bass. The larger design of the PRO 550 disperses a lot of the bass impact and spreads it.
I talk about EQing a lot but these headphones can be more impactful, more detailed, and have less distortion than Monster Beats Pro headphones. Whether or not the outcome of the EQ is good or bad depends on the quality of your equalizer and how you are equalizing.
