After going through a lot on these forums i find ultraonse hfi 580 is the best headphones for my preferences(hip hop/rap) and price
Will be buying the ultrasone hfi 580 in few days but I wanted to know if there are any iems that can be better than hfi 580 with higher bass and good sound under $150?.
I am happy to provide any more details needed to help me out in this.
Thanks

Here is the HFI 580 charts.

Here are the charts for the Brainwavz M2:

The bass goes deeper on the Brainwavz M2 seen in the frequency response curves, but you loose some peaks in the treble.  To some this may be a good thing as high peaks in the treble can lead to ear fatigue.
 
I own a pair of the Brainwavz M2 and really like them especially paired with a set of Comply T-400 foam tips.  With the foam tips you would be looking at a total cost of $85 or less.

I personally think that you can't go off Frequency responce and graphs alone and would need the headphones and IEM's to make a proper point of what can be similar. Take the KRK 8400's graph...... You can compare it to many bassy headphones and what not and even the HD280 pro, but they aren't bassy. 
 
It doesn't compare, but I liked the sound of SoundMagic, and also have the HFI 580
