I am looking for either IEMs or headphones that have deep, powerful bass. I guess my reference is the XB500, which I unfortunately never got my hands on, but was able to try. These are basically going to be my fun iems/HPs for dance, edm and hip hop. My budget is $50-70.

Have a look at this comparison thread. It's very informative:

Scroll to the right and it will tell you the IEM characteristics...whether it is bass-heavy etc.
