The Beats Pro aren't known for their bass. My Denon D1100 has more bass than that.
The Pros are actually a pretty nice pair of studio headphones, albeit having a higher price tag than Shure, Audio-Technica, etc. studio headphones.
If you want bass, you'll want the Beats Studio, or the mentioned Ultrasone, Beyer DT770, Denon D1100, or M50 headphones.
