I got these three days ago but im pretty dissapointed with the bass. Is there anyway i can add more thump to these headphones. ANd if i cant what headphones can i trade these for or get for around the same price.

I bought this amplifier today on amazon and im getting it in the mail and now im worried. Im not sure if i can actually use it with my htc hd7 and my sennheiser hd 598. Does it do the same thing the e5 does. There are plenty of video of the fiio e5 amplifier.  Sorry im new at this audiophile stuff.

I got my sennheiser 598 today and i plugged it in to my htc hd7 and there kinda too quiet. Will an e5 amp make them louder. Im a noob at this high end audiophile stuff but i want to enjoy my music to the fullest. These are my first expensive pair of headphones. I usually dont spend more than 30...
