If you take ur headphones off and hold them open (don't let the cups seal on each other) that about how loud they will be, maybe a little louder, the other issue is you will be able to head everything. I'd say only the HD600's would NEED an amp. What about the Sennheiser HD25-I-II's or Amperiors? Or V-Moda M80/M100's?
