$399 vs $299
 
Which one has a better tonality, bass response (tight and impactful), comfort, and lack of sound leakage?

do u have an amp...or portable amp? 
oppo3 shines with a the HA2

Yes I do, but I don't want to post which one (nor am I going to buy another) since a good headphone should sound good with any neutral/solid state amp. So, without the amp in the equation, how do these two compare?
