So this is my first review guys, and that's because I finally have a useful comparison to make! With Sennheiser's release of the 630VB, I caught the bug to get a high quality portable pair! However, I never pay full price and almost always buy used, and I was not about to pay 500 USD for a pair of sennheiser portables (My HD600s I got for 240 USD on ebay and I bet they are better then the 630VBs).  So began my search, I really wanted an audiophile grade closed back headset for portable use, I have Audiotechnica Ws99s which are a lovely bass...
