Pros: Music sounds great even from poor sources without an amp. It sounds even better with better source and amp.
Cons: Heavy. Makes ears hot in the summer.
Music sounds great with these. They are a little heavy, but I knew that when I bought them. What I did not know was that they make great ear warmers. This is good for winter, but may not be so good in summer.
I'm quite happy with them. They don't seem to really need a headphone amp to sound good which is another plus. They seem to have low listening fatigue.
The sound may be on the warm side, but I like that. I recently tried them with my Bifrost and Parasound pre-amp as 'phone amp and they sound even better than with my Sony NWZE475BLK
