Summary: Listened to these for a few hours yesterday straight out of the box, these are my current thoughts:
Straight out of a Clip+, my phone, and a Kindle Fire these sound quite good. Not as good as my other cans, but good enough that I wouldn't immediately start missing my other cans if I just brought...
Pros: Good sound quality, well built and quite good for portable use
Cons: Somewhat uncomfortable, doesn't sound as good as some more expensive cans
