I find it annoying that the right and left are not clearly identified. Similarly the cable does not indicate which is the right or left plug. The marking don't need to be garish, just visible.
I've only had this headphone for one day and don't yet have a comment on the sound.
MDwyerThe cups aren't symmetrical so it's pretty clear which is which in my view. The cable has both L and R indicators, not very well marked but they are marked.
