Sound excellent, headphones still not perfect

First, the reasons for which the part in my opinion is not perfect:
For my taste, the headphones are pretty tight. I do not want to have to carry him a few hours at a time. The faux-leather one sweats also on the ears.
He also shields external noise surprisingly well, which has advantages and disadvantages - as you like it halt. In the subway, I would like it. :-)
A drawback for me is that a cable leads to each ear. This can be solved differently.
A drawback for me is that are not labeled left and right, at least I have not found anything.
It has a volume control may not, but you know in advance.

For Sound: In a word * superior * (hence five stars). I had much more expensive headphones from Sennheiser as (nevertheless good headphones!) Who sounded worse. The complain about the bass I can not quite understand: It deafened yet, but admittedly somewhat undefined. Because of the sound, I would buy the headphones again, despite the disadvantages.

Addendum: You can still see what's left and right. It is on the inside of the bracket at the transition to the middle piece. For whatever reason.
And: It expresses quite badly and I do not have a thick head - at least not a pretend in the headphones hurt!
