The sound is balanced, bass are not as advantaged on the 212. It details the instruments and sound does not come out porridge.
I'm not very trained ear, but I find that listening to mp3 encoded relatively well (> 200 kbit / s) is good. In flac is also very good. I have not tested chain Hi-Fi.
At normal volume, you can not hear what you are listening to more than 50 cm from the headphones so no gene for the entourage.
Very satisfied, 5/5
