Great sound, comfort and isolation if you pair this earphones with Comply foam tips. Very accurate midrange, a bit light in bass region (I don't mind this), exceptional sound overall. This is my second pair and I gave this earphones as a present for a couple of friends too, everyone is happy with Etys.
So I have the apple dual drivers ear, I also have the beats by dre, the low end bose, the Sony noise canceling.
These are better. Be prepared for deep insertion, it feels a little funny at first but I no longer hear annoying people on the subway.
