Hi. I need some suggestion. I listen to all kinds of music and I'm looking for earphones which do everything perfectly. I want them to satisfy me when listening to metal,rock,r&b,trance,classical,instrumental etc. They must be airy,detailed,easy to drive,comfortable. I don't want midbass hump that ruins some kinds of music. So, these are my expectations. If there are iems which contain the characteristics above at this price range, please let me know. By the way, I would be very happy if I could buy them for $150 or so. Thanks in advance.
