i think every one of us hears in his own unique way. therefore the only thing left to us, is read every subjective opinion here and make ourselves what iem is good for us and our hearing tastes. i , for instance , like neutral sound . reading threads here back in 2010 i decided to get some neutral iems. i am completely happy with my path. so should everyone here do , i think. there is not one universal truth , especially when one's hearing perception is involved. read,think,evaluate,try. repeat ad infinitum.
