Thanks for giving me some info about it but, When others listen to my gears they tend to complain how low the volume is, they increase the volume straight away and asked by one of my friend how can I hear the dynamics of the song while listening at a low volume? Somehow this only started when I bought my new primacy, its weird but my ears got sensitive, I dont like loud noise or listening more than 50 percent, I dont like cars raging their car engine or motorcycle engine. But its odd that I hear this high pitched ring in my ears especially when I am at a quiet environment or sleeping with my ear plugs in. I dont know if I change the cable will it smooth out the overall performace? If thats the case I will immediately buy a cable just for me to smooth things out. Thats why at present, I am in search and quest of having the smoothest iem there is especially a reference of a flat one that is close to reality. Also outside with the regular traffic noise, I completely cant hear the rining in my ears. Again its weird, there is a ringing thing in my ears high pitched but im also sensitive to loud noise, very contradicting isnt it? Hehe. Atm my new primacy is in the market waiting for a buyer to dismiss it in my inventory hehehe. Thanks!
