New Head-Fier
Have been through many IEMs. It clicked with ER4P. Got ER4SR/ER4XR/ER2XR. ER4SR with balanced cable is used with DAP. ER4P plus resistor on VALI2. ER4XR for outside. ER2XR with iPad for sleeping. All I can say is they are all coherent, balanced, detail and musical. They definitely have difference. But for me to enjoy blues, jazz, classical rock and some new age, they are the best. ER4SR is my little preferred over other three. I am really glad my ear can take the beaten of Etymotic IEMs.
