We have not tried swapping the reference filters James between the older and newer Aki k 3003 .
We compared the old and the new badge with their filter , and we found out the sound quality in the newer badge more balance and less harshness .
Tomorrow we will compare our Akg k3003 new badge vs Fit Ear to go 334
We want self hear the sound quality diffrerent between two universal high end iem
The impression we will post by tomorrow night
