I know, the question seems to be just a repeated one again and again...
What I am really interested in is the find the IEM which offers the best noise insulation and then, the best sound as a secondary criteria.
I can not find any details on the Klipsch x5 and x10 noise insulation factors. The Etys are really good for both noise insulation and sound quality, but is there any other IEM that have an even better noise insulation.
I had even check in custom IEM but they just offer 26dB, not much. Not enough for this thread. So I guess that also eliminate the SEs.
