I've realized that the iem market moves way too fast for me and much faster than the full sized market. Some products here become irrelevant very quick while I can't say the same for full sized. I wonder when my JH5 will be long forgotten at the rate things are going :P
I do wonder where you find the space for all the iems and how you find something if you are looking for a specific one.
I'm have a JH5 too and I'm still very satisfied with it's performance against many high end universals. But some earphones like the W4 or XBA-3/4 can outdo it at times for certain music.
