I wish both the H3's and the FX850's were smaller. I like to use my iems a lot outside or at the gym, and I doubt that I would be able to do so with either one. I find lighter and smaller profile iems to be so much better for that. For instance, the vsd1's are so light that they stay in well, they do not stick out of my ears like bolts, and when not wearing them, I can leave them hanging from the shirt clip without hardly noticing them. All of my better sounding iems are huge and heavy monstrosities in comparison. So I'm waiting for one of you guys to discover something that sounds as good as the H3's and FX850's, but in smaller and lighter form factor. The AKG 3003's come to mind. The only problem is that they are $1300 lol. Edit: I just read that the 3003's don't have a replaceable cable. What were they thinking?
In case you were wondering, the H3 and the K3003 don't really sound anything alike except having a somewhat similar FR. Though the newer K3003 seem to haver less bass than what currently published measurements show.
I'd put the K300K bass at about the level of the EX1000 (see graph).
