Well, I decided to try the fischer audio DBA-02 black silicone tips on the UM3X RC and I'm WOWed. Compared to the SHURE Olives, theres TONS more treble and details, more air (more space - can't explain any better), better perception of instruments such as cymbals, percussion, etc. Everything sound more natural and realistic. It's a totally new IEM for a much lower price than the UM56 custom tips and sound is pretty much the same.
Isolation is medium, the UM56 isolate a bit more, but if you're like me that listen at high volumes, that won't be an issue at all. I can't hear much noise (if any) outdoors at the volumes I'm accostumed to listen to. Nothing that distracts me from the listening experience/enjoyement.
I have tried almost all the universal tips on the market and nothing compares. If you can, get these tips and thank me later ; )
P.S. I had to do some DIY, since the tube is a bit larger than the nozzle (I've used warm glue - it does not damage the IEM, its like silicon), but it's worth it. I prefer these to the UM56's due to comfort. I can't feel them. Add to this a Chris Himself's Silver Cable and you won't recognize this IEM (instrument separation, definition/detail and bass on the UM3X RC is unlike anything else. I've tried SM3, J-phonic K2 SP, Sony EX1000. etc, and difference is night and day IMO).
