I tried the Jackomik mod, I used some silicon tube that wrapped around the metal nozzle then some thicker tubing to sandwich the needle tip and hold it firmly in place. I'm tempted to epoxy it to the silicon just to be extra sure it won't fall out, but it feels very secure now. It's sorta a modified Frankenstein tip now.
I used a 0.64mm dia. needle tip, (as well as trying out 0.4mm, and 1mm)
The 0.4mm didn't make a big difference, more airy treble response (similar to going from Green knowles to Brown)
the 1mm tube was too open and completely killed the bass response, as well as killing the isolation of the iems.
the 0.64mm is my ideal, I have only used it for 24 hours so far but it increases the sound stage as well as brightening up the earphones. I've gone from brown Knowles to green with a damping foam from the stock blues in each side. I've mounted them into the existing white filter tube rather than using a cotton swab. I think the green and foam is the orignal stock blue filter but at some point it got changed to white cloth in the blue filters.
It increases the sound stage massively and totally removes ear fatigue, because the pressure equalises. Everything sounds clearer and more naturally layered, the sound stage doesn't get wider but deeper, it's not easy to explain but the sounds are layered with more space between them, instead of previously where they sounded intimate (but in no way closed). There is no trace of any veil characteristic to the sound.
I find myself looking over my shoulder occasionally because in some tracks I'll hear parts of tracks that sound as if they're distinctly behind me.
I'd definitely say this combination of mods has completely opened up the earphones to their full potential.
