For any CA fans interested in getting custom eartips for their CA IEMs, I just got mine in the mail. Pic and review below:
Finally got my custom eartips from Campfire Audio. Took about two weeks from overnighting my impressions to receiving the final product today. Fit is fantastic (not as godly as my 64 Audio A12ts but still fantastic). Isolation is better than the foam tips but not nearly as isolated as a CIEM. Sound is nearly identical to the CA foam tips (I put a foam tip on one side and the custom on the other and then swapped, there was no discernable difference between the two. All in all, it cost $150+20 shipping (plus cost of getting and shipping out ear impressions).
I have large ear canals so getting this was absolutely worth it. Comfort levels are OVER NINE THOUSAND and there's no longer the sensation of eartips moving back and forth thus resulting in having to readjust my IEMs every five minutes if I move too much. This purchase, for myself, was totally worth it. YMMV.
Note: I was originally going to buy two pairs (one for my Andromeda, one for my Vega), but CA told me it wasn't needed as one pair can fit on both nozzles, so kudos to CA for saving me $150!
