I love mine . The shell fits me perfectly. I had to get rid od the cable and am using the cable from my husband's ZSA. It has the angled connector that is smaller than the regular ones. I also had to use Spinfit tips...the first pair I used them on.
I think they are special but I don't have a ZS5...neither version.
I've been using the ZSA cable too. Went with Spintfits for a while but ended up swapping to some long bi-flange set instead. This is one of the few iems I've had to resort to that with. My ears really seem to dislike these vertical style housings
