I hope so, I ordered the Gemini multi pack. The ZSN(nor the ZSN Pro), aren't on either chart. But the fact all the KZ models they do list, are all on the Mercury list, with nothing on the Gemini list. I'm guessing I should have checked first, and they will be too small. For some reason, the way I read the note about the sizes, I thought they were referring to the Mercury, as being for true wireless IEMs. So, I assumed the Gemini was for wired models(I have a ridiculous HP "collection", but I know nothing about IEMs). That's what I get for assuming, unfortunately. At least I basically got them free, using my credits. I need the foam tips, as the silicone they came with wouldn't keep a seal, even with the smallest size, so I still haven't been able to really check them out. But, I was really surprised with the SQ, from what I was able to hear. I might have to look into them more, I'm really looking forward to hearing what they can do. But, sadly, I am not expecting the Geminis to work on the ZSN's, after doing some checking around.
