Yes, the BTG Starlight cable is for CIEMs; I have one personally for my V6S. I prefer the stock cable though for the V6S - the Starlight sounds slightly more forward in signature than the stock cable. Currently looking for a new cable to replace the stock and BTG cable too.
I also have the V6 Stage (universal fit) and tried multiple upgrade cables on it...
The copper (brown one in the picture) Rhapsodio Panther MK2 is still one of my favorites on it so far
Great synergy imo
