Thats not an isolator but it should remove noise as well. it will change the tonality (Frequency response) of the ZS10 though as it is a hybrid.
ZS10 is an ancient iem and has been outclassed by similar priced iems many years ago.
The Simgot EW200 is a great budget iem and one of the best value out there atm.
I do not know if it will have noise though but if it still does you can just get another dac/amp for it such as the jcally JA3 or an apple dongle.
Ok i return the ZS10 i gonna take the ew200 to try but i don’t want to change my fulla tbh it work pretty well for my use
I just received the ew200 and it does the same i found this on amazon https://www.amazon.fr/Conducteur-Adaptateur-200-ohm-résistance/dp/B0CMCMFCB5/ do you know what Ohm should i take ?
Thanks
You have a really bad source then or perhaps it is due to ground loop.
iFi Audio Groundhog should solve the latter issue
iFi Audio iEMatch will solve the first issue
As for the impedance adapter you linked, 75 should be enough.
Best would be to just swap that source out, the Jcally JA3 for example or the Fiio JA11.
Right now i use this https://www.amazon.fr/Besign-Isolateur-voiture-Système-domestique/dp/B06XQYN77L it work but it feel like i lose some audio quality
and my dac donc have usb c port 
You plug it in to the PC.
Yeah but the fulla don’t is only micro b usb i think cannot use jack with it
Just plug it into the back of the PC, NOT the fulla.
Well i want to use my fulla not bypass it
