Hey buddy - I did build it.Could you please tell me which cable you used?
I've been looking for something like this but I'd like to confirm if I'm going in the right direction.
I found some on Aliexpress like this one https://www.aliexpress.com/item/32864899173.html?spm=2114.12010612.8148356.11.7c613d9dRGoskj but it kinda look like they are aimed for IEMs.
If you have the link from where you bought yours I apreciate it.
---EDIT---
Forget it, I thought you had build your cable.
Sorry
I bought that cable from Cosmic Cables - here is the link - Ian at Cosmic is a great guy and he can definitely sort you out, see what his quote for postage to Brazil is...
