My observations with Mojo-Poly in terms of erratic RFI and other noises:
For instance if I disconnect Poly from a WiFi network there's a hick-up, when it's being connected to one you can hear the chirping and taking the mobile phone close to the Mojo/Poly and you pick up all sorts of obvious RFI noises with the latter had always been there ever since I acquired Mojo.
I don't have any of these issues with my other HiFi gear. I shall re-run some tests and report back if my other gear has similar issues.
I don't remember if I was having this discussion with you or others, but I had constant rfi/wifi interference issues with the mojo and poly. The mojo very specifically would pick up interference from my phone's mobile radio when plugged in via USB and the poly seemed to have interference specifically from whenever wifi was active and sending/receiving data. For instance changing tracks would have noise since I assume data is being transmitted then. Also when scrolling through the dlna library on my phone.
I should also note that the interference was only noticeable on my more sensitive iems. My campfire iems definitely picked it up. But my final e5000 which is less sensitive was much better and my something like the senn hd6xx I couldn't hear any interference at all. The campfires also exhibit some hissing (specifically the atlas). The interference was bad enough that it really disrupted the listening experience for me.
Must just be the way these work with more sensitive headphones. I too didn't hear interference on other source gear even when streaming. Most recently on the fiio m9.
I picked up an iematch recently to see if it would help, and it's made a world of difference. No more hiss and no more interference at all as far as I can tell with my atlas. I know they change output impedence which can affect the frequency response on some iems, but for me since my primary is a dynamic driver I don't think it has much if any effect there. Either way, that's my recommendation here since it seems the interference is just something that comes along with the mojo/poly with certain sensitive headphones.
