Experiment time:
Faraday tape inside the silicon case... let’s see how this goes.

edit: so... every time I slide the s1, the faraday ended up moving, so I ended up placing it around the s1 (it bumps me since I don’t want it to stain with glue, nor loose my code bar) tested it in my kitchen since I used to get efi there.. USED TO! I won’t say anything yet, but I think we got it guys. will tell tomorrow around my day.

update: so there’s a little bit of efi still, but its not cracking my ears as it used to. I do recommend doing this if you are experiencing crazy amounts of efi with your unit

You don't need casing to avoid interference. Get "EMI shielding tape" from ali express, unscrew 2 screws on the bottom of S1 and shield it from the inside. There are no wires connected to the shell of S1 and you can easily take out the board with it's screen. Regards cable WooAudio USB-C to lighting angled cable is way better then stock one and I got no problems anymore to keep my phone and S1 in the pocked while on the go.

I strongly advise to do these things if you want to have a good portable solution to be used with phone

Can you share some photos of what you did as well as links to the tape?

Just type in ali express emi tape and choose the one you prefer they all should do a decent job

Wich cable is this one ?? It has lightning conection ???

That's the usb-c to lighting connection from wooaudio, I shipped it from usa. A bit pricey, but worth it, thick and angled connections seems will last a long time. There is no audible difference for data cables, but with proper angled cable I can easily use S1 outdoors

Does the EMI tape have a non-conductive coating on it? I don’t want to line the interior of the S1 case with a bare conductor for fear of shorts...

No it doesn’t, but board sits tight in the shell of S1. I’m just curious what sort of modding is being done to S1, I think I’ve read in this thread that cables are being replaced, but I see none of them....

Did anyone tried S1 with full size headphones in balanced mode? What headphones exactly and how how the synergy? Looking forward to the next firmware update, let's see what other features will bring along.

Since I use this portable I've really only tried it with my Aeon rt closed and at 72-76(depending on music) it runs perfectly fine off my iPad. Sound out of the aeons is very good. Still not quite there vs a desktop amp but I’m still impressed off what I get from the small power the S1 pushes out. On my iPhone X it will actually restart the S1 above 71 volume in high gain. This is due to the iPhone not pushing enough current out of the lightning port. Thought I’d throw that in there since I don’t see too many people using this with their iPhones on full sized headphones.

No issues driving my Audioquest Nighthawks from my S1 connected to my iPhone 11 Pro max. The headphones are fairly easy to drive and they sound great.

I'm hoping with an upgrade to the upcoming iPhone 12 that it wont freak out and restart past 71 on high gain.

use it to drive a zmf eikon in high gain. am impressed given this small dongle but can’t compare to desktop amp power

Anyone who will want to get rid of EMI noise using phone, you need to cover parts of S1 as shown in photos. Not sure if it's related, but using balanced mode, sometimes S1 would randomly turn off, especially when I'm moving. S1 board is screwed only on one side, the other side is held by 4.4mm and 3.5mm connections, but in my case these were not sitting tight and board components were touching the shell of S1. Same thing would happen even without inner shielding, but on very rare cases

I would be cautious about lining the inside of the shell with a bare conducting material for fear of electrical shorts, especially if the board is as loose as you observed.
