My Es-100 is frozen in the on position. The green led stays lit constantly and none of the buttons work. I can't connect with any devices It's bricked.
Is there a way to reset it without connecting to the app? There must be some way to turn this thing off.

We've been working on the system freezing issue, and the next F/W update would have reset on frozen.
Assuming every corner case, we hardly can prevent the system freezing.
But at least we may able to reset the system after a few seconds after freezing.
We'll release the next F/W update early next week.
Please let us know any freezing issue before and after the next F/W update.
Thanks,
WS

Connect a usb cable to it (that's connected to charger or computer)

Edit: I probably was reading wrong documentation - https://www.head-fi.org/threads/radsone-earstudio.867366/page-75#post-14237690

So I just found that pretty much all balanced 2.5mm connectors made as L-,L+,R+,R- while EarStudio is

So unless one specifically requested connection as above - it will be out of phase.
Standard Shure and Sennheiser balanced cables are going to be wrong.
Test it here - https://www.audiocheck.net/audiotests_polaritycheck.php or better use any multimeter and check where your grounds are.

What you show is the Astell & Kern 2.5mm TRRS Standard wiring. So, looks like Radsone ES100 is using that standard.

FYI, the following DAP's use that same 2.5mm wiring for their 2.5mm Balanced output jacks: A&K players with a balanced 2.5mm output, Fiio X5 3rd Gen, X7 (with AM3), Onkyo DP-X1, Pioneer XDP-300R, Cayin N5, The Bit Opus #1 DAC, Luxury and Precision L3 DAC; ( and probably a lot of other newer devices with a balanced 2.5mm output )

Been enjoying the ES100 for a few months now and just performed the latest firmware upgrade. Norton Antivirus program loading on my Win7 PC flagged the firmware application as malware and deleted ths file. I temp disabled Norton and the firmware installed fine. Should I be worried? Firmware download was directly from the Ear-Studio webpage.

So I have both the ES100 and FIIO Q5 with AM3...are the balanced outputs wired different in these? AM3 = A&K and ES100 = standard trrs?

Now, this is really confusing. If you read manual - it shows different pin-out (from DualDrive description PDF)

But for some reason, it was not sending a signal like that for me. I need to double check tomorrow.

Edit: Ok, I think I know the reason - I was using the picture above from DualDrive description
10113204.png

and ordered Sennheiser cable like that and forgot. Which made it wrong polarity (I found that later) and L/R (I switched plugs in the beginning). So I've checked with multimeter Shure cable and found the same grounds at the outsides and made the wrong assumption about the whole thing.

I will double check that, but so far it sounds plausible and 2.5mm socket of ES100 probably standard AK2.5 according to manual.

For what it's worth (probably not a whole lot), Today I both learned that there are different types of balanced cables for headphones today and I also tested the cable I'm using on the sound test referenced earlier. The cable I'm using ( https://www.amazon.com/gp/product/B076SHDYTF/ref=oh_aui_detailpage_o08_s01?ie=UTF8&psc=1 ) at least seems to be the compatible type of wiring that that the ES100 is expecting, and my shure 535s.

Edit: Ironically this is my first ever actual post here, even though I created my account back in '06. -cheers!
