Is there any way to revert to the previous firmware? My ka11 is basically useless right now. At this moment is not recognised at all by my Phone. It has started with music reproduction stuttering, and now if it's connected to the Phone the light turns blue and the device gets warm very quickly, but nothing else happens.

This should not be a firmware issue, there may be a malfunction. Can the connected computer be recognized?

Anyone tried the Anker lightning female to USB c male adapter to see if it works, for like firmware updates?

You can send me the product link and I'll confirm it.

KA11 Lightning version can not upgrade the firmware, there is no problem at present. The Android version due to different Android phone manufacturers, the volume value is not uniform.

 

[FiiO Kang]

If you have the adapter that comes standard in the KA1 package, it can also be used to connect the computer and upgrade the firmware

The Anker USB-C-to-Lighting Audio adapter does not work with the Fiio KA11-Lightning version. That is not really surprising given the fact that the adapter is actually a USB-DAC for the host device (your PC, phone, ...) and a host device for the Lightning-audio-device (your Lightning-earphones or some (very few) MFI-certified DACs) - thus a surprisingly complicated device that acts as a "man-in-the-middle" and electronically translates all the signals from the host to the audio device.

All compatible Lightning audio devices are listed in the product description and there are not really any other ones working. I use it with the Audeze iSine10-Cipher "cables" (DACs) and it works for that but not for many other devices. The same holds for similar "active" male USB-C-to-female Lightning adapters (like e.g. the "RAYZ Lightning to USB-C Audio Adapter" or the one recently released by Apple).

I have had the KA11 for 2 weeks and was enjoying it.... WAS. Now it keeps cutting in and out and is getting extremely hot. Yet once again a throw away product after just 2 weeks. Thanks Fiio.

It's not recognised and gets extremely hot in few seconds

Dear friend,

Are there any certain operation before the issue happens? Did you drop the KA11?

Best regards

This one won't work. It must be an OTG USB adapter.

No, it was handled carefully as I do all my equipment but thank you for the follow up, I have already returned it. I would like to try this unit again, if it becomes available via Amazon, do not want to wait for the shipping time again and if there is any issue, it is a quicker and easier return process.

Hi all,

New to the forum, so sorry if this is in the wrong place. Just a heads-up that I bought a KA11 on AliExpress from the Fiio store. Really disappointed. I have the lightning version. Sound was absolutely fantastic when I first plugged it in. Then after about half an hour of use, the left channel went to a low volume level with heavy distortion. Same thing happened on one or two further uses. Now when I plug it in to the iPhone (11 pro) although the light comes on, audio is not rerouted out of the DAC, and just continues to come out of the iPhone internal speaker. I have tried to raise a dispute on AliExpress three times - but the best they offered was to return the DAC to china at my own expense. I paid around €30, and that is almost the exact cost to return it to China from Belgium. So a lousy first experience for me of Fiio. Faulty product, and a refusal to do the right thing. Quite surprised as they have a lot of fans on here and other forums.

For ref, I am using a pair of DT-770 pros from Beyerdynamic, which work perfectly with other devices, and with the same phone through the Apple lightning to headphone adaptor. Also FYI - I have also tried the device with my iPad - same problems. Both phone and iPad have latest version of iOS. Fiio also suggested I update the firmware, but offer a PC .exe file to do this. I have a mac. And there is no way to connect the lightning version of the FA11 to a computer in any case, unless someone knows how. Perhaps with a lightning to USB-C adaptor. In any case I haven't seen this issue reported elsewhere, so I think it's a fault not a firmware issue.

Cheers.
