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

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...

My ka11 still has problems to be recognised at times (Android Phone). It would be good idea to address this issue. I own a Shanling UA3 and I've never had a problem. Firmware stability could be an issue with the ka11

Ok I've just opened the Fiio control app and I've noticed that they 've added a sort of volume limiter function. I've sei it at maximum and the full range of volume is back. Still, it would be better having everything on Fiio's website, maybe with a note explaining the new functions or changes...

I've successfully upgraded the KA11 to the 0.7 firmware, but the device' s volume is now much much lower, I get some barely decent volume only at maximum output. There is clearly something wrong with this firmware. I would ask Fiio to provide the old one, so we can at least use the full volume...

Hello, I haven't tried to connect it to my computer yet. But I cannot find a proper firmware (or firmware update tool) for Ka11 on your website. The firmware page doesn't list this model but only the ka1. https://forum.fiio.com/firmwareDown.do Could you please provide more infos?

It's the KA11. After rebooting my phone various times, I managed to get it recognised by the Fiio control app, and restore default settings. It would have been useful to have a physical reset button or a special software to flash it when it's bricked. Something similar happened to me with a...

Hello, I recently bought one and after a couple of uses it's not recognised anymore, either by USB audio player pro or the fiio control app. Is there any way to reset it? Seems something wrong with the usb driver interface. I tried on a couple of phones and it is the same. The led light turns...

Here for sale some tubes for your Woo Audio 6se (1st gen) amplifier. I recently sold the amp and tested all the tubes before selling it. Most of these tubes have been purchased from Woo Audio and had little to no use. These should be compatible with Woo Audio 6 (1st gen), according to this...

Hi there,new owner here. I was using the Go Bar with a generic usb cable, longer than the original one, and I wasn't that impressed by the sound, a little brittle/digital. Then I tried the short bundled cable and it seemed so much smoother and organic. Am I immagining this or someone else...

He (or she) linked me a software to fix firmware upgrade problems.

Thank you for your reply. Your suggestion completely fixed my problem. It is good to know that there is good customer support from your brand, makes me confident if I want to buy other stuff in the future.

Hi there, not sure if this is the right place to ask. I tried to upgrade my ua3 to 1.07 firmware and the procedure worked, but after that my ua3 is not recognised anymore. When connected (using usb audio player pro), my Android phone asks me if I want to connect to Comtrue-inc firmware update...

+1 love it as well. I can see from you signature that you also own a Clairvoyance, do they sound similar? I'm curious to know if there are some similarly tuned IEMs around with comparable sound quality.
