Which balanced output to be precisely? 4.4mm? Or 2,5mm? Will the sound from 6.3mm different to the K5 Pro? I'm trying to have an idea how different because I own the K5 Pro.

Looks like XLR and 4.4mm from the pic to me.

1，4.4mm
2，I think it is different to the K5 Pro，The output earphone model is different and more powerful, so there should be a difference in sound。

Do I need a voltage converter to use it in Japan?

The K9 Pro has a built-in linear power supply with the option of 110V for use in Japan.

@FiiO Willson I vote for a Burr Brown version!

Will K9 land in the EU shop at launch?

In this image, you can clearly see a USB type C port on the right side of the K9Pro, which means this device has dual USB inputs! Great for connecting to both PC and mobile phone/tablet.

I wonder how do I switch between these 2 USB inputs without manually plugging the cable. Maybe through the app or the button in front? But I only see one USB input light indicator so @FiiO Willson could you let me know what is the method of switching between these 2 USB inputs and any indicators to tell which one I am connected to?

Also, please announce the release date soon!

hello.
This is a photo taken by a user at the Shanghai hifi headphone show, right?

Yes, the K9 Pro will have two USB ports, a USB B port for connecting to your computer and a Type-C port on the side for connecting to your phone.

The current order of priority is that when the computer input is paused and the phone turns on music, the K9 Pro will switch to the phone input, and when the phone is unplugged, it will automatically switch to the computer input again, you don't need to switch on the APP or manually.

But this is a very detailed operation, and it will depend on the final product experience if this is the case, but I personally think this is fine

By the way, the K9 Pro was very popular at the Shanghai show, with many people queuing up to try it out

The AK4499 is currently available in very limited numbers, only a few hundred units worldwide, so please note to contact your local agent when we officially launch.

Thanks for the explanation @FiiO Willson!

Would it be hard or even impossible to add a toggle button in the Fiio control app to switch between the two USB inputs so I don't have to manually pause or unplug the phone/cable?

Hi
I confirmed with our engineering that the USB input will eventually be defined, with the side Type-C input takes precedence by default. When the side phone is plugged in, it will give priority to the phone's output; and the computer can only output when the phone is unplugged

This one also makes more sense to us.
There's no need to make a choice in the APP either

@FiiO Willson Have you considered providing a shiny golden volume knob option? I think it would make the product stand out, looking more premium and less prone to showing fingerprints.
