Or you could borrow a friend's Android phone and tune it up for once.

JA11 uses integrated chips

As you can see from the picture, your KA11 works in UAC1.0. Do you have an Android phone? Connect the KA11 to your Android phone and run the FIIO Control APP. Change the working mode of KA11 to UAC2.0

Does KA11 work on your windows computer? Listen to music

KA11 doesn't overheat either. If your KA11 is hot. It could be a malfunction. In addition, JA11 will be cooler than KA11.

If you encounter any problems during use, you can try different phones or computers to troubleshoot the problem. If the problem is confirmed, you can contact us via private message, and we will do our best to provide you with service.

If you have R7, R9, K19. It's also very good with this power.

This is KA11.

Maybe the next model. It may be that this feature is solved first in KA15.

KA13 is also very good:)

Thank you for your attention. The goods have been shipped for a week and are expected to arrive at Amazon warehouse in early May.

We have tested and found this problem. We are analyzing whether there is a BUG in Tidal APP or our device can be improved. If there is any progress, we will share. :beerchug:
