Kite 2 v16 Is Now Available

Kite 2 v16 OTA is now available

We are excited to announce that firmware version 16 for Kite 2 is now available through over-the-air (OTA) update!

The update can be installed free of charge through the Yinbei app.

What's New In Version 16

  • Battery life increased by ~36%. You can see the extended battery life in Yinbei v.2.7.1 for Android. If you are using an iPhone, the battery life is still extended but it will only be visible after a future app update.
  • A more smooth and comfortable listening experience thanks to countless tweaks to our algorithms.
  • Optimised how Kite 2 handles volume adjustments based on 20,000+ hearing profiles so that more users can find their most comfortable setting. Your preferred volume setting after updating might be slightly different from before. 
  • For those who use Kite 2 without Personalised Sound, the volume controls will now cycle through the most common hearing profiles observed in senior citizens. However, we still strongly recommend completing a hearing test in the Yinbei app to hear more clearly with Personalised Sound.

How to Install Version 16

To get the most out of your Kite smart personal sound amplifier, we recommend that you install OTA updates once they become available. You will be notified within the Yinbei app when a new OTA update is released.


You will need the following to install OTA updates:
  • Kite smart personal sound amplifier with at least 30% battery remaining;
  • The smartphone to which your Kite device is paired;
  • An internet connection; and
