Compared to the previous generation of products, we made the following improvements:

1. Improved use experience. Before, when user changes ringtones, and hold Music Button over 3 seconds, it will trigger clean pairing function, so wrongly believed the product damage, but is not. We improved the manual and extended 3 seconds to 5 seconds.

2. The span of 4 levels volume is more wider, no longer concentrated in  short interval, so that it can be more quieter or more louder.

3.Apart from "Ding Dong、Ding~Dong~,etc",we added in more  ringtones,just like chord,jazz,folk music and so on,to meet the individual needs of customers. 

4. The communication range is farther and the ability to penetrate the wall was enhanced.
