The pairing has been a problem since the instructional manual guide or tutorial book is in Chinese language and many did not understand so i made a simple and quick video guide how to pair them together simultaneously so watch the video down to see how easy you can do it yourself in less than 30 seconds.
Also you at the start of the video you can see how to power on and off the wireless or bluetooth ear buds.
This will work on both android and ios devices since i have tested on both devices or platforms.
