I get a replacement for the dongle, how can I connect it to the headphones?

1. Plug the newly received dongle in PC, it should be flashing blue rapidly (If not the case, please refer to Factory reset the DG10). That means it's in pairing mode. 

2. Turn on the Headphones, press and hold the volume + and - buttons simultaneously for about 5 seconds until the LED turns PINK, indicating that the headphones have reset. The headphones should then go into pairing mode and the LED will alternately flashing RED & BLUE.

3. Put the 2 devices together and wait, they should be connected in a few seconds. Once connected, the LED on the dongle will turn solid blue.

Enjoy the headphones!
