While the StreamBuds DX are charging, a red light will appear on each earbud. Once the red light has switched off, the earbud is fully charged. Each earbud has its own battery and may take a slightly different amount of time to charge.
Firstly check the earbuds are deleted from the pairing list on the phone. Place both earbuds in the charge case and leave the lid open, the red charging lights should be on for both earbuds.Tap and hold the back of both earbuds at the same time and hold for 8 seconds, the light will flash blue 4 times. Release the earbuds and close the case. Both earbuds can now be taken out at the same time. The lights will flash blue, followed by red and blue flashing on the right earbud which confirms they are paired. You can now search for your StreamBuds DX in your phone's list of Bluetooth devices. Only one entry will appear.
Check that both earbuds are fully charged. Place them in the charging case, close the lid and press the charge button on the case. Once the red lights on the earbuds have gone, they are fully charged. Check that both earbuds are powered on and linked together. Press the button on the earbud that is currently playing sound for three seconds. It will switch off. Then press and hold the button on both earbuds for three seconds. Their lights will flash for a few seconds while they link to each other. Once linked, one earbud will flash red and blue. You should now be able to pair it to your device and play music successfully.
It is possible to use each earbud individually in mono. First make sure both earbuds are in the charge case and remove all 'StreamBuds DX' entries from your Bluetooth device menu. Then remove the relevant earbud you wish to use. This will then appear on your Bluetooth device’s menu. You can then connect to this earbud.
