If one of the earbuds is connected but has no sound, please make sure it IS connected: you should hear "Connected" from the earbud during the pairing process (kindly go to STEP 2).
If the earbud cannot turn on, please check another section "One earbud doesn`t charge or turn on".
If one of the earbuds doesn`t say "Connected", please check another section "One earbud cannot connect".
Note 1: While talking on the phone via TREBLAB X2, only the main unit (the right one) produces sound.
Note 2: When using left earbud separately, some remote controls (answer/reject call, volume up/down, etc.) will not be available.
Kindly reset your earbuds by the following steps:
- Ensure that your TREBLAB X2 are fully charged.
- Go to ALL your devices the earbuds were ever paired with and delete TREBLAB X2 from the lists by clicking "Forget this device" in Bluetooth menus.
- Power the device off and on. TREBLAB X2 earbuds will be deleted.
- Take TREBLAB X2 off the charging dock and turn them ON.
- Press and hold both buttons (POWER and MODE) on each earbud for 5 seconds to restore the factory settings. (You will hear the “beep” sound once and then twice again. LED indicators should start flashing.)
- Power OFF the earbuds, then turn back ON, and follow instructions for pairing with one device only:
1. Press and hold the POWER button on the right earbud. You will hear the "Power ON" voice prompt, and "Pairing" a few seconds later (LED will flash red and blue rapidly). Release your finger.
2. Activate Bluetooth on the device, scan/search for TREBLAB X2, and click CONNECT.
3. You will hear "Connected" from the right earbud. (LED indicator will flash blue every 7 seconds).
4. Press and hold the POWER button on the left earbud until you hear the "POWER ON" voice prompt in the left earbud. Release your finger.
5. Wait for 5-10 sec., and the left earbud will automatically connect to the right earbud.
6. You will hear "Connected" from the left earbud after connecting (LED indicators on both earbuds will flash blue every 7 seconds).
