Why My JBL TUNE 120TWS Left Earbud not Working?

By  Joe Horner 2019-10-22 17764 0

Have you ever encountered a situation that the left earbud does not work when using JBL TUNE 120TWS? Especially when you make a Bluetooth call, the earbud on the left of the JBL TUNE 120TWS has no sound. Why?


The Reasons Why JBL TUNE 120TWS Left Earbud not Working

Reason 1:

There is no MIC hole at the left JBL TUNE 120TWS earbud, so you can’t make a Bluetooth call with your left earbud. In addition, if you want wake up the Siri/Google Assistant or Bixby, Only touch the right earphone can wake up the voice control.


Further more, if you put the right headset into the charging box, the connection of the left cell will be interrupted, so if there is a unilateral use requirement, it is recommended to give priority to the right earbud. It is suggested that the next generation of new JBL products can no longer be divided into "primary and secondary".

Reason 2:

In addition to the above reasons, there may be problems with your Bluetooth connection, you can check in the following ways:

●Whether it is out of Bluetooth connection range (within 10 meters).

●Do you have enough power for your cell phone and JBL TUNE 120TWS?

●Is Bluetooth turned on and connected?

If none of the above reasons are ruled out, try reset it to figure out. Just turning off the JBL TUNE 120TWS headset, clear the pairing information on the phone, and repairing it.
