The Reasons Why JBL TUNE 120TWS Left Earbud not Working

Reason 1:

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:
