PROBLEM 1: LACK OF BATTERY LIFE 

PLAY TIMETWE HAVE ONLY 2-5HOURS

PROBLEM 2: CHARGING 

CAN NOT USE EARBUDS WHILE CHARGING

SOLUTION

 

EXTENDED BATTERY + DOCKING CLIP

 

The extended Battery cable provides extra 4-5 hours of play time, and the exclusive docking clip systems bring several benefits for users. Unlike most true wireless earbuds including Apple Airpods that can’t be used when charging, this extended battery cable allows users to continue listening or calling while being charged. The Pogo pins in the docking clips deliver electrical power from the extended battery to the earbuds. In addition, the magnets on the clips of the extended battery cable allow functionality in which they can be connected, while still hanging on the user’s neck when it is not being used.
