Headphones Can't Charge

1. Turn the tower off, then turn it back on and see if the green "CHARGE" indicator on the tower lights up. (Starting from Batch T23F1, the red "CHARGE" indicator on the tower will light up for 1 second)
2. Check whether the headphones' or tower's charging pins are rusted. -- Clean them with a clean cloth using 75% alcohol. Wait for them to dry, then try charging again and see if it works.
   
3. Check the batteries
   1. Open the battery cover and roll the battery back and forth with your fingers to make sure the batteries have good contact with the poles.
   2. If you need new batteries, purchase new batteries at this link - https://avantree.com/battery-for-ht280. Only the ORIGINAL GREEN AVANTREE Batteries will work. If you use different AAA batteries, they WILL NOT Charge. 
      

Note: It's suggested to check the charging LED on the transmitter tower/charging dock. The LED on the tower will tell you whether the headphones are charging or not. It will be GREEN if it's charging, and off if it's fully charged (Starting from Batch T23F1, it will be RED while charging, and turn solid GREEN when charging is complete). The headphones' LED will only light up if you charge them while still powered on, and only for 5 minutes.
