What to do if EAH-A1000 is not charging.

  1. Check the USB-C cable and make sure it is firmly connected to the headphones.
  2. Check the USB cable ends and the headphone charging/audio input terminal for dirt or foreign material.
  3. Make sure the other end of the USB-C cable is firmly connected to a powered computer or a USB PD-compatible AC adapter.
  4. Confirm that the connected power source is supplying power.
  5. If charging from a computer, make sure the computer is turned on and is not in standby or sleep mode.
  6. Use only the supplied USB Type-C cable included with EAH-A1000 to charge the headphones.
  7. If charging does not begin, disconnect the USB type-C cable and reconnect it securely.
  8. Try another USB Type-C port if necessary.
  9. If the headphones have not been used for a long time, the charging LED may take several minutes to illuminate.
  10. If charging and operating times have become significantly shorter, the internal batteries may be exhausted. The manual states that each internal battery can be recharged approximately 500 times
