IC-BK06

I've had it for a few months. Usually, when I open it, a light turns on right away. Then I'm able to connect easily by bluetooth.

Today, when I open it - no light. Won't connect.

I recently charged it, and usually the charge lasts me 4 months.

Today, when  I plug it in to charge, no light turns on like it usually do.

Seems like it has died.

Any help would be appreciated.
