Soundsport Free Battery in case draining

This problem has been on going since I got my Soundsport Free In-ear headphones.  When I leave the earbuds in the case for an extended period of time (3-5 days), the battery drains.  Not only does it drian the case batteries but also directly from the earbuds them selves too.  So when I go to use them they are dead and I have to plug them in again.  I have consistantly updated the firmware and sitll have the issue.
