My Tzumi Headphones won't turn on!

My Tzumi bluetooth over-ear headphones suddenly won't turn on. Yesterday, they worked perfectly fine, like they always did. When I got home and wanted to use them, the light wouldn't flash or turn on, and they won't connect.

I don't get it, but this morning they're suddenly working again! But it says "Need charging" when I've been charging it day and night.
