I'm guessing the case has a magnet that tells the headphones to turn off completely, instead of being in standby looking for a sensor to indicate you have put them on.
I agree though that the case doesn't seem like the best way to accomplish it. Put a switch on them, or allow them to fold in such a way that the folding/unfolding can power on the device.
