Insert the plastic opening tool in the crack in between the cover and the rubber spine with the power button.

Pry off the cover, beginning with the side without the volume and bluetooth buttons.

When prying the cover off, the six clips (three along each side of rubber spine) that attach the cover to the speaker will make snapping sounds.

Watch out not to damage the clips on the buttons' side, pry open with caution.

Pull the cover off with your thumbs.
