    • The speaker housing may require more force than expected to remove because it is held together by a thin black rubber adhesive. Do not be afraid of using more force if you are unable to remove it on the first try.

    • When the housing is removed the rubber adhesive will come off. This should not effect your device's functionality in any way.

    • Grab the outside of one speaker housing and pull outwards (starting with the top) while holding the main casing still with your other hand.
