Anna and Sophie procured a new larger headset that will be able to accommodate the dome more easily. The new headset is made for phones that are up to 6.5” diagonally, which is much bigger than the previous headset. Anna hollowed out the headset and performed the needed measurements in order to position the dome...... KEEP READING
