Italian brand Monitillo Marmi have released the “Ovo” marble iPhone amplifier. Made from a single piece of white carrera marble that has been carefully hollowed out to create the speaker, “Ovo” accommodates both the iPhone 6 and 5s. The non-electrical speaker system works via the item’s unique shape to project sound and responds to various listening modes depending on how the iPhone is placed. For direct sound the phone is positioned lying down, while having the phone sitting up creates a broadcast sound.
