These plain hoops can be made of any of the magical materials, and come in pairs. When a single mote is committed to each (not necessarily by the person wearing the earring), the wearer of one earring can clearly hear anything the wearer of its twin says, no matter how quietly. The earrings have a range of up to 5 miles.
