Sirensong Silencer

Wondrous item, uncommon

You can don and doff this golden ear cuff on a willing Medium or smaller creature using an action. While wearing the cuff, the creature has advantage on any saving throws against being charmed. In addition, tapping the ear cuff twice deafens you, although you can still faintly hear the sound of the ocean (no action required). Tapping the cuff twice again allows you to hear normally once more.

"That mournful note across the sea, her honeyed words that bound,

Upon the rocks my crewmen wept, once I had heard her sound."
