Bardic Buds of Listening

wondrous item, common

These small objects resemble teeth which are blue in color. They fit comfortably in the ears of any small or medium creature. While equipped, you can use a bonus action to think of a non-magical song that you know. The buds will begin playing the song. While playing, you have disadvantage on any sound based perception checks.

Creatures within 10 ft of you may make a DC 15 perception (sound) check to hear the music. If they fail, the music is too quiet for them to notice.
