Earphone Jack

Earphone Jack is a Quirk used by Kyouka Jirou.

Description
Earphone Jack allows the user to raise the sound of her own heartbeat to high levels by connecting them to holes in her boots, but also catch very faint sounds with her plugs.

Earphone Jack allows the user to plug the jacks that hang from the user's earlobes into all sorts of things and channel the sound of her heartbeat into them; the vibrations cause havoc inside the objects.

Earphone Jack also allows the user to catch sounds, giving the user the ability to hear across even extremely thick walls.

Earphone Jack is versatile; it can stretch up to 6 meters and the sound radius is approximately 12 meters.
