Red Hair Pieces (?)
Sonic Cry was an attack performed by Super Sailor Moon in the video games Sailor Moon S: Jougai Rantou!? Shuyaku Soudatsusen and its sequel Sailor Moon SuperS: Zenin Sanka!! Shuyaku Soudatsusen. The attack was similar to Supersonic Waves.
Super Sailor Moon creates sonic waves that come from her head, presumably from her jewels, and attacks the enemy nearby or from above.
