Kamen Rider 555: Hyper Battle Video (仮面ライダー５５５（ファイズ） ハイパーバトルビデオ Kamen Raidā Faizu Haipā Batoru Bideo) features a boom box called the SB-555A Faiz Sounder developed by the Smart Brain corporation appearing at the laundromat where Takumi, Mari, and Keitaro work at, causing them and everyone else to break into song and dance. The Faiz Sounder was created as a result of a contest for Televi Magazine for a new weapon for Kamen Rider Faiz.
