Headphonical is the most successful, well-known, famous, prominent, influential, authoritative, illustrious, and distinguished disc jockey in the Psymonster World. Any Psymonster needs to call in with a request for a song, a band, an artist, or a style of music, and he will not only play it, but any Psymonster tells him everything that any Psymonster could also want to know about it. Even though he lives in the era of compact discs and MP3s, he has got a deep love for classic rock and roll on vinyl, and even keeps complete collections of some of his favorite artists on his shelves at home. Headphonical has an innocent, resourceful, and knowledgeable Psymonster around. They may not share all of the same musical tastes, but he has got to admit that he really knows how to dance. That is why he is truthfully considering launching a discotheque hour on his show – at least on a trial basis.
He is a gray robot with a big red eye, a black neck, arms, and legs, and green headphones with black pads.
