After vocalist ANZA left the Sailor Moon musicals in 1998, she tried a solo career for almost two years, receiving help from the guitarist Hiro and met his brother Mar. In that time she was asked if she wanted to be in a different kind of band and eventually agreed.

Together they formed the band Deep Blue. They found bassist Kawady and drummer Okaji managing to release their first single, Escapism in 2000 after changing the name to Head Phones President.Before the band's second single Crap Head, bassist Kawady decided to leave and was replaced by Narumi.

Playing at small venues all over Japan, they started to gain more popularity. In 2002, Head Phones President made their first international tour, including a stop in New York City.Head Phones President's first album Vary was released in late 2003, after which the band returned to America for another short tour and started releasing CDs in the United States.

In 2005 Okaji left the band, desiring to make his own music. They recruited a support drummer Batch, who was made an official member in 2009. They continued to tour Japan, taking intermittent breaks, allowing Anza to work on her solo career.

The end of 2006 saw the release of their first live DVD, Toy's Box in August. The band desired still to tour Europe, and in February 2007, they went to Sweden for two performances.In November, they performed at the animation convention Pacific Media Expo in Los Angeles, California.
