Beats Electronics is a division of Apple which produces audio products. Headquartered in Culver City, California, U.S. the company was co-founded by rapper and hip hop producer Dr. Dre and Interscope Geffen A&M Records chairman Jimmy Iovine. The subsidiary's product line is primarily focused on headphones and speakers. Beats' original product line was manufactured in partnership with the AV equipment company Monster Cable Products; following the end of its contract with the company, Beats took further development of its products in-house. In 2014, the company expanded into the online music market with the launch of its subscription-based streaming service Beats Music service.
