Yesterday, Dr. Dre and Jimmy Iovine, Chairman of Interscope Geffen A&M Records, joined forces with Monster Cable Products to design "Beats by Dr. Dre" high performance headphones.

The headphones, which utilize newly developed driver technology, were conceived by Dr. Dre and mutually designed with Jimmy Iovine and Monster's sound engineers over the past two years. The high performance "Beats" headphones were designed to accurately replicate various frequencies, including low end bass, while maintaining a natural sound. Monster Cable also hosted a number of other events at the CES, including a concert featuring Mary J. Blige.

Monster Cable was founded by Noel Lee in '79 and has become the world's leading manufacturer of high performance cables. In addition to cables, the company also manufactures other products for mobile devices, amplifiers, computers, as well as home theater and audio.The "Beats by Dr. Dre" headphones will hit stores this spring with a retail price of $399.99 dollars.

Manaj, Dre’s daughter also made an appearance at the show where the announcement was made, to promote the online video and card game Street Cred from TM Media Group. At age 23, she is also the first hip-hop artist signed to TM Media’s new hip-hop imprint and plans to release a DVD titled Daddy’s Shadow.

According to reports, the DVD is based on her attempt to "break into the music industry despite her legendary multi-millionaire father’s objections and lack of support."
