The millions that Simon Cowell makes from shows like X Factor, American Idol and his 'Got Talent' series obviously aren't enough, as the music mogul has just released a line of top-of-the range headphones, branded X Headphones, in a joint venture with Sony.

Cowell said his headphones would be the best on the market, saying they were "like being in the recording studio when the records are made. The sound is that clear". (All photos AAP)
