Wang Jinchi, vice secretary general of Shenzhen Electronic Chamber of Commerce, estimates there are 200 to 300 MP3 player manufacturers in Shenzhen. Some industry insiders say the number could be as big as 700 to 800 at the prime time of the industry.
Manufacturing MP3 players was highly profitable back in 2001, when an MP3 player could bring 200 to 300 yuan in profit for its producer. The profit dropped to 80 to 90 yuan in 2002 and 30 to 40 yuan in 2004 for most small-sized manufacturers.
