Harvey went out on tour with Linkin Park to get back in contact with touring musicians and while on tour he noticed the popularity of iPods and other mp3 players. He returned with the idea that Ultimate Ears should offer a consumer model for audiophile listeners. The resulting UE-5c appeared in January 2004 sold for $550. High sales of these doubled the company's income. Pursuing this direction further required outside investment, and the Harveys contacted Bob Allison, owner and CEO of Innovate Partners, an investment holding company in Irvine, California. Allison became the CEO of Ultimate Ears as the company moved to Irvine, with Mindy Harvey the president and Jerry Harvey the CTO. Innovate Partners helped Ultimate Ears develop a manufacturing source in China to provide the expected volume of sales. By April 2005, the resulting Super.fi 5 Pro, a double armature product, was offered to consumers at $250 per pair, and sales of these helped Ultimate Ears to gross more than $10 million in 2006. That same year, Ultimate Ears teamed with M-Audio and with Altec Lansing to produce rebranded lines of earpieces, one sold under the management of M-Audio (their IE model line) and the other under the Altec Lansing name.
