"Smarphone prices have been falling. HTC will have to differentiate itself by adding value in content or services," said Richard Ko, an analyst with KGI Securities. He expected more deals will be on the way for HTC. Beats Electronics, which makes high-end headphones and speakers, was founded by Jimmy Iovene and Dr Dre, a U.S. rapper and music producer.HTC expects the deal to close in coming months and expects to have a number of products that incorporate Beats technology on the market by the end of the year, said Jason Mackenzie, Beats Electronics' president for global sales and marketing. Iovene, chairman and founder of Beats Electronics, will continue to run the company. He is also chairman of Interscope Records, which produced albums such as Bruce Springsteen's "Born to Run." At midday trading, shares of HTC had slipped 2.6 percent, trailing the main index's 0.69 percent loss.
