Hundreds of onlookers crowded around a booth inside the cavernous Las Vegas Convention Center , hoisting cameras overhead and straining for a glimpse of the woman with the tiny frame and the big fake eyelashes : . Snooki . The `` Jersey Shore '' star , more officially but less-well known as Nicole Polizzi , was at the International Consumer Electronics Show here Tuesday to promote a forthcoming line of headphones for iHip , a company that makes audio accessories . Less than 200 yards away , a similar throng jammed the SMS Audio booth , where hip-hop star 50 Cent was appearing on behalf of his own brand of headphones . And on Wednesday , pop singer Justin Bieber was scheduled to appear at a CES event for TOSY , a robotics company that 's unveiling an `` entertainment robot . '' These celebrity endorsements can certainly make headlines at CES ( witness this article ) . But will they translate into sales ? In recent years , celebs have a mixed track record when it comes to launching tech gadgets . Musician Dr. Dre has had success with Beats , his popular line of high-performance headphones . But singer Lady Gaga showed up at last year 's CES to unveil a prototype of camera-equipped Polaroid sunglasses that never reached the market . `` They definitely help attract people to the booth . You see people all crowding around the booth , and they 're not looking at the new Bluetooth headset or whatever , they 're taking pictures of the celebrity , '' said gadget analyst Andrew Eisner of Retrevo , the consumer-electronics site . `` It 's Vegas -- it 's showtime . But whether it carries any weight ( beyond CES ) , I do n't know . '' A celebrity tech endorsement makes the most sense , Eisner said , if the person has some expertise about the product -- witness all the musical artists ( Ludacris also is at CES , as he was last year , with a line of headphones ) creating signature audio equipment . That 's something 50 Cent understands . `` It actually speaks to what I do for a living -- making music , '' he told CNN in reference to his headphone venture . His product line , the wireless Sync by 50 ( $ 399 ) and the wired Street by 50 ( $ 299 ) , hit the market last month . The rapper also understands that some star wattage can bring attention to a gadget that might otherwise get lost in the sea of gadgets here . `` CES is exciting , '' he said . `` But so many amazing things do n't have proper marketing in place yet , so people wo n't get a chance to see them . '' Back at the iHip booth , Snooki sat at a table and smiled patiently while fans lined up for autographs and photos . She wore a leopard-print top , a short skirt and five-inch heels , and fiddled with her white iPhone between visitors . Sometimes , she sang along to the dance music being spun by the event 's DJ . Snooki was not available for interviews . But iHip spokeswoman Amanda Breault said the company approached the reality TV star to help build buzz around its products . `` We built the line around the things that she likes , like animal prints and bling . She designed everything to fit her attitude and her fashion sense , '' Breault said . `` We knew that by having her , we could instantly attract fans , sponsors , press . The response has been tremendous . ''
