Kleer Semiconductor supplies its wireless earphone technology to Germany’s Sennheiser, a major manufacturer of high-end audio products. Based in California but retaining most of its operations in Ottawa where it was founded in 2002, Kleer says its technology has been integrated into Sennheiser’s new MX W1 wireless stereo earphones. “The name Sennheiser has been synonymous with top-quality audio products for over 60 years,” said Kleer CEO Levent Gun. “It’s therefore a huge vote of confidence that this industry giant has validated our wireless audio technology with an outstanding product that we believe will set a new standard in wireless audio sound.” Kleer’s Listen In technology enables high-quality stereo sound from any Kleer-based portable media player, while using significantly less battery power than competitors’ products, according to the company. It also allows two or more people, each with a set of earphones, to listen simultaneously to the same audio stream.
