Yip & Lee's is an audio and MCU software design house in Hong Kong. Recently, we licensed Sound Retrieve Systems (SRS) and the latest audio technology :- FOCUS. We just finished a home audio and car audio enhancement product which has FOCUS and SRS 3D. Such units can elevate the sound from a low level speaker position to ear level to widen the "sweet position". Furthermore, the SRS 3D can generate surround sound to fill up space.
