In the field of educational microphone applications, our company has over a decade of industry experience. To achieve the 'one teacher, one microphone' functionality, we have gone through a process from the initial simple close-range pairing design to the current system design concept. This journey reflects our in-depth understanding of the industry, knowledge of customer habits, and environments, as well as our continuous efforts to address customer pain points. This solution consists of an educational wireless microphone and a USB audio receiver, capable of local amplification, computer recording, and keyboard shortcut functions such as air mouse and page flipping.
