  • Publication number: 20160029114
    Abstract: The invention is about a real wireless earphone set including of two no-wire linking earphone assemblies. The earphone set communicates to an audio source with wireless protocol directly or through a wireless transmitter assembly plugged in the audio source. One of the earphone assemblies may be integrated with a microphone for two-way communicating. Users can check and set some parameters for each of the earphone assemblies by the control software of the earphone set installed and run in the compatible audio source. Since there is no audio wire between the two earphone assemblies, they can be wireless paired to the audio source separately, and the users can set for the right/left or mono channel of the earphone assemblies with the control software, the invention offers more convenience, safety and fluency for users that users can choice to use only one or two earphone assemblies depending on different situations.
