Abstract: An improved earphone which has stereophonic microphones and which is better suited for connection to such a multimedia device includes two ear units to be worn in or on the ear, which each include at least one sound generator and a microphone for binaural recording of ambient sound, a microphone unit which includes at least one further microphone, an operating unit which is connected via cable to the two ear units and the microphone unit, and a connection unit as interface, which is suitable for connecting the earphone to the multimedia device. For easy handling the earphone has at least two different function modes between which switching can take place both automatically and manually.

Abstract: A method of stereophonic recording is provided. A first audio signal is detected by a microphone in a first housing of an earphone detecting an environmental sound outside the first housing. A second audio signal is detected by a microphone in the second housing to detect environmental sound outside the second housing. The detected first and second audio signals are forwarded to an external device for further processing and recording via an output unit of the earphone unit. The first and second audio signals are processed and forwarded to the first and second electro-acoustic transducers in the first and second housing of the earphone respectively. The processed first and second audio signals are reproduced by the first and second electro-acoustic transducers respectively to implement a talk-through function.

Abstract: There is provided an audio and/or video transmission system. That audio and/or video transmission system has a microphone unit for detecting an audio signal. The microphone unit has a first wireless transmitting unit for wirelessly transmitting an audio signal by way of a first transmission path and a second wireless transmitting unit for wirelessly transmitting the audio signal by way of a second transmission path. The second wireless transmitting unit is adapted to embed a time stamp in the audio signal to be transmitted by way of the second transmission path.

Abstract: There is provided a microphone unit for recording audio signals comprising an audio processing unit for processing the recorded audio signals, a detection unit for detecting metadata belonging to the audio signal, and a first transmitting and receiving unit for transmitting the processed audio signal and the metadata.
