Abstract

There are proposed wireless headphones which have at least one electroacoustic transducer for the reproduction of audio signals, a receiver for receiving wirelessly transmitted audio data, an intermediate memory for putting the received audio data into intermediate storage, an audio decoding unit and a control unit. The audio data wirelessly received by the receiver are firstly buffered or put into intermediate storage in the intermediate memory. The control unit controls reading of the compressed audio data stored in the intermediate memory so that said data are passed to the audio decoding unit where the compressed audio data are decoded and then outputted by means of the electroacoustic transducers. Wireless transmission is effected at a higher speed than the reproduction of the stored audio signals.
