A headphone for digital signal assembly comprising:
- a pair of right and left ear pieces, each ear piece comprising a housing including an electroacoustic transducer having a diaphragm and a plurality of voice coils fixed to the diaphragm;
- only one signal processing circuit, wherein the only one signal processing circuit is in only one of the right and left ear pieces;
- a longitudinally curved head band having the right and left ear pieces at its ends;
- and
- cables respectively connected to the voice coils,
- wherein the respective cables consist of a positive input line and a negative input line,
- wherein each positive input line and each negative input line connected to a same voice coil form a stranded pair,
- wherein the cables are disposed inside or along the head band, and
- wherein the cables are configured to transmit digital signals
- i) from the only one signal processing circuit in one ear piece
- ii) to the electroacoustic transducer in the other ear piece.
