In any case, you can double this cable the audio signal from a source with standard phone jack (z. B. PC, TV, phone, etc.) and thus to output the sound at the other end on two different devices. It can be connected to only one audio output so say for example two sets of headphones. Compared to other splitter cables is an advantage of this model is that it has very slim plug housing and therefore not comes so clunky. Those who place even with a small part as this particular emphasis on optics and concretely a white version examined (which you do not find very often in Splitter cables), here is therefore very well served.
