I am selling it because I no longer have a use for it. I believe it is a 3.5mm plug, but I am not certain, so there is a possibility I am mistaken. It is the size of an earphone jack. I connected it to the earphone jack of my smartphone and the jack of my speakers, and music played. Operation has been confirmed. Please check the condition in the images.
