This is an earphone jack adapter that converts to an aircraft's dual jack. It came with PHIATON earphones and is a great item that allows you to fold the jack part and store it compactly in the main body. I think it's a very rare item that was difficult to obtain back then. Please consider it at this opportunity. I am selling a set of 2. ・One has no noticeable scratches and is clean. ・One has some scratches. Please check the specifications and condition in the photos. The condition is good, but please refrain from bidding if you are extremely sensitive to the appearance. As this is a personal sale, returns and support are not accepted. Please bid with the understanding of the above. ■ I am also selling it elsewhere. Please understand if it sells out due to timing.
