This is an adapter that splits a 3.5mm mini-plug headphone, etc., into two. It has been stored for a long time. The contact points have been cleaned with anhydrous ethanol, but if the connection is poor, please try a contact restorer. ● No comment is needed before purchase; direct purchase is welcome. ● It will be shipped via Yu-Packet Post Mini from Yu-Yu Mercari. ● Due to work, I may not be able to return home for 2-3 days, so shipping may be delayed by a few days depending on when you purchase. I will notify you via message if there is a delay in shipping, so please understand. #Sony
