※Note: I have requested the manufacturer to deactivate the activation since late last fall, but they have not responded. Also, I do not have the receipt from the purchase, so I cannot use the dedicated plugin. Therefore, I am selling it at a lower price than the market value. You can use the headphone functions normally even without using the plugin. I have used it for about six months since the purchase, so there is a slight feeling of use. The original box and cable are included. Please purchase with the above in mind.
