This is a wireless model. The only included accessory is the receiver; a microphone is not included. Purchased around November 2023. It was stored in its box for about a year, with periods of non-use. Non-genuine, but new, synthetic leather ear cups are available for an additional 400 yen. Operation has been confirmed, but please purchase this item as a junk item. Please refrain from purchasing if you are uncomfortable with used items.
