This is a genuine SONY mono headset. Unused. Included with PlayStation 4 (official product). It has a microphone function, so voice chat is possible. You can use it immediately by plugging it into the earphone jack on the PS4 official controller♪ As it is a PlayStation 4 official product, it is easy to use and recommended♪ I've also used it for voice chat in Fortnite on the Nintendo Switch. I have multiple units, so bulk purchases are welcome. I have a lot of items for sale, so please take a look at my other listings. Shipping costs may be reduced with combined purchases and combined shipping☆ Many rare and one-of-a-kind items are available, and they will be gone when they're gone. It will be shipped in simple packaging. Thank you.
