A:Answer Hello TW! The G733 LIGHTSPEED Wireless DTS Headphones:X v2.0 Gaming Headset USB dongle isn't something sold separately unfortunately, but I would try contacting Logitech's customer support, as sometimes they have access to a wider range of parts than what's available on their website: https://support.logi.com/hc/en-us/requests/new?ticket_form_id=360000621393&pID=b73d5a45-e7a6-11ea-a3ae-399727cfb703
