Unable to pair replacement dongle to a barracuda x gen 1

Hi I have an old barracuda x headset (Headset 1) that is no longer in usable condition but i have a new one but I've lost the dongle for it (Headset 2), I've been trying to repair the dongle from headset one to headset 2 but the pairing utility wont pair the headset.
is there a specific version of the pairing utility that works for the gen 1 barracuda x headsets

Kind Regards Eddisson
