I just had to have the system box replaced on my Makro Racer 2. Th e old box had the removable dongle for pairing with the Makro white edition wireless headphones. The new system box does not have a removable dongle so I am assuming the wireless capability is built internally. Can I use my original white edition headphones with this new setup or do I need to purchase the Makro green edition headphones? Also what would be the pairing procedure? Any help would be appreciated.
