Woojer Series 3 devices offer Bluetooth connectivity with both a source device (like your PC or mobile device), and can also connect to Bluetooth audio peripherals (like your Bluetooth headphones or Bluetooth speakers) directly without the need for any additional equipment.
However, several Bluetooth peripherals, e.g.: specific AirPods models, have been reported to have some connectivity issues with Woojer. We've already addressed this issue and our next firmware update will solve this problem.
