The two headsets are single - ear and come with 4 - pin female XLR connectors. This set includes the correct power supply and antennas. However, be aware that one unit's power supply is missing, the button cover on one remote beltpack is gone but the button still works, and the muffs on the headsets are wearing out.

Using this Eartec STX1000 set is easy. First, connect the headsets to the beltpack using the 4 - pin female XLR connectors. Then, power on the units with the available power supply. When using the remote controls, you can operate the system conveniently. As for the missing power supply, you may need to find a suitable replacement. When the button cover on the remote beltpack is missing, handle it gently to ensure the button keeps working. Since the muffs on the headsets are deteriorating, you can consider replacing them to improve comfort. Keep the units away from water and extreme temperatures to maintain their performance. Regularly check the connections to make sure everything is working properly.
