For wireless operation, insert the BT700 dongle into a computer USB port and pair the headset via Bluetooth; alternatively, pair directly with a mobile device through Bluetooth settings. Adjust the headband and ear cups for a comfortable fit and place the microphone boom or位置 (if applicable) near the mouth for optimal voice pickup. Charge the headset according to the manufacturer's instructions before initial wireless use.

Recommendations

Use the wired USB-A connection when maximum call stability or full compatibility with a desktop PC is required. Use the BT700 dongle for instant plug-and-play wireless connectivity in shared or secured IT environments. For extended wear, periodically reposition the ear cups and use adjustable headband tension to reduce pressure. Keep firmware and Teams client updated to maintain certification compatibility and audio performance.
