How to use

Connect the Poly 3320 to a computer or other USB-A equipped device for immediate plug-and-play operation. Position the headband so the earcups sit comfortably over the ears and adjust the microphone boom toward the mouth for clear voice capture. Use the device within the supported frequency range for calls and multimedia. For models with a 3.5 mm connector, plug into mobile devices or tablets as needed.

Recommendations

For best call clarity, position the microphone approximately 1–2 cm from the corner of your mouth and keep it pointed toward your mouth but out of the direct airflow. Store the headset in its pouch when not in use to protect ear cushions and the boom from wear.
