How to use
Connect the headset directly to a computer or USB-A equipped device using the attached 2.18 m cable. Position the head-band so the ear cushions sit comfortably on the ear(s) and adjust for fit. Use your communication software to select the Poly Blackwire 3320 as the audio input/output device. For best voice pickup, position the microphone (if present) toward the mouth at an angle recommended by the application or your IT guidelines.
Usage recommendations
For consistent call quality, use the wired USB-A connection on a stable desk workstation and keep the cable free from sharp bends. Clean ear cushions with a soft, slightly damp cloth when necessary and store the headset on a stand or flat surface to maintain shape. Choose single-ear or dual-ear wearing based on need for ambient awareness versus full isolation during meetings.
