How to use
Fit the head-band so the on-ear earpad sits comfortably over one ear and position the boom arm near the mouth; the boom arm can be folded away into the headband when not in use. Connect the headset to your device using the appropriate connector (3.5 mm jack or USB-A/USB-C) and allow the system to recognize the device for immediate plug-and-play operation. For Microsoft Teams certified variants, use the dedicated Teams button to access app functions as configured by your system administrator.
Usage recommendations
For optimal voice clarity, position the boom arm close to the corner of your mouth but avoid contact with lips. Use the headset in a quiet workspace or combine with local noise control measures for improved call quality. Store the headset in its carry pouch and fold the ear cup flat when transporting to protect the earpads and boom arm.
