How to use

Connect the headset to a compatible device using the 3.5 mm jack for phones or tablets, or plug the supplied USB-A adapter into a computer USB port for plug-and-play use with most desktops and laptops. Adjust the head-band and ear pads for a secure, comfortable fit so the microphone sits close to the mouth for optimal speech pickup. Use the host device’s audio settings or unified communications client to select the headset as the input and output device and adjust levels as needed.

Recommendations

For best speech clarity, place the microphone 1–2 cm from the corner of the mouth and avoid covering the microphone with clothing. Keep the 3.5 mm connector or USB-A adapter free of dust and debris, and store the headset in a dry place when not in use. If you move between devices frequently, use the USB-A adapter for PC connections and the 3.5 mm jack for mobile devices to maintain compatibility.
