How to use

Connect the Blackwire 5220 to a compatible device using the appropriate wired connector. Position the head-band over your head and adjust until the supra-aural ear cushions rest comfortably over your ears. Place the microphone boom so it sits close to your mouth but out of the direct airflow to reduce breath noise. Adjust volume and device audio settings as needed. Use the headset for voice calls, video meetings or music playback as required.

Recommendations

For best voice clarity, position the microphone 1–2 cm from the corner of your mouth and avoid covering the microphone with clothing. When not in use, store the headset in a dry place away from extreme temperatures. If you experience fit discomfort, re-adjust the head-band and ear cushions to achieve a balanced pressure and ensure prolonged comfort.
