Advantages

Suitable for
Professional video conferencing and online meetings
Daily office work and call center operations
Listening to music and media playback
Home office setups requiring reliable voice communication
This headset may not be suitable for users requiring high-end audiophile-grade sound reproduction for professional music production. Additionally, the supraaural design may not provide the same level of passive noise isolation as over-ear models in extremely loud environments.

How to use
To use the headset wirelessly, pair it with your Bluetooth-enabled device via the standard settings menu. If your computer lacks Bluetooth, insert the included USB audio adapter into an available port for automatic plug-and-play pairing. You can adjust the boom microphone up to 270 degrees to achieve the optimal position for your voice. Use the integrated mute button on the microphone to quickly silence your audio during calls. The headband can be adjusted to fit your head size for a secure and comfortable fit.
What to consider before purchase
Ensure your device supports Bluetooth or has an available USB port for the included adapter
Consider the supraaural fit if you prefer ear cups that rest on the ears rather than enclosing them
Verify that the 3.5 mm wired connection is compatible with your specific audio equipment
Usage recommendations: For optimal battery longevity, ensure the headset is fully charged before initial use. Keep the microphone positioned close to your mouth for the best noise-cancelling performance during calls.
