## Long description

DEFENDER Cosmo Pro Wired Head-band headset delivers wired reliability and full-range sound for gaming, voice chat and multimedia playback. The circumaural, closed earcup design and soft protein foam pads provide passive noise isolation and comfortable long-session wear. A 2.1 m cable and 390 g weight give stable connection and a secure fit, while a flexible microphone and integrated volume and mic controls simplify in-game communication and quick level adjustments.
Advantages
The headset features a pulsing 7-color LED backlight with an on/off control, allowing visual customization or battery-free silence. A double headband design combines an external rigid frame for a close fit with an inner self-adjusting strip for comfort. Closed earcups and large over-ear pads reduce external noise and improve low-frequency response. On-cable volume control and a mic mute button provide immediate access to audio and microphone settings. The flexible boom microphone supports clear voice pickup for team chat and calls.
Suitable for
PC and console gaming sessions that require wired stability
Voice chat, streaming and multiplayer communication
Multimedia playback including movies and music
Use in noisy environments where passive noise isolation is needed

How to use
Connect the headset to the audio output of your PC, console or device using the wired cable. Position the headband on your head so the earcups fully enclose your ears and allow the inner self-adjusting band to seat comfortably. Adjust the flexible microphone close to your mouth for clear voice capture and use the mic mute button when you need to disable the microphone. Adjust playback volume with the on-cable control rather than changing system settings for quick level changes. Use the backlight on/off button to enable or disable the LED effect according to your preference or environment.
Usage recommendations
For longer sessions, periodically lift the headset and allow ears to breathe to reduce heat buildup. When using in shared or public spaces, mute the microphone when not speaking to avoid transmitting background noise. Clean the protein foam pads with a dry cloth and avoid exposing the cable to sharp bends to prolong service life.
