@leon47253 you are not telling us where you are connectingyour headset to. If you are using this headset on a Windows computer try the solution listed by Microsoft:
1. Run Device Manager[br]
2. Go to the area that lists your headset (probably "Sound, video and game controllers")[br]
3. Right click your headset and select "Properties"[br]
4. Go to the "Drivers" tab[br]
5. Click "Roll back driver"[br]
[br]
If "Roll back driver" is greyed out, do the following:[br]
[br]
1. Right click your headset and select "Update Driver Software..."[br]
2. Select "Browse my computer for driver software"[br]
3. Select "USB Audio Device" from the list
Of course, you also want to check in Preferences that the mic level is turned up.
