I just purchased a Logitech USB Headset H390 and am attempting to use it with Windows 8. My computer detects the headset no problem, and I can hear sound through it without any difficulty. However, the microphone doesn't pick up my voice unless I press it into my mouth, until it's almost touching. As this then pulls the earpiece off my ear, it's not really a sustainable way to use the headset.
I've tried using all my computer's USB ports, and it's the same on each one. I've tried adjusting the volume and toggling the mute button on the headset itself. I've also tried changing all the microphone settings I could find on my computer, but to no avail.
If anyone has any ideas about increasing the range that the microphone picks up, I would appreciate it. Thanks!
