I recently struggled to find a cheap voice-over solution with reasonable quality… My editing software has a voice-over feature which can take sound input from the PC sound card; all sound cards or motherboards have a microphone input; so I just figured I should buy a quality headset with a built-in microphone. The microphone, being closest to the mouth, would bring a beautifully sounding voice while rejecting side noise. Or so I thought — the results were pathetic.
But there is a much better solution, at no additional cost.
