Query: Sound was okay, but microphone is not stable

I needed a new microphone headset to talk to my team on Ventrilo with various games that we like to play. On Ventrilo the microphone is so crazy. Moving the microphone a little bit causes it to sometimes make it so my teammates can't hear me or I'll be too loud. After hearing complaints for the last couple days I'm going to go back and return it to get different headset.
