Anker PowerConf S3 - Background Noise

Hi all,

Just got a PowerConf S3, seems to work well, speaker is loud, microphone picks up my voice fine… however, it’s also picking up a lot of background noise, i.e. paper rustling, chair squeeking, etc. My Polycom speakerphone isn’t as sensitive, is there a way to reduce the microphone sensitivty on the Anker or have a way of filtering out the background sound?
