Bests & Worsts Reviews from Amazon

I read lots of reviews for the many usb/computer speakerphones and narrowed down to three. There were so many conflicting reviews it was hard to choose! I just wanted THE best one that works well. I ended up ordering and testing these three: - Polycom CX100 - Jabra 410 - Plantronics Calisto P420 I then hooked all three up to my computer...place a skype call to someone in another room in our office and one by one switched the audio devices in skype. Polycom devices didn't have enough volume and had more background noise. Plantronics device was overall good, loud and clear..though the buttons were a bit confusing for volume and other controls not so intuitive (overall better than polycom device) The Jabra was mine and other office mates pick for best one. It was very loud, audio was clear eliminating background sounds and has cool intuitive controls. Aside from the audio quality I like the touch buttons for controls that are sensitive and the lights that change on the device to show status. Overall this is the one I kept and would recommend it to anyone over the others I tested.
