Do not confuse our new KnowBrainer modified "Hybrid Plantronics CS55" wireless headset microphone offering with standard Plantronics CS55 units sold by other vendors. Our new "Hybrid Plantronics CS55" not only handles standard telephone conversations like it's predecessor, but also doubles as the world's most accurate speech-recognition microphone we have ever tested. We have tested hundreds of microphones (headset, voice array and desktop models) with speech recognition software for over 14 years and we have never come across anything this accurate. Our previous favorite microphone was the wired KnowBrainer Sennheiser (modified ME3) headset microphone but independent, real world tests has raised the CS55 to the top.
The reason why we refer to this new microphone as “Hybrid” is because it includes a number of KnowBrainer proprietary modifications which include additional cabling and a specialized rocker switch that will allow you to seamlessly switch from wirelessly talking on the phone to wirelessly talking to your computer. Please do not ask about purchasing our rocker switch and/or modifications separately because this is proprietary information.

KnowBrainer Test Results
Accuracy Test Results
Sennheiser ME3 versus Hybrid Plantronics CS55
Test 1: ME3 = 96% CS55 = 98% (CS55 = 50% higher accuracy)
Test 2: ME3 = 97% CS55 = 98% (CS55 = 25% higher accuracy)
Test 3: ME3 = 98% CS55 = 99% (CS55 = 25% higher accuracy)
Test 4: ME3 = 99% CS55 =100% (CS55 = 25% higher accuracy)
We should further note that although we found the Hybrid Plantronics CS55 microphone to be exceptionally noise canceling (which included clapping playing loud music without producing an error). The Sennheiser ME3 scored a little higher on the noise rejection tests but you should have no problem using the CS55 in most work environments.
Endorsement from Daniel Costigan (Lieutenant Colonel, US Army-retired):
I cannot tell you how pleased I am with this headset. I am getting greater accuracy than I have ever gotten before. It types faster and quicker than anything I could imagine; the accuracy is right on target. I have never seen better results! I have never seen better speed! I have never seen that accuracy!
Endorsement from Thomas Coates, M.D. (Professor of Pediatrics & Pathology, Section Head of Hematology - LA, California):
After three days of using the Sennheiser MD 431 II microphone, I can really tell the difference between that microphone and the Plantronics CS55. Even though the MD431 is very good, the headset is strikingly better. Recognition speed is much faster and the accuracy is almost perfect.
