KnowBrainer Speech Recognition Perspective:


We like the Sennheiser SD Pro 1 (one speaker) and Pro 2 (two speakers) microphones for professional clients that want both the freedom of a wireless headset and the ability to switch between accurate PC dictation and crystal clear phone calls, with the push of a button. While testing the Pro 1 and Pro 2 we found the noise cancelling characteristics to be improved over their predecessors the DW Pro-1 and DW Pro-2 and also favor the look and functionality of the redesigned base/docking station. When compared to other similar microphones on the market the SD Pro 1 and Pro 2 are also notably easier to hook up, easier to operate and require no software.

Sennheiser Perspective:


Switch As You Please

Dual connectivity for both desk phone and softphone

Switch from one communication source to another with just a single touch on the base station. The SD Pro 2 is compatible with major global providers of telephony and unified communications platforms and solutions.
