Noise Filtering: 7
KnowBrainer Exclusive - Includes Dragon Set-up Guide
You have hundreds of excellent Bluetooth microphone choices for cell phone use but speech recognition has much higher demands. Until recently, only the VXi VoxStar UC Bluetooth microphone met our requirements but because of the long boom, the VoxStar is not very popular among cell phone users. The Sennheiser Presence UC changes that perception. The Sennheiser Presence UC is the only non-extended boom Bluetooth microphone we have found to deliver 99% accuracy in NaturallySpeaking. If you are looking for the perfect low-profile combination cell phone/speech recognition Bluetooth microphone this is it. However, if you are working in a noisy environment, the VoxStar UC would be a better choice.
