i.VoicePRO 901, a Bluetooth headset equipped with dual microphones and noise-filtering software to let users hear and be heard clearly. The idea is to kill most of the ambient noise for crystal-clear phone calls even in noisiest of the environments.
The first mic is notched and U-shaped, sitting on the cheek side of the headset and directing the user’s voice directly into it. On the other hand, a second microphone is placed on the side, facing away from the user and targeting ambient noise.
All of the standard handset features are present, including voice-dialing (if your mobile phone supports the option), redialing of the last-number redial, call rejection, call transfer, auto re-link, and mute. In addition, there are dedicated buttons for adjusting volume
