The scoop: Voyager Focus UC, by Plantronics, about $300.
What is it? This system comes with a headset, charging dock, Bluetooth USB dongle (for connecting to a PC or Mac) and carrying case. The headset lets users connect to two different Bluetooth devices (such as a computer and mobile phone, or a mobile phone and tablet), switching them automatically between those audio sources when a call comes in. On the PC side, this means using the dongle to connect to “softphone” apps such as Skype, Lync, FaceTime, etc., or music services like Spotify or Pandora. The headset also includes an Active Noise Cancellation feature, so if you’re annoyed by the sounds of your co-workers, you can flip the switch and pretend that you’re on an airplane.
