The Voyager Pro UC comes with a USB adapter that is by default paired with the headset. You can plug the adapter into a PC or Mac and use the headset with a variety of softphone and VoIP applications that include options from Avaya, Cisco, IBM, Microsoft (OCS & Lync), ShoreTel, and Skype. The Voyager Pro UC is able to make use of the simultaneous connectivity of the phone and the PC. For example, if you're on a mobile call, the headset will communicate to the PC software and change your availability status to "On a call." Once you're done, the software will change it back to normal availability.
If you use Outlook, you can create a list of VIPs or favorite contacts that you communicate with frequently. You can set it up so that whenever you get an instant message or e-mail from one of these people, the headset will alert you, and then read out the subject line of the e-mail. In VoIP apps like Skype, you can also quickly switch from IM conversations to voice chat simply by putting on the headset.
As the Plantronics Voyager Pro UC has much the same noise-canceling technology as the Voyager Pro Plus, we're not surprised that the quality is equally as good. We paired the Plantronics Voyager Pro UC with the Apple iPhone 4, and quality was very impressive. Incoming voice quality was crisp, clear, and as natural-sounding as holding up the phone directly to the ear.
Callers reported similar results. They did report the occasional muddiness, but it wasn't a deal breaker. Calls were free of static and noise, and wind noise was reduced as well. Callers said our voice quality was clear and natural for the most part, even when we were in a noisy environment.
We're quite impressed by the audio quality of music as well. Sure, it's not a stereo listening experience, but songs had passable sound quality.
The Plantronics Voyager Pro UC has a rated battery life of 6 hours of talk time and five days of standby time.
