The level of comfort is a boon, but sound quality is what makes the Plantronics Voyager PRO worth its asking price. It's far better than most budget or mid-range models, with a beefy bottom end that's far removed from the reedy sound we've heard from some lesser headsets.
In use out and about, this product's advanced features come to the fore. In addition to the microphone that's responsible for recording your voice, the Voyager PRO is equipped with two extra microphones that sense ambient noise and eliminate it using advanced noise cancellation. The signal is processed at both ends too, improving quality for both the caller and the person on the other end of the line. Without being able to be in two places at the same time, like Marty McFly from the Back to the Future movies, we can only comment reliably on the caller's experience, but here the Plantronics Voyager Pro succeeded completely. Calls came through loud and clear even on a noisy commuter train.
We tested the headset with a variety of devices, including the Android-powered HTC Legend, the Windows Phone 7 LG Optimus 7 and Apple's iPod Touch. The Bluetooth connection with the HTC Legend was unreliable, prone to failing whenever there was much movement, but we'll attribute this to the phone rather than the Voyager Pro as it was faultless with the other devices. The range is excellent too, with the signal remaining clear for more than 15m, and a simultaneous connection with a phone and PC is possible.
It has no problems streaming audio other than calls too, and while the single-speaker earpiece isn't all that satisfying when listening to music, it's perfect for speech-based radio, audiobooks and podcasts. Any media playing is stopped when your phone gets a call too, obviously - and picks up again afterwards.
The Plantronics Voyager PRO can also sense whether it's on your ear or not. Put the earpiece in while the phone's ringing and it'll automatically take the call - a feature that worked perfectly in our tests. However, if you're not too enamoured of this feature, you can switch it off.
There is a slight learning curve to this headset, thanks to its standard multi-tasking buttons, but you're eased-in gently with voice prompts. If you max-out the volume control, a nice American lady tells you so. She also gives you a heads up when you switch the headset on or off, and lets you know how much talk time you have left on start-up.
The Plantronics Voyager PRO isn't quite as stylish as the Jabra Stone or the Aliph Jawbone Prime, but it offers better sound quality than the Jabra and more features than the Jawbone. As such, it wins our recommended seal of approval.
The Plantronics Voyager PRO is a quality headset that's worth paying its premium price for. Its noise cancellation is effective, and overall sound quality is beyond reproach. The only drawback is that it's not as stylish as some rivals.
