Conclusion: With its integrated proximity sensor, the comfortable, great-sounding Plantronics Voyager Pro HD lets you switch calls between handset and headset simply by placing it on your ear. Only if it weren't so big.
Pros: Stellar sound quality. SmartSensor proximity-sensor technology works well. Supremely comfortable. Very good sound quality.
Cons: Still larger than what most people want to wear, at least in public. Vocalyst service costs extra after the first year.
Conclusion: The Plantronics Voyager PRO combines excellent audio quality with comfort, making it an ideal headset for those wanting to stay connected to take those important calls. It isn't a design that will appeal to, or be practical, for all users, but we found it to be consistently good in performance in a number of situations.
