Excerpt: This is our fifth Plantronics Voyager Pro HD Bluetooth Headset for use in in office, now we can't live without them. What is highly improved from earlier versions is the charge time. Full charge (which lasts for 20+ hours of use) takes less than two hours.
Pros: Clear Signal, Connects Easily, Fits well in ear, Good Sound, Good Volume Control, Lightweight, Long Battery Life, Noise Cancellation, Sounds Like Land-line
Excerpt: No complaints on calls but the static from the phone if it's more than 2 feet away is significant. Seems to have a bad delay on some calls. Doesn't fit well in ear even with 4 different earbuds but not uncomfortable to wear. Lots of software stuff to augment, even an app on the Android phone to confirm connection. Does pick up the phone call on placement into the ear but the device is a bit larger than others and doesn't slip on all that fast.
Pros: Connects Easily, Good Sound, Good Volume Control, Long Battery Life, Noise Cancellation
Excerpt: Sound quality is usually good, but it is still tough to clearly make out certain voice types in a car in the rain (too much background noise and can't get the volume high enough to compensate). Again, depending on the caller's voice type, or maybe their phone quality, occasionally the speaker crackles some when the caller talks. This gets annoying because turning the volume down low enough for this to not happen means I can't hear them. Comfort is fine.
Pros: Connects Easily, Long Battery Life, Noise Cancellation
