The Voyager Pro has been a great Bluetooth Headset for mobile phones. Now adding the ability to use it with VoIP and UC only makes it better. You can use one headset for two completely different applications, being mobile phone talking and VoIP/UC talking. With the dual mic, background noise really is reduced and the headset fits above and behind your ear for comfortable and secure wearing. Also, with different sized ear gels included, you will finally be able to find one that fits your ear.
