Excerpt: I have tried 3-4 bluetooth units and this is by far the best. The mechanism to hold it in/on your ear is adjustable with different sized pieces. The on-off slide mechanism is very clear and not confusing when a call comes in. The sound quality is exceptional incl noise-cancelling.
Excerpt: Very satisfied with the quality of sound and the noise reduction. I had Boise series 2 before I bought the SennheiserPresence UC but it stop working after a few years of use. I bought one for myself and one for my wife.
Excerpt: The sound quality is great. The noise cancellation is great. Battery life is great. Deliver was fast. The only issue I have with the unit is the slider to turn the unit on tends to wear out over time and the unit can easily turn off should it touch anything.
Excerpt: In 2 days I returned it: got pain in ear, buttons toooo small, outside noise. Only good side - 10 hours talk time, but if you try Bose 2 (4.5 hours talk time) - for you it will be totally unacceptable anything except Bose 2.
Excerpt: I have owned only a few headsets in my lifetime. I have tried both Motorola and Jawbone. And I am here to say that Sennheiser is the best when it comes to business grade Headsets, not to mention the quality of their UC integrated Blue tooth dongle.
