It's funny that the "phone" part of "smartphone" has somewhat gotten lost. Many of us prefer typing to communicate rather than frightful human interaction. Then there are those who rely on vocal communication to function on a day-to-day basis.

Earlier this year Sennheiser released Presence, a Bluetooth headset geared towards business professional's on-the-go, and Technology X got the opportunity of taking one for a test drive.

Sound transmission is good , not great. Same is true of comfort both in and around the ear.

Works great! Exceptional battery life means I don't have to recharge for DAYS. And it has outstanding range; I can be over 60 feet away from the phone and the connection remains strong.

This is the best earpiece I've bought. Bose is my fave but this one is just as clear. Noise cancelling is superb.

I have been using the Sennheiser Presence Business 506066 Wireless Bluetooth Headset for 2 days now and have had great performance of of it. Great sound quality for both myself and the party on the other end. Battery life has been as stated. This product meets our exceeds all my expectations.

Very nice headset. My wife loves it. Voices are very clear and the controls are easy to operate.

Build quality is very good, connected to both Lync and Mobile phone with very little effort. Highly recommended for those who spend hours on conferences calls via a mobile or Lync.

This headset is great! It's been perfect in every way.

"Very hard to hear. Looks good and is comfortable but did struggle to use as you can't hear the other person.
