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

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.

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.

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.

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

Sound quality; noise cancellation; and transmission clarity is great

Earbuds fit poorly and are too flimsy to keep from falling out; No caller id announcement

Appears to be a good quality product. It was easy to setup, and powering the device on and off is very straight forward. So far it seems to hold a charge all day playing music from the phone, as well as making a receiving calls.

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