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

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.
