This is the first time I have implemented a room video conferencing solution that didn't feel like torture. Right away from the unboxing of the equipment and the clear instructions I was satisfied. The full Teams Room kit had multiple options for cabling and detailed configuration options. It immediately connected to our Office 365 environment and we were live very quickly. We had one hiccup with the pass through on the Tap system but there was a firmware update available already that resolved it immediately.
Perfect for use in a noisy environment (i.e. an internet cafe/outside whilst walking) as the Active noise cancellation blocks out the noise from around you, allowing you to HEAR and crucially for far end to hear you. The base sound in the headset is particularly good for music with better capability than some more expensive dedicated music headsets (like BOSE). Battery life is exceptional and if you do end up running out, you can plug in the USB cable to your laptop and charge whilst using the headset which is super useful. Where you have BACK TO BACK meetings, long periods of use will mean you do get hot so this must be taken into consideration
As these are over the ear/enclosed, they are very effective, but long periods of use can end up meaning you can get sweaty/uncomfortable. Difficult to improve on this situation other than to switch between using these and an external Epos desk speaker.
The Rally units are a significant improvement on the Dolby units, providing a more capable interface with better screen sharing capabilities. The units are significantly cheaper than the Cisco units, however they do not offer the remote management capabilities of the Cisco units.
Jabra is one of our other main headset suppliers, and their Evolve and Speak range are regularly used within our organisation. Sennheiser ADAPT series comes down to personal choice from users, much like how there are iOS and Android users, but the Sennheiser ADAPT range (particularly in the case of the MB660) is one of the premium headsets that users have expressed an interest in for its overall capabilities.
For production/broadcast users, this compares favourably with dedicated music headsets but is more reasonably priced.
For staff on regular VC/AUDIO calls, this has been seen as a very capable premium headset that pays for itself in terms of build quality/audio quality and battery life.
