After some searching we bought a set of these for use in a data center environment. They offer moderate noise cancellation in an over-ear model. The mics pick up some of the fan's ambient noise, but you can raise the mic and it will automatically turn off. This feature ensures silence when you're not collaborating with anyone in the data center. Battery life is good and overall I'm happy with the price and performance of these headsets.
