I worked for an office who had the wireless plantronics headsets. The most difficult thing was we had 3 different head sets and keeping track of which head set went to which base was the most confusing. We always had to make sure they were on the chargers for the night. Sometimes we even accidentally took them home with us. For the wireless mice and keyboards, they take batteries. We could technically use re-chargables for those so it would not as expensive.
I am not trying to rain on your parade. I am just speaking from experience.
