Are wireless headsets reliable in busy open-plan​​ offices?

Yes, with DECT technology you can have hundreds of headsets all working in close proximity and expect no interference.Similarly for Bluetooth models as well. Just remember to place the dongle or base in a clear spot, and keep firmware updated to avoid odd pairing issues after system changes. In larger open-plan floors, DECT wireless headsets cope better with crowded radio environments, while Bluetooth works well within a shorter radius. When teams coordinate across larger sites, a wireless intercom headset could be the perfect solution to working collaboratively with colleagues in person and those on remote calls.
