With numerous agents talking on the phone at the same time, call centers typically offer users dual-ear headsets which serve two purposes. First, by having both ears covered, the user can hear more clearly and focus better on their calls. This improves call efficiency, because you don�t need to ask for information to be repeated and agents won�t take down incorrect information when taking orders. Second, when you cover both ears with a Plantronics binaural headset, you will significantly lower the overall volume of the call center, because users no longer have to talk over each other. The Plantronics EncorePro HW520 headset is one of the most popular headsets when it comes to call centers and offices where employees need to focus on callers and not be distracted by background noise. Built with laser-welded construction, the HW520 is made to last and be comfortable for 8+ hour shifts.
