Wireless headsets for corded telephones provide hand freedom for multi tasking around the office. Voice dedicated technology and digital encryption provide clear audio quality and digital security while limiting background noise. Choose a headset with voice tubes or one with extended boom and noise canceling microphones. Extended talk/stand by time allows you to talk for extended periods (up to 10 hours for some units) before requiring recharging. Wireless headsets for corded phones come in monaural or binaural design, with several different wearing styles including over-the-head, over-the-ear, or behind-the-head to provide you with ergonomic comfort. Recent studies show that workers who use wireless telephone headsets experienced a 25% reduction in discomfort and a 23-1/2% increase in productivity.  Pair a telephone headset with a handset lifter to create an office telephone system.
