The CS50-USB Wireless VoIP Headset from Plantronics allows you to conduct PC softphone calls away from your desk with remarkable range and clarity. The compact and lightweight headset uses 900MHz technology to provide clear communication and a wireless range of up to 300'.
The headset can be worn in an over-the-ear or over-the-head style. You can also use an optional neckband (sold separately) for behind-the-head wearing. The unit has a noise canceling microphone on an extended boom for optimal vocal pickup. There are call answer/end and volume up/down controls integrated into the headset, so you retain full functionality away from your desk. The unit also offers remote ring detection, so you know when you have an incoming call.
The headset's base connects to your PC via USB and works with a variety of PC softphone programs. The internal battery provides up to 8 hours of talk time per charge, so you can work all day without needing to recharge.
