If you're a business professional that requires a clear, secure, and flexible communication solution, then you should consider the Sennheiser SDW 5036 Mono Wireless DECT Headset System. This headset allows you to walk and talk from up to 590' away with clear line-of-sight to the included base station. Your conversations are made to sound clear, even in a busy office environment, thanks to two noise-canceling microphones built into the adjustable boom mic and own-voice detection technology.
