Plantronics H51NS Supra Headband Headset Shielded with Noise Cancelling Mic

The H51NS Supra Monaural Noise-canceling models have all the features of the standard Supra headsets, but use a unidirectional, noise-canceling microphone mounted on a highly flexible stem in place of the trademark clear and curved Plantronics voice tube. By eliminating up to 75% of all background noise, the noise-cancelling headsets make speech much clearer in noisy environments.
