plantronics supra headset h51n monaural noise canceling The Supra headset owes its popularity to the fact that it combines light weight with superior sound quality and outstanding comfort. A fully adjustable headband design provides good stability, while a soft ear cushion not only gives optimum comfort but also helps buffer distracting background noise. The Supra Monaural Noise-cancelling headset model has all the features of the standard Supra headsets, but use a unidirectional, noise-cancelling 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. h61n Availability: Usually ships the same business day.
