  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.

•  Plantronics uses a superior voice tube technology and design, with patented SoundGuard®Plus and Call Clarity™ technology, which contribute to the Supra headset's excellent sound quality.

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.
