Plantronics P51N Polaris Supra headset is the most popular headset in the world, the Supra owes its popularity to the perfect balance between light weight, superior sound and outstanding comfort. The dual earpieces have a yoked double cable, which gives greater clarity by providing sound in both ears. Polaris models are for use with phone systems with built-in amplifiers. Important Note: Plantronics Polaris Headsets can only be use with telephones with a headset jack built-in (ie. Nortel, nec, etc). If your phone does not have a headset jack and internal amplifier, then the Plantronics H-series Headsets with an external amplifier such as the Plantronics Vista M22 are a good solution.
