Plantronics is a Bluetooth headset brand we're very familiar with here at SlashGear, having tested the company's past few generations of models. Of course, that developing heritage can be both a blessing and a curse: the bar is set high, and any new headset needs to not only offer performance to match the price-tag but justify its existence over its predecessors.
