In 1969, when Neil Armstrong bounded off Apollo 11 onto the moon and said, “That’s one small step for man; one giant leap for mankind,” he was using a Plantronics headset. Remarkably, Plantronics had been formed less than a decade earlier by two airline pilots dissatisfied with their flight headsets. The lightweight models they devised, and their subsequent innovations, soon were in wide use by pilots, call centers, gamers, and even executives who didn’t want to hold a phone while practicing on the in-office putting green. Today, headsets remain the main focus of Plantronics’ work, especially Bluetooth ones; the company lays claim to helping bring Bluetooth to popularity with its Discovery 640 headsets line.
The instructions were poor and there were no instructions for the charger case to decipher the indicator lights. I went on You Tube for complete instructions. Other than that, it works fine. I'm pleased with it even with it being an older model.
Plantronics earpieces are fabulous. I love this pieces it's comfortable in my ear, the clarity is perfect, the charge time and talk time last the entire day. The earpiece does everything for you so you don't have to touch your phone. The only down fall is the old one would allow me to be 75 feet away before distort, but this one is only 25ft so I have to keep my phone a close to me. I love it.
Nice headset. Definitely cheaper than anywhere else brand new that I've found (think Amazon and Best Buy). Had this one before but I accidentally lost it so had to buy another. Wish volume could go up just a little to compensate for noise when I'm driving my truck.
