Plantronics Discovery 645 Bluetooth Headset

Discovery 645 wireless headset improves upon the ultra-light and comfortable Discovery 640 by adding a Digital Signal Processing (DSP), which reduces background noise for improved sound quality.

The headset retains its innovative charging system, which is perfect for road warriors or commuters. To charge the Discovery 645, insert the headset into the unique, pen-size carrying case and attach the bundled compact wall charger to the bottom.

Unlike other headsets, you are not restricted use just the Plantronics charger - you can also attach a Nokia, Motorola, Sony Ericsson, or Siemens wall or car charger. In addition, you can attach a module that contains a single AAA battery (see picture to the right). This let's you easily charge the battery when away - a single battery will charge the headset full two times

The Discovery 645 offers up to 15 hours of talk time (and 70 hrs of standby time) when used with the AAA battery to charge the headset between calls. Without AAA battery, the headset offers up to 5 hours of talk time between charges.
