These Plantronics Discovery™ Bluetooth Headsets combine the latest wireless technology with a sleek design to give you convenient hands-free call communications wherever you go.

Using Bluetooth technology, you can roam up to 33 feet (10 m) from Bluetooth devices, such as laptops, PDAs, or phones, that support headsets and hands-free technology. Ultralight and ultracomfortable, Discovery headsets weigh just a third of an ounce, fit discreetly in your ear, and include three sizes of soft gel ear tips for a personalized fit.

For even more convenience, you can use your existing phone charger to recharge the headset. The length of talk time from a charge depends on the model you order. The Discovery 640 provides up to five hours of talk time between charges; the Discovery 645 DSP provides up to three hours of talk time.

Both models come with four charging adapters that work with most phone chargers (including those from Nokia, Motorola®, and Sony-Ericsson®), eliminating the need for a separate charging cable. An AC adapter is also included.

What's more, each headset system includes an innovative charging system that uses a AAA battery charger to extend talk time up to 15 hours for the Discovery 640 and up to 9 hours for the Discovery 645 DSP. This way, your phone is ready when you are.

Plan to use the headset in a busy office, call center, or other noisy environment? Then take a look at the Discovery 645 version. For optimal sound quality, it features built-in digital signal processing (DSP) technology that actively reduces transmitted background noise, so your voice can be heard clearly by your caller.

Both the 640 and 645 feature a one-touch call-control button and support last number redial, as well as voice-activated dialing so you can place calls hands free when you’re on the go*. The headsets also support multipoint technology, which means you can connect simultaneously with two different Bluetooth audio devices and have calls received on either device ring through to the headset.

With each headset, you also get an ear stabilizer for a more secure fit and a stylish, chrome pocket case that provides convenient and secure storage for the headset and vibrates to alert you to incoming calls.
