The Longest Range Bluetooth Headset.

Able to send and receive a signal from your compatible cell phone up to a range of 328' - just over the length of a football field - this is the longest range Bluetooth® headset available, allowing you to leave your cell phone in your car while shopping or in your home while outside. It uses the Bluetooth® 2.0 specification and enhanced audio channel technology, which provides three times the transmission speed of older Bluetooth® headsets (up to 2.1 Mb per second), and removes echoes, pops, and clicks, resulting in consistently crystal-clear reception while consuming less power. Its built-in lithium-ion battery provides talk times up to eight hours with a three-hour charge from its included AC charger. It can be paired with two compatible devices at the same time (for Skype® calls from your computer) at the touch of a button. Requires Class 1 cell phone for full 328' range. 2 1/4" H x 2" L x 1 1/4" D. (3/4 oz.)
