For users who demand superior performance and good value, the H500 offers the best of both because of longer talk times with a more stylish, compact and comfortable design -- all at a reasonable price. This headset is both discreet and stylish, yet highly functional. The overall compact size and lightweight of this headset allows for easy storage when not in use. Also, the lengthy talk and standby times include up to 8 hours of talk time or 150 hours of standby time from a single full charge (travel charger included). Simply press the multifunction button, place the headset on your ear and a link is automatically established (must pair the headset with your phone the first time it is used). The multifunction button allows you to place, receive or end calls, all with the push of a button. With Bluetooth wireless technology, devices work together up to 10 meters (30 feet) away. Consider pairing it with your Bluetooth enabled PC for hands-fee Voice Over IP use. An adjustable earhook allows the headset to be worn on either the left or right ear. You can also easily adjust the volume and mute your call from the headset. Motorola wireless accessories are compatible with any Bluetooth 1.2 enabled mobile phone or device. Seamlessly expand your wireless reach, universally.
