LG Tone Pro headset

The LG Tone Pro is a pair of Bluetooth wireless stereo earphones. The IEEE 802.15 Wireless Personal Area Network (WPAN) standards can be traced to the IEEE Ad Hoc “Wearables” Standards Committee led by Richard Braley at FedEx in 1997. Bluetooth is described under 802.15.1, and ZigBee uses the 802.15.4 layers. While the basic Bluetooth technology was invented in 1994, it was not until the 2002 1.1 specification that it became stable and popular. A major step forward was the recent introduction of Bluetooth Low Energy wireless technology, which improves many of the power consumption and device speed-of-discovery problems that have limited Bluetooth’s usefulness for wearable devices.
