In normal use, ten meters is a good guide to what can be achieved between two Bluetooth devices indoors. When developing a Bluetooth device, you can give your device a better range by selecting the Bluetooth chip with the best receiver sensitivity and output power, and making sure that you use a good antenna.
Class 1 devices transmit at 100 mW with a range of 100 meters or 328 feet. Class 2 devices transmit at 2.5 mW with a range of 10 meters or 33 feet. Most Bluetooth headsets and headphones are common Class 2 devices. Lastly, Class 3 devices transmit at 1 mW with a range of fewer than 10 meters.
Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range based on low-cost transceiver microchips in each device. Because the devices use a radio (broadcast) communications system, they do not have to be in visual line of sight of each other; however, a quasi optical wireless path must be viable.
Range. Bluetooth 1.0 can link up to eight devices within a radius of about 33 feet with a capacity, or bandwidth, of 700Kbps. A later revision of the Bluetooth specification, Bluetooth 2.0, can transmit at up 2.1Mbps within a radius of about 100 feet.
A: Bluetooth is designed for very low power use, and the transmission range will only be 10m, about 30ft. High-powered Bluetooth devices will enable ranges up to 100m (300ft). Considering the design philosophy behind Bluetooth, even the 10m range is adequate for the purposes Bluetooth is intended for.

Range is essentially going to be good enough for a normal sized room to be covered. It can be longer or shorter depending on environmental circumstances, but remember that bluetooth was created to implement short range connections. A bluetooth device can be part of a piconet of eight devices, one master and up to seven slaves.
Bluetooth 4.0, the newest version of the technology, is about to change all that. The bad Bluetooth rep I personally use Bluetooth daily, and love it. My trusty LG BHS-700s works like a charm. For ...
Bluetooth Range. Among different bluetooth specifications, there are 2 most popular classes (types) of devices: Class 1: range up to 100 meters (in most cases 20-30 meters) Class 2: range up to 30 meters (in most cases 5-10 meters) Additional facts: the range depends not only on the transmitter, but also on the mobile phone which is receiving ...
Bluetooth® technology proves the power of connection. Nearly 4 billion devices will ship this year using Bluetooth to connect. To phones, to tablets, to PCs, or to each other. And Bluetooth enables multiple ways to connect.
