Bluetooth 2.0 vs 3.1 vs 4.0

Bluetooth 2.0 doesn't have features like voice recognition and it sucks in more power, making it difficult to use for longer periods. Version 3.0 and higher rave of Bluetooth range of upto 100 meters where as 2.0 goes upto only 10

Version 3.1 is fast but the 4.0 is faster and also uses less power in transmitting data even it the device is 50 meters away. Both support multi point connections. however connections wit 4.0 are more secure.

Always go for the last version: it is more reliable, faster and usually more power-friendly.
