This week the Bluetooth SIG unveiled the specifications for Bluetooth version 2.1. With improved pairing and lower power consumption, it will continue to make our lives with our BlackBerry devices easier. This protocol has seen an incredible success in the industry and Bluetooth technology is shipping today at a rate of over 13 million devices per week. Bluetooth 2.1 is only at the specs level but we already can benefit from v2.0 available today on the market.

Bluetooth 2.0 was specified in November 2004 and is backward-compatible with 1.x. The main enhancement was the introduction of an enhanced data rate of 3.0 Mbps. When using a Bluetooth headset paired with your BlackBerry, v2.0 will bring you the following advantages:

- Three times faster transmission speed
- Lower power consumption
- Simplification of multi-link scenarios due to more available bandwidth

Basically the main idea is that because the headset is able to burst two to three times more data in a transmission, it is able to sleep longer between transmissions. This has a dramatic effect on the battery life.

So if you are concerned with battery life, here is a list of Bluetooth 2.0 Headsets you might want to use with your BlackBerry:

- Cardo Scala-700
- Sony Ericsson HDH-GV435
- BlackBerry HS-655 Bluetooth Headset
- Plantronics 665 Bluetooth Headset
