The Bluetooth headset comes with a range of innovative features today. This includes the full voice command control.
Do note that all the latest Bluetooth versions are backward compatible. This means that even if you are using the Bluetooth headset having the most basic Bluetooth features, you will not have much to bother about. Even the Bluetooth version 1.1 offers the basic features including voice dialling, call mute, besides the last-number redial.
The next was the Bluetooth version 1.2 that introduced new features which were able to eliminate radio frequency interference. This was achieved through frequency hopping. All this helped to add greater security in order to protect against snooping as well as tracking.
Next was the Bluetooth 2.0 that was responsible for bringing in higher connection speeds besides improved performance, along with lesser power consumption. The version 2.1 was able to improve pairing without the need for any PIN, and it required still lower power consumption besides offering more security. With the Bluetooth 3.0 came the ability of using a Wi-Fi connection in order to increase the speed of data transmission. The latest is the Bluetooth 4.0 that has the major feature of strong power management skills.
Besides the different versions of Bluetooth specifications, there are various Bluetooth profiles too. A Bluetooth profile refers to an interface or behaviour. It is the way in which different Bluetooth devices tend to communicate with each other. Both the devices, such as the Bluetooth headset and the phone must support the same profile in order to communicate with one other. The most common Bluetooth profile that is available today in cell phones is the Headset profile. This supports the use of standard mono Bluetooth headset for making calls.
Another is the Advanced Audio Distribution Profile or A2DP that is also known as the stereo Bluetooth headset profile. This allows a dual-channel audio stream. This is why the Bluetooth headset in case will be a stereo headset. A2DP is highly popular especially with MP3 as well as music phones as it allows the users to listen to music wirelessly. It can be used for making calls too. With this Bluetooth headset, users can switch between music and a call at the touch of a button.
The Audio/Video Remote Control Profile or the AVRCP is able to provide a standard interface in order to control TV, hi-fi equipment, and other such devices. This profile allows a single remote control or some other device to control the AV equipment that are accessible to the user.
