Now that the iPhone OS 3.0 firmware adds stereo Bluetooth functionality to the Apple iPhone, we thought it would be nice to come back to stereo Bluetooth, and that it promises.

Motorola Rokr S9 HD with IPod Adapter

(List of participants: Motorola) Stereo Bluetooth and A2DP (Advanced Audio Distribution Profile), is essentially a Bluetooth profile that allows you to stream music from one device to another without using wires. This technology has been around for many years, and almost all the music phones have this feature. In fact, it was quite a disappointment that the original iPhone and iPhone 3G has not been built in that when they are first, given the iPhone in IPod heritage. Nevertheless, better late than never. In iPhone OS 3.0 update also brought stereo Bluetooth for IPod Touch 2 gen. If you have a music player, not the phone, you can also purchase additional stereo Bluetooth adapters, such as the Motorola D650 IPod adapter.

Bluetooth stereo headphones come in a variety of shapes and sizes. Some, such as, for example, Motorola Rokr S9 HD, designed for active lifestyles, as he shaped to hug the sides of the head. Others, such as, Samsung SBH-600, designed for serious audiophiles, especially with its promise of bass and stimulate. We also, as in the mono-stereo headphones, for example, Plantronics Voyager 855, which can change from mono to stereo headset option simply by connecting additional ear bud. One of the most popular stereo headsets among our readers, this Jabra BT3030, which is not really even a headset because it is a pendant that can be used with any pair of 3.5 mm-compatible headphones.

Most of these headsets have microphones, with the possibility of how to control the music player and phone calls. The sound quality is different from the headset to the headset, so be careful what you buy. For example, Samsung SBH-600 is perfect for listening to music, but not so much for calling - in the outgoing call quality is not so big.

A note on the music player controls: To ensure that you manage the player with the headset, the phone needs an additional profile called Bluetooth AVRCP (Audio / Video Remote Control Profile). This allows you to use the headset as a remote control so you can play and pause songs, fast forward through tracks, adjust volume, and so on. This is one of the few shortcomings in the iPhone OS 3.0 firmware - it has a very limited form of AVRCP. We can play / pause and the music volume with the headset, but we are not only able to change tracks right from the iPhone.
