If you use an iPhone or iPod touch, you should plug into your iTunes and get Apple's latest iPhone OS 3.0 software update. This free update offers some great new features and updates to existing features.
We tested the Bluetooth A2DP with the Samsung SBH-500 Bluetooth stereo headset, the sound quality was really good. Note: Turn down the volume on both the iPhone and the headset first, because there is not automatic volume adjustment here. Might blast your ears out.
