Apple makes the following claim on its web page for enhanced audio on the iPhone 5: Enhanced audio on iPhone 5. Apple EarPods are just the beginning of the improved audio experience on iPhone 5. Its designed with three microphones: one on the front, one on the back, and one on the bottom. The front and back mics work together to achieve beamforming a technique that helps iPhone focus on sound from the desired location for clearer audio. New noise-canceling technology reduces background noise. So when you hold iPhone up to your ear in a loud room, you hear what matters most: the voice on the other end. Can anyone verify the italicized improvements? Does the voice on the other end of the phone call sound better and clearer, and more "hearable" in a noisy environment? Anything special you have noticed that relates to quality of sound?
