Was at work yesterday listening to music on my iPhone 4s using my Bose SoundDock. I was listening to a song and noticed that the baseline was coming through scratchy and muffled. Then it it hit me to try listening to the same song on my 4 which I'm carrying around with me as an iPod. I don't ever remember the sound quality being that bad playing my 4 through the sounddock. So when I played the same song on the sounddock using my 4 the quality was perfect. Both settings were the same on both phones and it was the same song but the quality was completely different between the 4 and 4s. My question is does anyone know what could have caused this? Could it be the new iOS 5 which I don't have running on my 4. Could it be some sort of hardware issue with the 4s and the sounddock?
