Check this out... It seems that the speakers are not as high quality that you would expect from apple. Go to your itunes store and search "Prevent this tragedy" by Alkaline Trio... When he sings a certain note in the song you will notice that the speakers cant handle it and the song turns down. This is when he sings "drown". Please let me know if yours does the same because all the ones in the apple store did it too and the genius had no explanation and they would not exchange it for me.
