Is because the new sound piece is made about 30 percent smaller than the 4S
But it's very loud for it's size and the sound quality is higher than the iPhone 4S but just a little quieter but it's not a big deal...trust me if you compare it to the iPhone 4S..you will see the iPhone 5 sounds way better and the bass is worth it.
-Most people did say the 4S sounds louder
and even on YouTube video review.
Unless it depends on what batch it is...
