Answer 1

You don't have to have headphones or a speaker hooked up to listen to music.

Answer 2

You can listen to music with iPhone without using your headphones because like most phones today, iPhone has speaker phone functionality, thus it has speakers!!!.

Though the output won't be great, it still has a reasonable good quality.
