The most common use for a headphone amp is to feed multiple sets of headphones from a single headphone socket. They can also provide some amplification if your original headphone out signal is too weak.
See this Sound on Sound article from Martin Walker for a helpful explanation of when you might need a headphone amplifier. Also, check the Wikipedia article on headphone amps to understand the two different ways the term is used.
