There is a whole world of headphone solutions from cheap to outrageous. One of the first things you should decide is how much you want to spend on your listening system.
Generally speaking, the headphones are more important than the amp. So select the right headphone first. If you are going to spend less than $75-$100, you probably don't need to be looking for a pricey headphone amp.
Once you get into the more expensive and accurate headphones, you'll want to buy a dedicated head-amp to get the most sound quality performance from them. Amplifiers don't so much make the sound louder as they make the overall sonics clearer, better extended, and more dynamic. Keep in mind if you get excellent headphones and don't buy a quality headphone amp to partner with them, you very likely won't get your money's worth out of the cans and will only be hearing a small part of their full audio capabilities.
