Listening to music from a portable music player on headphones is very common today. Many audio enthusiasts may be somewhat dissatisfied with the sound quality from portable music players, which may make the wrong design compromises in an effort to hold down costs, decrease size, improve battery life, or other criteria. Or they may want an external audio system that is capable of driving the headphones to higher volume levels.
The purpose of this project was to build a higher power yet efficient headphone amplifier that connects to a portable music player and produces high-quality audio reproduction at higher volume levels. (Taken from EE410 Final Project Specifications)
