A friend made this for me to introduce me to the benefits of a headphone amp. It is ok for powering easier to drive headphones but now that most of my headphones are 250ohm or greater I don't use it anymore. It is kind of unique as it is NOT portable; uses a OP A2227 chip, assembled in a cool mini dj equipment case and has an adaptor. The Fiio E3 mini amp is well documented here. It has been used for about a month. Asking $55 usd shipped for them both to Canada/US.
