The HeadRoom Total AirHead is a portable headphone amp a little money can buy. The Total AirHead isolates your player from the complex load of the headphones while driving them with the authority and finesse of quality power amplification. The Total Airhead is very compact (3"x1"x4"), and it weighs a total of five ounces. It can be powered by four AAA battery cells or by low voltage DC power using a converter. Each amp/processor is fitted with two headphone jacks to accommodate two listeners at the same time.
