About the Total BitHead

The HeadRoom Total BitHead is a compact, battery-operated headphone amplifier and USB digital-to-analog converter designed to enhance headphone audio quality from computers, portable music players, and other sources. It features a built-in Burr-Brown PCM2902 16-bit DAC capable of handling up to 48kHz sample rates, dual headphone outputs, and a switchable crossfeed circuit that improves spatial imaging by blending audio channels for a more natural soundstage. The amplifier includes a low/high gain switch to optimize output for headphones of varying impedance and efficiency. It runs on four AAA batteries for over 25 hours or can be powered via USB when used as a DAC. The Total BitHead improves bass response, smooths high frequencies, and provides a cleaner, more dynamic sound compared to typical headphone outputs on portable devices or computers. It is praised for driving high-impedance headphones effectively and for its ability to bypass low-quality internal sound cards when connected via USB. The device also includes volume control, power and clipping LEDs, and a durable, compact enclosure suitable for portable use.
