My two favorite features of the Total BitHead are its USB connectivity and its crossfeed circuit. You also get a short gold-plated 3.5-mm to 3.5-mm cable and a short USB cable for connecting to your computer. The package includes three rubber feet and three pairs of Velcro dots so you can mount the BitHead on your laptop or attach your iPod to the BitHead. The internal components are very impressive, and best of all, the high-end DAC that used to cost $70 extra now comes standard. The back has an analog 3.5-mm line-in jack and a standard USB 2.0 mini port. On the front, there are two 3.5-mm headphone jacks and two switches - one for power, the other for the crossfeed circuit - plus a volume wheel. The top of the unit is a rubber flap that peels back to reveal a battery compartment for four AAA batteries, as well as a gain switch in case you need to power speakers or very high-impedance headphones. 75″ thick, and it weighs only 7.5 ounces - that’s just a couple ounces more than an 80GB iPod. The Total BitHead measures 3″ wide by 4.5″ long by. And it’s got some pretty awesome tricks up its sleeve too.

If you’ve got butt-kickin’ headphones from companies like AKG, Grado, Etymotic, Sennheiser, Shure, or Ultimate Ears (to name a few), you should seriously listen up: HeadRoom’s Total BitHead (just reduced to $149!) beefs up the sound from any audio source in a way that used to require clunky gear and an AC power source - but in a pocket-size little box that can run on batteries or your computer’s USB port.
