“That tiny thing is a combined DAC and headphone amp? You’re Fulla Schiit!” you might be saying. And you know what, you’re right. That’s Fulla.


  • And it’s not only a combined DAC and headphone amp, it’s also the least expensive quality dongle-DAC/amp on the market, with a knob for volume control—connected to a real live analog volume pot, not a volume control chip.

  • Total Convenience

    Just plug Fulla into virtually any computer’s USB port and you’ll be enjoying great tunes instantly. No drivers, no fiddly software, no confusing volume buttons—on either Mac or PC. It also works (with some caveats) on Linux, iPhones, iPads, and Android devices. Plug it in, attach your headphones, and turn it up. Done!

    A Dang Good DAC

    Like Modi, Fulla uses a CM6631 USB 2.0 receiver and the AK4396 digital to analog converter—not antique 1.1 or an integrated DAC with headphone drivers built in. The AK4396 is one of the best-measuring, most capable digital to analog converters on the planet, used in systems that cost many times the Fulla’s price.

    Plenty of Power for Most Headphones

    After the DAC, a gain stage using precision thin-film resistors and film capacitors filters and boosts the output, up to 300mW into 32 ohms. This means plenty of power for most headphones, together with a vanishingly low noise floor and low output impedance that make Fulla great for IEM use.

    Made in USA. No, Really.

    By “made in USA,” we mean made in USA. The vast majority of the total production cost of Fulla—chassis, boards, assembly, etc—goes to US companies manufacturing in the US.
