A small aluminum-bodied headphone amp with a built-in 1400 mAh battery, a single 3.5mm input and output, and a volume plus bass control. It is meant to add gain and a bass lift to phones, PCs and consoles that drive headphones weakly. Output falls as impedance rises: about 62 mW at 32 ohms but only 10 mW at 600 ohms, so it suits easy-to-drive headphones far better than high-impedance studio models. Against dedicated portable amps from established audio brands it is simpler and cheaper in build, with no DAC, no gain switch and no display.
