A small battery-powered headphone amplifier in a black ABS case, sized to sit under a phone or player. It is rated for headphones from 16 to 300 ohms, with 40 mW into 16 ohms, a 100 dB signal-to-noise figure and 0.0003% distortion. The 1000 mAh battery is quoted at more than 8 hours of use. It suits listeners with high-impedance or insensitive headphones who want more volume and headroom from a phone or laptop, but it is a bare unbranded amp with no tone controls, no gain switch and no balanced output, so it competes on price and portability rather than features against branded portable amps.
