This is a small battery-powered headphone amplifier with a 3.5mm input and output, a two-stage gain switch and a volume knob. It is built to drive headphones from 16 to 300 ohms from phones, computers, MP3 players and CD players, adding gain and a cleaner stereo signal. The aluminum body and 1000mAh battery (rated over 8 hours) put it in the budget portable-amp class, where rivals often add a DAC, Bluetooth or a second output. It suits wired-headphone listeners whose source is too quiet or too thin, not people who need wireless or digital inputs.
