Pro-Ject Head Box S2 headphone amplifierThe Pro Ject Head Box S2 is a very compact headphone amplifier that still packs a punch. With both 3. 5mm and 6. 35mm sockets and a high 725mW output power it can even drive two headphones at once if required. It has RCA inputs and RCA loop outputs (so that you can link other items after without the headphone amplifiers volume control having any influence) and a 'wall wart' external power supply. Specifications Headphone Output 3. 5mm Mini Jack + 6.
