This portable headphone amplifier was created with the aspiration to convey high sound quality solely through the design itself. Its round shape rests nicely in the hand and, at the same time, it offers surface area for an intuitive four-way control unit. The device is small, for instead of containing a rechargeable battery it is powered by the connected audio device. Except for the clip, the amplifier is entirely made of aluminium. It is available in black, white and silver and thus blends well with most device and cable colours.
