I aimed at a design which is expected to be high-quality sound only by everybody’s looking at appearance.
Body form which adapts itself to a hand, and simple remote control operation.
It is the simple portable headphone amplifier developed for the purpose of enjoying a High-Resolution sound source easily.
Since body size was miniaturized, a battery was not built in, but the bus power system which receives an electric power supply from connection apparatus was adopted.
All appearance parts other than a clip are beginning to be deleted from the lump of aluminum.
