Stereo Headphones (Instruction Manual)

The sensation you have experienced at a concert hall-you may wish to enjoy that sensation once again at your home. In most

successfully. lt leaks no sound from the earpieces, nor does it permit external noise to interfere your listening. It lets you enjoy in
total privacy a rich, vivid and really dynamic concert hall music in a true high fidelity any time, anywhere-in your bedroom, in the
living room or in the quietness of midnight.
