These headphones are designed to fit the ear canals by taking into account the distance and angle to the tragus, as well as the upper and inner parts of the ear canal. This concept has led to an extremely simple configuration, comprising two circles, that fits perfectly into the ear canals. The headphone units have recessed areas so that they can be held and put into the ear canals easily. The large 13 mm drivers ensure audio quality and texture, producing sharp and clear high-range audio as well as deep mid- to low-range audio. These brand-new high audio quality headphones embody the fashion and style of adults.
