In contrast to most similarly expensive competitor models, the technics uses a dynamic single-unit driver. They are, however, supposed to nevertheless reproduce frequencies up to 100 kHz. In order to achieve this goal, Technics uses an aluminum diaphragm that is only five micrometers thin and has an impressive diameter of 10 mm. It is supported by "magnetic fluid" and an "air control chamber". The housing is made of magnesium due to its good damping properties, while Technics uses light and high-strength titanium for the sound outlet. Included are two interchangeable cables – one symmetrical and one asymmetrical – as well as 4 oval and 4 round earplugs each.
