Listening head set with hard or soft ear-pieces

摘要

The ear-pieces (1) are geometrically moulded from material concentrating the sound waves in the form of a paraboloidal reflector. The ear-pieces are flexible attached to the head-strap. The resonance frequency of two hard ear-pieces are lined with soft material. The head-strap can be adjusted to head size. The rims of the ear-pieces are padded.
