Piano Forte Series

Dynamic driver earphones that value acoustic resonance.
An open / canal type hybrid with a unique open form that doesn’t use an earpiece;
employs horn speaker principles. The forte of this series lies in its reproduction
of the factors necessary for live music reproduction – a sense of openness and
spatial representation; it is a series that, once drawn to, you will not want to give up.
Piano Forte X- has a chromium copper housing that subtly expresses lingering notes
as they fade away. Piano Forte IX – has a stainless steel housing with clear sound quality.
Piano Forte VIII – has a brass housing and the bright resonance of brass musical instruments.
And Piano Forte II – the entry model instilled with the design philosophy of
high-end equipment. Each of these models has its own unique appeal.

The Piano Forte X-VIII T series employs a silver-coated cable from Junkosha.
Changes have also been made to the internal specifications; the vast sound stage
of the original model remains as is, and a high level of sound articulation is achieved.

The series name – Piano Forte – is imbued with the desire to value acoustic resonance.
