FiiO F9 Hybrid 3-way balanced In-ear Monitors

The FiiO F9 Earphones are balanced Hi-Res in-ear monitors. The F9 utilises a dynamic driver made of PEK (polyether ketone) polymer nano-composite, known for not only being tough but also being light. 

This allows the F9's dynamic driver to be highly capable of producing quick, detailed, and extended bass. They utilise a hybrid design in which each channel is composed of one dynamic and two balanced armature (BA) drivers. The 9.2mm dynamic driver is specifically tuned to produce bottomless lows while the two BA drivers precisely portray extended upper-mids and highs.

The F9's outer aluminum shell is meticulously crafted using CNC systems – impressive already, but it doesn’t stop there. The shells are then carefully hand-polished and matched, before going through sandblasting and anodisation. This complex overall process ensures that the F9 has a masculine, robust shell that is yet encapsulated in a tender beauty.
