FiiO FH7S

Overview

The FiiO FH7S is a flagship five-driver hybrid in-ear monitor featuring a 13.6 mm DLC dynamic driver and four custom Knowles balanced armature transducers.

Sharing acoustic engineering DNA with the flagship FH9, the FH7S utilizes a 2nd-generation 13.6 mm DLC (Diamond-Like Carbon) dynamic driver for sub-bass power, custom Knowles DFK balanced armatures for rich midrange vocals, and Knowles SWFK-31736 balanced armatures for airy treble extension. Its semi-open acoustic cavity design relieves ear canal pressure, complemented by interchangeable acoustic sound filters and swappable audio plugs.
