1-Year Local Warranty. The FH7S channels the essence of the FH9 with not only a more-light body, but also an acoustic structure of 1 dynamic driver and 4 balanced armatures that democratizes plenty of cutting-edge technologies. Low frequencies are produced by the 2nd-gen FiiO-developed 13.6mm DLC driver, mid frequencies by the exclusively customized DFK BA drivers collaborated developed by Knowles and FiiO, and high frequencies by the Knowles SWFK-31736 BA driver. Based on the inner cavity design, tuning and crossover systems were redesigned to acquire smooth frequency response and resolving treble. 1. The music stage simply right in front of you, every music note floating around your ears The FH7S employs FiiO's 2nd-gen semi-open design. This semi-open design incorporates FiiO's system of balanced pressure relief between the front and rear cavities. The result is that when the drivers push air when making sound, that air encounters less resistance - resulting in a smoother yet detailed sound, natural timbre, large soundstage, and pinpoint accurate imaging. 2. Comfort from 0.4mm, debuting the all-new FiiO silicone ear tips The all-new FiiO silicone ear tips, HS18, are debuting for the first time in the FH7S. It chased for the best for every tiny detail. Picking optimal silicone materials, it is not only skin-friendly and durable, but also features merely 0.4mm thickness at the surface that touches the ears, allowing for better comfort and seal. 3. Cable upgraded for a new sound experience The FH7S comes standard with cable consisting of 8 strands of 19 wires each – for a total of 152 wires of silver-plated monocrystalline copper all individually isolated from each other. Compared to the FH7, the twist-lock swappable audio plugs allow you to easily change between 3.5mm single-ended and 4.4mm balanced plugs as needed. More surprises are waiting for you.
