Fiio FH5s quad driver earphones are packed with innovative design elements.
Dual dynamic drivers + Dual B. Armature drivers
3 Tuning switches, to fine tune Bass / Mid / Treble
Open back design for more spacious sound
Venting relieves pressure for better comfort
Swappable plugs on the balanced cable
The Fiio FH5s are designed around a 12mm Beryllium plated bass driver + 6mm Beryllium plated Bass/Mid driver + dual Knowles BA drivers for the highs. Sound quality has been improved from the FH5.
FH5s has 3 dipswitches on each earphone so you can fine tune the sound to your taste. You can adjust the bass / mid or treble to just the response you prefer. Its also great if you change gear or if your preferences change over time, the earphone can be easily tweaked.
The rear panel is perforated - this provides less isolation but a larger sounding, more spacious soundstage - always tough for earphones to pull off. The open design also reduces pressure within your ear canal, for better comfort. The housing shape is very ergonomic
The silver plated copper cable is detachable via mmcx connectors and the plug is also swappable - a 3.5mm and two balanced plugs, 2.5mm & 4.4mm are included. Its easy to swap plugs for compatibility with new dacs and portable devices.
