The red and blue FiiO FA7 Quad Driver Balanced Armature In-Ear Monitors feature four drivers per ear with a 4-way crossover and custom-IEM-like comfort, well suited for musicians, engineers, and audiophiles. The FA7 is DLP 3D printed using hypoallergenic resin imported from Germany that is precisely crafted for consistent sound and reduced sonic resonances, allowing the music to flow through unimpeded. The skin-friendly resin is medically certified and is both comfortable and antimicrobial, while being extremely durable and resistant to discoloration.
There are four Knowles balanced armature drivers. The bass is handled by the CI-22955, which features a large diaphragm, resulting in a quick response with low distortion. Mids are provided by the classic and proven ED-29689, which provides a full, sweet, and unfatiguing sound, while the treble is produced by the dual-BA SWFK-31736 driver, which provides extended and detailed highs for a natural and clear sound. The integrated, tuned four-way crossover ensures a wide, deep sound stage with dynamic bass, crystal clear vocals, and highly detailed and smooth treble.
The standard 3.9' FA7 cable is made from high-purity monocrystalline silver-plated copper wire, ensuring the audio signal is transferred with minimal distortion and without loss for a transparent sound. The cable utilizes MMCX earphone connectors, allowing the cable to be replaced should something go wrong, while the 3.5mm L-shaped stereo jack is gold-plated to ensure solid signal transmission. The FiiO FA7 includes 13 pairs of ear tips: three different sets of small, medium, and large, which are designed for either bass-emphasized or vocal-emphasized sound signature. Also included are three pairs of foam ear tips in medium and one pair of bi-flanged ear tips. Hard case, cable wrap, carry pouch, and cleaning tool accessories are included.
