FiiO Electronics Technology Co.\u00a0Ltd., launched the FiiO FA7S 6 Unit Moving Iron in-ear headphones based on six balanced diaphragm drivers.<\/p>\n

\"\"<\/p>\n

The developers used Knowles HODVTEC-31618 emitters for low frequencies, Knowles RAD-33518 for high frequencies and DIBEI db646006 for mid frequencies in the FA7S, “each creature in pairs.” According to the manufacturer, they use a three-way crossover with a 2 + 2 + 2 design.<\/p>\n

\"\"<\/p>\n

TTX FiiO FA7S indicate that the new product can reproduce the frequency range from 10 Hz to 40 kHz.\u00a0As a result, the FiiO FA7S 6 is adorned with the Hi-res Audio logo.<\/p>\n

\"\"<\/p>\n

The FiiO FA7S has an impedance of 18 ohms and a sensitivity of 111 dB.\u00a0These in-ear headphones can be used seamlessly with a wide range of sources.\u00a0They naturally reach their full potential with high quality headphone amplifiers.<\/p>\n

One FiiO FA7S monitor weighs only 8.4 g, of course, without a cable.\u00a0The FiiO FA7S uses a 316L stainless steel body, a material certified for medical use.\u00a0This case is 3D printed using a laser sintering process.\u00a0Stylish appearance is achieved with CNC-milled lines on the outside and PVD surface coating.\u00a0FiiO FA7S is available in black and gold, as well as silver and blue.<\/p>\n

The cable is detachable and uses the familiar MMCX connector.\u00a0Not for the first time, it is a high-purity silver-plated single-crystal copper wire with a complex structure of eight strands of 152 conductors each and has a practical length of 1.2 meters.\u00a0The manufacturer equipped it with interchangeable twist-lock plugs according to the Fabrilous patent, according to which 3.5 mm stereo mini-jack, 2.5 mm stereo mini-jack and 4.4 mm PENTACONN are available.\u00a0FiiO FA7S can be connected both asymmetrically and symmetrically, depending on the version of the source device.<\/p>\n
