When developing the FX15, the FiiO R\u0026amp;D team spent much time researching how best to utilize electrostatic drivers. Due to the low sensitivity of such drivers, special care must be taken to ensure they are not overpowered by the other dynamic and BA drivers in use. Otherwise, listeners will not be fully able to experience the unique sound that electrostatic drivers bring to the table.\u003c\/p\u003e\n\u003cp\u003e“Dare to be at the top” is an important part of FiiO’s corporate culture. FiiO does not merely use new techniques or materials simply to attract attention with new gimmicks, but rather chooses to fully research new methods to come up with products that fully utilize the potential of such new approaches. In a sense, “being slow makes you end up being faster.” The development of the FX15 embraces this ethos as the FiiO R\u0026amp;D team carefully made sure that dynamic, balanced armatures, and electrostatic drivers worked together in harmony to fully bring out the best of the latter before choosing to release this new IEM.\u003c\/p\u003e\n\u003ch3\u003e“Static” embracement of endless possibilities\u003cbr\u003eSonion electrostatic drivers\u003c\/h3\u003e\n\u003cp\u003eElectrostatic drivers are known for their high-frequency detail reproduction, but such drivers are usually used in extremely expensive IEMs out of reach out of most audiophiles. The FiiO FX15 employs 4 electrostatic drivers per channel that not only provide exceptional ultra-high frequency extension[1], but are exceptionally quick and able to reproduce every last detail in your music, giving the listener a taste of true high-end audio.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"FiiO FX15 Electrostatic Driver\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/Capture.png3.png?v=1694447195\"\u003e\u003c\/p\u003e\n\u003ch3\u003eSmoothly gentle A classic in the making \u003cbr\u003eKnowles mid and treble BAs\u003c\/h3\u003e\n\u003cp\u003eThe FX15 adopts the proven Knowles ED-29689 balanced armature driver to handle the mids and lower treble frequency ranges, due to the driver’s smooth, lush, yet detailed sound. In addition, the R\u0026amp;D team reduced the sensitivity of this BA driver through the shell design and other methods. This ensures that the BA and electrostatic drivers output their respective frequency ranges without interference from each other – resulting in the two drivers working together in harmony with a smooth overall frequency response curve.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"FiiO FX15 Internal Structure\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/Capture.png4.png?v=1694447272\"\u003e\u003c\/p\u003e\n\u003ch3\u003eRigid yet flexible Giving your music soul\u003cbr\u003e10mm DLC dynamic driver\u003c\/h3\u003e\n\u003cp\u003eThe FX15 features a 10mm DLC dynamic driver, chosen for its high rigidity, high damping coefficient, and other positive attributes – allowing the driver to deliver a robust, full sound that manages to be both highly detailed yet pleasant to listen to. And in order to achieve harmony between the dynamic, BA, and electrostatic drivers, the R\u0026amp;D team specially redesigned the structure of the dynamic driver, leading to a coherent sound from the bass to the ultra-high frequencies in the FX15’s frequency response curve.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e“In the development of the FX15, we wanted to let the electrostatic drivers be the star of the show when reproducing sound. The sensitivity of a single balanced armature driver is 110dB. If we use multiple BA drivers, the frequency response range that the BA drivers cover will be even more prominent, overshadowing the other drivers. In other words, using too many BA drivers will not allow the listener to truly experience the brilliance of electrostatic drivers. Thus, we decided to employ one BA driver and four electrostatic drivers per ear.” --Allen, Chief Expert Of FiiO Audio R\u0026amp;D Centre\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eFree of cerebral biases \u003cbr\u003eInstant AB Electrostatic on\/off switch\u003c\/h3\u003e\n\u003cp\u003eWe have added a switch that specifically turns on and off the electrostatic drivers, allowing the listener to instantly AB between having and not having the drivers.

At the heart of the S.Turbo design is a lengthened low-frequency sound tube that effectively filters high-frequencies produced by the dynamic driver, so that the sound of the bass dynamic driver and mid-to-treble balanced armature driver are smoothly connected and do not interfere with each other for optimal sound quality.\u003c\/p\u003e\n\u003ch3\u003eExceptional sound Painstakingly crafted\u003cbr\u003eHi-end specially-tuned frequency response curve\u003c\/h3\u003e\n\u003cp\u003e\u003cimg alt=\"Frequency response graph for FX15\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/7891047copy.jpg?v=1693935845\"\u003e\u003c\/p\u003e\n\u003ch3\u003eDelicate sound Reminiscent of gingko beauty\u003cbr\u003e“Sound and Form” harmonic design\u003c\/h3\u003e\n\u003cp\u003eThe FX15 is a highly resolving IEM that is more than capable of reproducing sound frequencies above 15kHz.

The FX15’s shell is made using the advanced DLP-3D printing method with printing accuracy down to 0.0375mm, ensuring that each FX15 shell is accurately molded to ensure highly consistent sound between every unit made. In addition, the FX15’s shell is made of photosensitive resin, which features high impact resistance, providing robust protection for the electrostatic and balanced armature drivers.\u003c\/p\u003e\n\u003ch3\u003eErgonomic triangular design\u003c\/h3\u003e\n\u003cp\u003eFiiO not only considers the shape and materials used for its IEMs, but also whether they are actually user-friendly.
