FiiO FX17
Advanced Driver Architecture
The FX17 is built with an innovative per-side design featuring one dynamic driver, four custom balanced armature (BA) drivers, and eight high-performance electrostatic (EST) drivers. A meticulously tuned five-way crossover evenly distributes energy among all drivers, ensuring each component operates at its optimal state for a grander soundstage and natural, lifelike audio reproduction.
Electrostatic Driver Innovation
Eight carefully implemented electrostatic drivers per side deliver an exceptionally airy high-frequency extension—easily reaching up to 50kHz. Although their inherent sensitivity is only 99dB/mW (compared to the typical 110dB/mW of BA and dynamic drivers), the FX17’s design employs multiple electrostatic units to increase sound pressure levels. This strategic approach overcomes the natural “masking effect” (the ear’s reduced sensitivity to high-frequency sounds in the presence of powerful low frequencies), ensuring that the high and ultra-high frequencies are not only audible but also richly detailed.
Custom Balanced Armature Excellence
The FX17 features four custom Knowles BA drivers that are innovatively split into composite units—each composed of a dedicated mid-frequency and a mid-high frequency section. This “Midrange Enhanced Balanced Armature Unit,” developed in close collaboration with Knowles, incorporates acoustic vents within the ear cavity to boost sound energy reserves. The result is denser mids and sumptuous, transparent vocal reproduction that places the listener right in the heart of the performance.
High-Fidelity Dynamic Driver Performance
At its core, the FX17 utilizes a dynamic driver with a lithium-magnesium alloy diaphragm—a material that is both lightweight and exceptionally rigid. With a density of just 1.6g/cm³, this diaphragm demonstrates high internal damping, minimizing intrinsic resonances and keeping distortion below 0.2%. The result is pristine sound reproduction even at rapid vibration speeds, ensuring unmatched clarity and dynamic precision.
Patented S.Turbo Acoustic Design
Inspired by high-performance turbo designs in supercars, the FX17’s patented S.Turbo acoustic structure channels sound through a uniquely shaped pathway to dramatically enhance bass output. This design not only boosts deep, robust low frequencies but also effectively filters out superfluous mid and high-frequency signals from the dynamic driver, facilitating smooth and powerful transitions across the audio spectrum.
Optimized Acoustic Architecture
The FX17’s resonant back cavity has been refined with precision-engineered vents (diameter: 0.2mm) that control airflow and achieve an ideal balance between the dynamic driver’s front and back cavities. This advanced design enhances the driver’s overall performance—the dynamic “O factor,” amplitude, low-frequency extension, and mid-frequency clarity—bringing a balanced and immersive listening experience.
Dual-System Five-Way Crossover Precision
Taking the performance a step further, the FX17 integrates an electronic and physical dual-system five-way crossover. This design guarantees smooth frequency responses, a flat impedance curve, and balanced energy distribution, even at varying volume levels. Notably, unlike earlier models with toggle functionality for electrostatic drivers, the FX17 increases the number of these drivers to reduce power requirements while ensuring they are a critical component in handling wide-ranging high frequencies.
Ergonomic Nozzle and Fit Enhancements
Extensive user feedback and scientific studies have led to a precise 10° adjustment of the sound nozzle relative to the ear canal, ensuring that the drivers align perfectly for enhanced comfort and stability. A reengineered 3D-shaped back cavity features a 1.4mm thick ear-conforming filling that secures the in-ear monitors (IEMs) more naturally, while a reduced thickness in the folded-screen area minimizes pressure on the ear, resulting in a truly comfortable and secure fit.
Premium Mixed Cable Construction
The FX17’s cable is engineered using a synergistic blend of gold, silver, and copper. Each element is forged at temperatures exceeding 1000°C and undergoes secondary refining to form pure crystalline monocrystals. This process minimizes impurities and transmission loss, allowing the cable to harness the unique acoustic properties of each metal for a significantly enhanced overall sound quality.

FAQ's
How long does it take to process an order?
For in-stock products, your order is expected to be shipped within 3 working days. Customized items and pre-orders take a longer time (do check in with our staff for more information). On normal non-sale days, once your parcel is shipped:
- For Standard Shipping, it takes about 2-3 weeks for items to be delivered after it is shipped. For some countries, it might take up to 1-2 months, depending on your country and its custom procedure. The duration for transit is beyond our control. Mechlands does not arrange refunds for such cases. Please consider an upgrade to DHL Express or keep the waiting time in mind.
- For Express Shipping, it takes about 3-10 days for items to be delivered after it is shipped.

Shipping methods and period might be affected and changed due to festive seasons, pandemic circumstances or other unforeseen circumstances.
What kind of shipping do you offer?
We have two shipping methods - Standard Shipping and Express Shipping.
Standard Shipping is free for most countries/areas.
Express Shipping via DHL Express or FedEx is 10-40USD (excluding tax) depending on your country. If your order is over 500USD, DHL Express Shipping is free*.
*KiiBOOM keyboards are not eligible for free shipping.
Shipping fees exclude import taxes or processing fees that may be applicable for your country. Mechlands is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the two-way freight charges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.
Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Mechlands will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.
For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments. Should you have any other queries regarding shipments, please contact us before placing an order.
Who does pay for the import tax/custom fees?
Customers have to bear any form of custom/import/processing fees that are applicable for your parcel.
If the custom fees and the delivery of the parcel are rejected by the recipient, the shipping cost still needs to be paid. Mechlands only arranges the refund of the order amount after deducting the shipping cost incurred.
Which countries do you ship to?
We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. Shipping methods may alter due to different situations. After proceeding to Checkout, the available shipping method(s) and cost will be stated before the payment page.
