Description

Description

Design & Build Quality

The FT5 represents FiiO’s entry into the flagship planar magnetic category, emphasizing a balance between acoustic rigidity and wearer comfort. The chassis is constructed from a specialized magnesium aluminum alloy, a material chosen for being approximately 36% less dense than standard aluminum while maintaining the structural integrity required to house a large-format driver. This choice of metal significantly reduces the total weight—addressing a common complaint with planar headphones—while providing a superior damping environment that resists the vibrations generated by high-energy playback. The open-back architecture features a scientifically tuned grille designed to precisely control airflow, enhancing treble transparency and spatial imaging.


Engineering & Performance

At the core of the FT5 is a 90mm planar magnetic driver featuring a 6µm ultra-thin diaphragm. To drive this diaphragm with surgical precision, FiiO employs 20 N52 neodymium magnets per channel (40 total) with a magnetic density reaching 1.5 T. These magnets are placed in a balanced array—11 on the interior and 9 on the exterior—to ensure the aluminum-silver alloy coils are suspended in a perfectly uniform magnetic field. This symmetry minimizes diaphragm "breakup" and ensures that the driver moves with absolute phase coherence across the entire frequency spectrum.


Connectivity & Integration

Recognizing the diverse needs of modern audiophiles, the FT5 is engineered for seamless integration across multiple platforms. It features a high-purity, 392-wire silver-plated monocrystalline copper cable that ensures lossless signal transmission. The standout feature of the cable assembly is the interchangeable plug system, allowing users to switch between 3.5mm and 4.4mm terminations instantly. FiiO further expands this utility by including 6.35mm and XLR-4 adapters, ensuring the FT5 can interface with everything from a mobile DAC to a high-end balanced studio amplifier without requiring third-party cables.


Listening Experience

The FT5 offers a unique sonic profile for a planar headphone, characterized by a rich, authoritative bass response that is often missing from this driver type. The large 90mm surface area moves a significant volume of air, providing a physical sense of scale to orchestral pieces and a visceral impact to contemporary recordings. Users can further tailor the experience with the two included earpad types: the suede pads offer a warmer, more atmospheric sound with vigorous bass, while the protein leather pads provide a more clinical, detailed presentation with a wider perceived soundstage.
 

Who This Product Is For


The FiiO FT5 is designed for the audiophile who seeks the speed and transparency of planar magnetic technology without being tethered to a high-wattage desktop amplifier. It is an ideal choice for home listeners who value a wide, immersive soundstage and those who transition between dedicated listening rooms and mobile high-fidelity setups. Its robust metal construction also appeals to users who prioritize long-term durability and industrial-grade build quality.

 

Frequently Asked Questions
 

Do I need a powerful desktop amplifier to use the FT5?

No. While the FT5 scales beautifully with high-end gear, its high sensitivity of 110dB/Vrms means it can be driven to excellent levels by most modern portable high-resolution players and portable DACs.

Can I use these headphones in an office or public space?

The FT5 uses an open-back design, which means sound will naturally leak out to the surroundings and ambient noise will be audible to the wearer. They are best suited for quiet, private listening environments.

What is the difference between the two included earpad types?

The pre-installed suede pads provide a "warmer" sound with a more vigorous, atmospheric bass. The protein leather pads offer a "clearer" sound with enhanced detail and a wider perceived soundstage, allowing you to tune the headphones to your preference.
