===============

1. 1.5T high magnetic flux - 12mm large size diaphragm

FD3 follows the core configuration of FiiO FD moving coil series, adopts a new 12mm flagship moving coil unit with large size external magnetic structure, releases a strong magnetic circuit of up to 1.5 Tesla, and uses Japanese large black ultra-fine copper-clad aluminum voice coil for surging power and extraordinary sound quality力，非凡音質。

2. Rigid and flexible - full-size DLC diamond-like diaphragm

FD3 benefits from FiiO's new dynamic design. The diaphragm unit is made of DLC-like diamond material, which effectively reduces the split vibration of the speaker diaphragm, reduces audio distortion, improves high-frequency extension and resolution, and is rigid and flexible.濟，纖毫畢現。

3. Precise Propagation - Flagship Precavity Acoustic Prism Device

After achieving remarkable results on the FD5, FiiO integrated the flagship technology front-cavity acoustic prism device as standard on the FD3, effectively solving the time delay caused by the acoustic wave propagation path in the cavity, adjusting the phase characteristics of the ultra-high frequency, improving the high frequency dispersion and eliminating the high frequency Standing Waves Increase Sound Diffusion Leapfrog Experience Starts Now越級體驗，現在開始。

4. Long listening without getting tired - semi-open acoustic back cavity

Based on FiiO's patented technology of balanced pressure relief in the front and rear chambers音來的更加輕鬆。

5. Arc Intersect - 2.5D blued glass panel

6. The original intention of quality, never stop

FD3 inherits FiiO's ingenious craftsmanship. The main body is made of aluminum-magnesium alloy. It is loyal to the original intention of high quality. The industrial production mode that combines five-axis CNC fine machining and full manual polishing technology is used. When the precision of machinery and the delicateness of handwork meet, unprecedented new heights of craftsmanship工藝新高度。

7. Diverse tastes - replaceable sound duct design The new generation of FD moving coil series flagship design's signature replaceable sound duct design has achieved good response on the FD5. This FD3 does not fall at all. The same standard replaceable sound duct design is in To achieve the same outer diameter of the sound pipe, FiiO designs different inner diameter sound pipes for replacement.聽，只為追求更高品質的你。

8. Pure arrives high quality wire材

In terms of cables, FD3 is FiiO's cutting-edge technology in all aspects. The headphone head adopts MMCX expansion cable interface, and the comfortable curved plug is designed to fit the cable body. 4 strands of high-purity single crystal copper material, a total of 120 cores are used for better vocal charm. Quality improvement is visible素質提升一耳可見。
