Instruments such like crash and ride cymbals do come slightly from the background, while their extension is a bit longer compared to hi-hats. DLC(Diamond-Like Carbon) is a highly rigid material that also has an extremely lightweight structure that reduces unnecessary vibrations and. Given their 32 OHMs of impedance, along with the 111dB/mW of SPL, you would expect them to be easy to drive, and they are. The midbass area of the FD3 shows a better sense of speed and authority, while it is also more impactful, which is especially audible in complex bass passages.

There is a bit of a peak around 5K which on the bass nozzles I find to be quite pleasant in imparting some energy into the otherwise warm presentation, but it can become offensive to some folks on the brighter treble nozzles.Packed with a single 12mm Berrylium-coated DLC diaphragm, a front acoustic prism, and a semi-open acoustic design, the FD5 looks like a high-end version of TinHifi T2 and T3. The result is a driver with excellent sound quality and minimal distortion with the added bonus of being ultra-sensitive. Mid-range and treble texture is superior, they sound fuller with finer articulation, more natural timbre and less rushed decay while although the soundstage is a tad airer and wider on the FD3, the FD5 takes a clear lead regarding the depth and overall holography. Following the FH5, you have the FiiO FH7, a 4-BA + 1DD IEM which shares the same shell as the FH3 and FH5, just in a different color tone.

I've been listening to FD3 for about two months before writing this full written review, and letting them do some burn-in, to offer them a fair chance to shine.The production of portable audio is no longer just a business, but rather a meaningful production of engineering, tactile and visual art. Fiio always seem to incorporate some type of treble spike in the treble tuning but this time around not so much. Owing to the overwhelming mid-bass experience, some of the bass on the FD3 PRO also tends to bleed into the midrange. The choice of cable is the only difference between the FD3 and the FD3 Pro: the standard model (which I received) includes a 4-strand single crystal copper cable with a 3.

FiiO FD3 Pro comes with a heavier, 8-strand 152-core Litz structure silver-plated monocrystalline copper cable with interchangeable termination plugs. Despite the semi-open design coupled with a vented DD, isolation surprisingly is still above average for me — and I never experienced any driver flex whatsoever. How do you please the huge dichotomy of enthusiast tastes in sound from a single tuning on an earphone. Think of it as the perfect blend of the FH7 and the FA7, but better: the sound stage is amazing, mids are great and all of that is neatly packed inside a cool 3D-Printed box of wonder.The unique celluloid panel is covered with Z5D film coating glass for a pure yet fresh transparent look And the aluminium- magnesium alloy of the body makes the FD3/FD3 Pro exceptionally light, making it easier and more pleasurable to carry around. Warm in definition, brightish in texture and thick in body, the low end is greasy and lazy, yet higly entertaining and not overly bleedy, it’s a big hit of chunk, not very flexible in articulation as some sub line will lack this organic fluidity and acoustic bass will feel slapped instead of offering a natural resonance. Thankfully in this case I did notice some improvement, which was further aided by switching to the wide-bore bass tips (despite the naming of the tips being somewhat counterintuitive here).

The FD3 comes with a Pelican-style hardshell storage case, three sets of S/M/L silicon tips (Balanced, Vocal, and Bass), two sets of medium memory foam tips, an MMCX tool, a cleaning brush, a set of treble tuning nozzles (in addition to the installed bass nozzles), and cable.The Acoustic Prism inherited from FD5 is fantastic at being a diffuser, and a passive filter, as we'll see in the Sonic Quality part of today's review.
