It comes with two sets of tuning nozzles, one with a thin diameter of the mouth (red) and the other with a wide diameter mouth (black). 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). This cable sports a nice looking chin slider and Y splitter with a FiiO branding on the top that are made of metal material. The upper treble region of the FiiO FD3 is slightly less pronounced and detailed compared to the lower treble and upper midrange area. FiiO FD3 is just an exemplary example of such art, I admire him (or rather, before the people who did it).

FiiO is a high-end company designing products in China, and their offer is wide, ranging from Bluetooth receivers, DAPs, IEMs, Headphones and more. The faceplate of the monitor shell is one for sure one of the eye-catching highlights that the FiiO FD3 offers to the consumers.The semi-open design of the FD3 is based on FiiO’s patented technology for balanced air pressure within brings several advantages.

Fiios commitment to the end user experience shows as even their base model of the FD3 includes a premium accessories package that you would not expect.Instruments like pianos are slightly bright, pronounced and vibrant, while the brightness and intensity is increasing from the midrange towards the upper midrange. Pro model adds an upgraded silver plated monocrystalline copper cables in 8 cores with modular connectors.

The Fiio FD3 sounds more energetic and detailed in this area, especially when I do listen to soprano voices or instruments like cymbals. It fits right under the FH7, but above the FH5 and gets four drivers, delivering a slightly different sound signature, compared to the FH7 and FH5. The thin diameter nozzle benefits the lower end (more robust base) while the wide diameter nozzle benefits the high frequencies (more detailed treble) with the FD3 series.There is good width with tall heights but the stage depth is bit less, depth (-y axis) though is pretty good. 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.
