When you have an IEM inspired by FiiO’s flagship, you know you can only expect the best. Introducing the FD3 Pro in-ear monitor. This IEM ensures hi-res audio with minimal distortion thanks to its high-quality 12mm drivers. Its sound tubes and cable terminations make it customisable based on your audio preferences and source device. All in all, the perfect IEM for your music needs.
Great Music Starts Here
Experience high-resolution audio with minimal distortion with the FiiO FD3 Pro. This IEM consists of a powerful driver with a lightweight Diamond-Like Carbon (DLC) diaphragm, ultra-fine copper-clad aluminium Japanese Daikoku voice coil and a strong magnet with a magnetic flux of 1.5 Tesla.
Music that’s Certified Hi-Res
The FD3 Pro comes with an all-new DLC diaphragm that’s incredibly rigid and light. This makes it ultra-sensitive with minimal distortion. An acoustic prism system completely removes the problem of time delay caused by the sound wave propagation path in the cavity by eliminating the high frequency standing waves, enhancing overall sound wave diffusion. This leads to incredible sound quality and a Hi-Res Audio certification by the Japan Audio Society.
Add a Human Touch to Industrial Precision
FiiO is all about bringing industrial precision with human craftsmanship together, and the FD3 Pro is no different. The main body is engineered from a 5-axis CNC-processed aluminium-magnesium alloy and later hand-polished. A 2.5D glass coating adds a beautiful look to the sleek curves.
Choose your Sound
Listen to your music, the way you want with the FiiO FD3 Pro’s interchangeable sound tubes. Enjoy detailed treble with the large inner diameter black tube or go for an incredible bass with the smaller inner diameter red tube.
No Pressure for Long Listening Sessions
The semi-open design is based on the patented technology for balanced air pressure. It protects your hearing while ensuring a natural sound. Based on this technology, the air pressure in the housings is balanced which leads to reduced pressure on the eardrums and in turn lesser fatigue.
Connect to a Device of Your Choice
The FD3 Pro comes with an exclusive high-purity monocrystalline silver-plated copper cable. This cable consists of 8 strands of 19 Litz Type 2 wires each, i.e. 152 wires braided together for a rich audio experience. The interchangeable plugs (2.5mm, 3.5mm and 4.4mm) allow you to connect to a source device of your choice.

Pros: 1) Wide soundstage
2) Upfront, Bold and Dynamic Sound Signature

6) Lots of useful accessories in the package

To Note : My review is strictly for Fiio FD3 Pro and strictly based on my use with Hiby R3 Pro Saber DAP. FD3 Pro was brought with my own money and hence the review is completely my own unbiased thoughts
I have recently brought a Fiio FD3 Pro and paired it with Hiby R3 Pro Saber Dap (through 2.5mm balanced port).
The sound that came out of the FD3 Pro through my set up was big, bold, energetic and detailed to keep it simple . I used the stock red tubes with small vocal tips and also tinkered a bit with MSEB tuning in the Hiby. However, I never touched the equalizer.
The mids of the FD3 Pro (through my set up) was forward, warm and lush. Bass was punchy and strong but never overpowering the other frequencies (as was your experience through the stock nozzle) . The treble was smooth yet still detailed but not sibilant. Some of the best music I enjoyed through the FD3 Pro were music with large amounts of instruments (orchestral music mostly) and also energetic pop songs. As far as soundstage is concerned it is more wide than deep. I could easily distinguish between extreme left, left, centre image, right and extreme right. Imaging within the soundstage was pretty good as well.
Edit: I tried the black tuning filters. They made the sound too bright for me
Some tracks I listened to
1) AR Rahman music (Mudhalvan, Alai Payuthe, Jeans etc)
2) Durum - Kate Linn
3) Casanova- Allie X
4) Beat the Devil's Tattoo - BRMC
5) Animals - Maroon 5
6) Sgt Peppers Lonely Hearts Club Band - Beatles
