This is the non pro version. This is a good, well rounded IEM. I give it 4.5 stars. It is light and with the right size tip there is no comfort issues. It tends to be a bit on the bright side. Sound tube and bass tips tame it down to a good level. It delivers clean and crisp sound in all genres. The vocals and treble are very good. The bass benefits from amping. I use it with a portable amp (Fiio A5), with the bass boost on, and it improves the bass definition and power. I still feel the FH3 has a better more defined and beautiful bass. I was hoping they can reproduce that in the FD3.
Compared to the FH3, the FH3 was bigger and felt nicer sitting in the ear. However both are extremely comfortable. Also the FH3 felt a bit higher quality perhaps because of it’s design. The FD3 quality is very good, it’s just the feel of the FH3 was a little more upscale. The FH3 has a better more defined and cleaner bass, but the mid and upper frequencies were too thin with my equipment. It also has some weirdness in the treble of certain tracks especially acoustics. The FD3 has none of those issues. The FD3 has full bodied mids and highs, a little less detailed but still very good. With the 2 different sound tubes and the different tips you can dial the sound to the way you prefer, or to the genre you are listening to and it makes a difference. The basic cable is fine. I heard the pro cable may make the sound brighter. I don’t know how true that is. I wanted mine to be on the warmer side because the DAC I use tend to be on the brighter side. I had returned the FH3 about a month ago because I could not love the vocals and the treble. I will be keeping the FD3.
Update 11/25/2021:
I have upgraded the basic cable to a balanced cable. If you are not using a balanced output you are not getting the most out of the FD3. Despite using the 3.5mm with a DAC dongle and a portable amp the balanced cable was significantly better out of the DAC alone! Everything sounds cleaner and crisper. The bass is tighter, there is more separation, the stereo effect is noticeably better. So this lets me enjoy the music at a lower volume. For reference I am using a HIDIZS S9 (not pro) and Tripowin Altea 2.5mm cable which is a nice thick cable. I use the red sound tube with the bass tips and it balances out the sound pretty well. I think the sound tubes are a major selling point as you don’t to have to be stuck with one tonality.

Striving for perfectionThe aluminum-magnesium alloy main body is made in an industrial process combining five-axis CNC processing and hand polishing. The pin-point precision of machinery and the delicate touch only possible by human hands come together to create a phenomenal piece in the FD3 earphones. |
Form and function arc into oneThe FD3 headphones has a simple, yet beautiful appearance based on the theme of curves. The unique celluloid panel is covered with 2.5D film coating glass for a pure yet fresh transparent look. And the aluminum-magnesium alloy of the body makes the wired earphones exceptionally light, making it easier and more pleasurable to carry around. |
Better sound with semi-open designThe semi-open design of the wired earphones based on FiiO's patented technology for balanced air pressure within brings several advantages. Not only does such a design lead to more natural sound, but it also effectively protects your hearing by balancing air pressure within the FD3 leading to less pressure on your eardrums. This makes your listening experience less tiring and the sound less forced. |

Fantastic sound! Love them!
I bought these wired buds to listen to HD streaming audio (Amazon Music) powered by my Atom DAC2 and Atom Amp2. The sound is fantastic! I am not easy to please and these buds are keepers!
