Review: Good well rounded IEM - 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.
Review: Beautiful sound, audiophile bass - Amazing IEMs, not just for the money but in general. I own many “audiophile” headphones and these compare with the best of them. I wanted something with lots of clear and defined bass, while retaining detailed mids and crisp highs, and these deliver. I use the red sound tubes and vocal tips because they are the most comfortable and give the best, most reliable seal, which provides the best bass and sound in general. If you can EQ, then cutting out some 2.5khz and to a lesser extent 5.5khz frequency gives an even smoother high-mid/low-treble sound, as they have peaks in that range that can become a bit tiresome with certain songs. I also add a low shelf (bass boost) for some types of music and they can handle it like a champ. However, even without EQ they sound great although a little bright, but with the many different tips and sound tubes they’re customizable enough. Great value for the money I recommend to anyone who wants better sound than what even the best bluetooth earphones can provide, casual listeners and “audiophiles” alike.

## Features

- [Flagship-level DLC diamond diaphragm, for an amazing, powerful sound]: The FD3 headphones benefits from the numerous advantages of FiiO's new dynamic driver. The diaphragm is made of Diamond Like Carbon (DLC) which is both impressively rigid and helps to reduce unneeded distortion yet also surprisingly light, allowing the driver to have excellent transient response. The result is a driver with excellent sound quality and minimal distortion with the added bonus of being ultra-sensitive.
- [Flagship-grade acoustic prism, take your breath away]: The acoustic prism so effectively used in the flagship FD5 for great sound quality is also featured in the FD3. Like with the FD5, the acoustic prism system brings numerous benefits such as eliminating high frequency standing waves, enhancing overall sound wave diffusion, and even effectively solving the problem of time delay caused by sound wave propagation path in the cavity. This all leads to marvelous sound quality.
- [Better sound with semi-open design,makes you less tiring and the sound less forced]: The semi-open design of the FD3 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.
- [2.5D film coating glass faceplate] 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 FD3 exceptionally light, making it easier and more pleasurable to carry around. And the aluminum-magnesium alloy main body is made in an industrial process combining five-axis CNC processing and hand polishing.
- [Well-equipped just for you] The well-received interchangeable sound tubes also make an appearance on the FD3, The cable adopts an expanded MMCX connector for easier cable changes; the curved audio plug design makes it easier to plug into; and 4 strands of high-purity monocrystalline copper wires for a total of 120 wires make your music and vocals simply vivid.

## Questions & Answers

**Q: Can these be worn down or just over the ear?**
A: Mine arrived with what appears to a permanent coiling of the wire just before the earphones, as though they're intended to be worn over-ear. I prefer not to wear them that way. Although the coiling makes that just slightly awkward, it's still quite doable.

**Q: Can these be used with an iPhone13?**
A: Of course, but you need a lightning to aux dongle.

**Q: Does is has a mic?**
A: No mic with these earphones..

**Q: Can I use  the FD# with an Android phone?  Do I need an adapter?**
A: These headphones have a 3.5 mm TRS (phono) analogue audio connector.
if your phone does not have a 3.5 mm jack, then you will need an audio adapter (probably USB-C)

### ⭐ Extremely Regrettable Purchase
*by R***N on November 12, 2025*

There's a lot of issues with these earbuds, but first the pros: - Nice holder case for it and all the spare parts - Extra speaker parts to replace - Lot's of ear options - A few extras in the case - The sound is pretty nice for the most part, when it works. And now the cons: Out of the box left ear didn't work. Switched the ear piece to the spare and it worked fine. Then the right ear stopped working a few weeks later. Switched to the spare no issues... Or so I thought, but I would regularly find that they unscrewed themselves constantly so I would have to search around for that spare until I eventually lost it outdoors because it wouldn't stay screwed in. So I went and started using the original and have been having a ton of issues. For one, the audio just cuts out randomly or starts going static. I think there's something wrong with the wire as out of the box I had issues where if I pressed a particular part of the wire it would stop working - Now it's the opposite where I need to press it for it to work. Also can't get them to stay in my ears but that might be more of a me issue. The audio quality is inconsistent, its louder in one ear than the other... I could go on. I've had an absolute nightmare with these. They are NOT worth $150. Very unfortunate that I basically threw away $150.
