FiiO FD3

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.

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.

The sole qualm I have with these earbuds is a light static that can be heard when no other audio is playing, simulated tinnitus, essentially. That having been said, it's potentially a problem with my personal pair or the connection (I'm no audio professional nor expert.) Otherwise however, the fit is gloriously comfortable, the over-ear cable design was an interesting choice but it works well and the sound quality sounds better than most other audio devices I've tried. That having been said there is one clarification that needs to be said. Removable wires --DOES NOT-- mean optional wireless mode. It means that the earbuds may have interchangeable wires, as the only difference between the normal and pro versions are in fact - the wires. As far as wired earbuds go these are a 8/10 for me, would be 9/10 without the negligible static sounds when otherwise quiet.

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.

High quality high definition ear phone from Fiio China. Well done.

Incredibly clear and very rich sounds. I bought these a few week ago. They've taken some time to find the right fittings for my ears. The black and red fittings that come with the earphones will give you more bass, plus there are small metal filters that unscrewed from the earphones, they are the red ones, best for more bass. The vital thing is that the fitting is right for your ears to achieve the bass. I also use the equaliser on my samsung phone it works very well to adjust the required sound. They are the best earphones I've bought. I used to have skullcandy but these a red a big step up. One more thing the usb c connecter I'm using is a Hi.Dac 32 bit which I would recommend for these earphones. There are no controls on these.

Excellent casque. Pas de graves « inventés » (effet boum boum). Des aiguës de très bonne qualité, scène sonore large. Très confortable et léger (nombreux embouts fournis). Excellente finition. Assurément un produit haut de gamme à un tarif raisonnable. On regrettera juste un manuel un peu succinct.

Por más que vallas a buscar reseñas de profesionales en el audio, cada audífono tiene distinta firma sonora, cada oído tiene distintos tamaños, cada persona tiene distintas capacidades auditivas. Entonces, no se trata de ver cuál firma es mejor o peor según una persona que está en otro país, al final, en una semana te vas a acostumbrar a cualquier auricular. Aspectos como la amplitud sonora y la separación de instrumentos sí son características interesantes, pero audio "HiFi" se puede reproducir con audífonos de 20 dólares. Por eso digo, si te gusta el diseño, la marca y tienes el dinero, adelante. En el caso de estos audífonos, fueron los mejores que haya probado en la vida, el sonido me gustó bastante, fuerte y claro; los materiales se sienten premium, es una sensación que no se puede describir, el cable, el plástico, el metal, la caja donde vienen, me enamoré. Cabe resaltar que en un futuro me quiero comprar los FH7, y falta ver si esos serán mejores que estos para mí.
