FiiO FD1 Hi-Res Earphone Wired,Beryllium-Plated 1DD,4-Stranded High-Purity Monocrystalline Copper, 0.78pin,Strong Bass(Without Mic,Blue)

If you like a slightly V shaped sound signature with excellent detail, you won’t find many IEMs better at this price. In my opinion they are nearly as good as their cheaper cousin, the Jade Audio EA1 which I find to be more balanced. But honestly, these sound as good or better than many IEMs I have that cost well over $100.The sound signature is had a decent push in the bass and treble. Mids are rich and present with an excellent tonal quality you find from a good dynamic driver. To me, the measure of a good earphone is its ability to deliver bass that is strong and punchy, but not muddy; with highs that are detailed and have an air that gives spatial presence without getting harsh or sibilant. These do that very well, irrespective of price. Build is very good and can be worn comfortably for hours. If these were handed to me blind, I would have thought these were a more expressive product.Sound stage is decently wide left to right and provides a good sense of depth and space; especially considering the price. Detail is also good and coherent as you would expect from a dynamic driver. Overall tonality is quite smooth with a warm signature and robust sub-bass. But you still get the high frequency clarity of cymbals and triangles in both attack and decay. These have some of the best and natural highs I have heard at any price.While it is very good, there a few areas it misses. But not by much. One, the bass is a bit strong for the balanced frequency signature I prefer. Some will love the baas emphasis, but it’s a minor miss for me. Detail and imaging are good, but not on par with more expensive earphones; especially in the upper mids and treble. This may be a trade off for the warmer tonality. But something more expensive earphones manage to pull off.Very pleased these for the price. Hats off to FIIO on a fantastic product. They are proving that inexpensive Beryllium drivers can sound almost as good as TOTL IEMs that cost loads more cash. Get these before they go up in price.

I’m a certified basshead (that's what the doctor tells me : ), with an aversion to elevated spikes in the 4K range. The FD1 would classify as a 9/10, on the basshead metering system. There's always that 10th person that wants their teeth to rattle and there eyes to bulge.Like most DD only IEMs, the FD1 needs to be broken in. After playing back music on them (at a moderate level of volume) for 24 hrs, this is what I found:The FD1 addresses the frequency response range very well. From the sub 20 hz, to the upper regions, well into my danger zone. Thankfully I don't find the FD1 to be fatiguing.I wouldn't classify them as overly warm, like some find the very popular Blon BL03. If like me, you keep the BL-03 in your rotation, but you'd like an alternative with a rich sub bass, without a discernible amount of mid bass bleed, while maintaining of level of clarity for Instruments and vocals. then FD1 will do you right.ProsTakes to EQ very wellSub bass with authority,Clean mid bass,No discernible sibilance/hiss, that would cut my listening timeWide presentation,Vocals are well balanced, against instrumentsConsHoneymoon phase. I'll check back in, after a few more days of break in.I used a streaming service to test the FD1 against some of my test songs:1. “In the Air Tonight”, Phil CollinsOn most of my budget friendly IEMs the playback sounds pinched; on the FD1 It plays wide. That chorus of “Remember” is outside of my head.2. “When I get my hands on you”, Lost on the RiverThe sub bass is deep, with no discernible mid bass bleed.3. ”Yesterday”, BeatlesWhile the song has a minimal amount of instruments, there's great separation. Vocals are just in the right place, forward, but not dominating.4. “Hotel California“, Eagles (7:12 version)1st 30 seconds are impactful and clear, kick drum feels like you’re at a live concert. Vocals are spot on; especially considering the era that this song is from.5. ”House of the Rising Sun”, AnimalsThis is a song (as much as I like it) that I can’t normally playback at a respectable level of volume, without fatiguing my ears. No irritation to speak of.The included cable is one of the best that I've seen in the sub $100 category; I would have no qualms in using it, but I lean towards balanced cables, for my Radsone ES100. In the attached image, the clear tipped cable (on the left) is a 16 core KBear, with a TFZ/NX7 termination. As you can see, the KBear can sit flush to the shell, vs. the stock cable. In one of the Fiio diagrams, they point out that the base of the connection has a vent release. So if you choose to get a TFZ/NX7 termination, you can opt to leave a minute gap, for the vent.ETA: 72 hrs inThe FD1 hasn't changed. So unlike some offerings that suggest 100 hrs. of burn in, the FD1 is good to go in under 24 hrs. The width of the sound stage can not be understated; add to that an on demand sub bass, clear mids (devoid of mid bass bleed) and just enough sparkle to make you pause and you have an IEM that will please most.(cables again)Even though the FD1 and the FH1s would be considered Fiio's lower tier, the stock SE cable is the best that I've experienced in the last few years, for the sub $100 USD category. No need to immediately jump on the aftermarket options. But once you do, even an inexpensive balanced cable will increase the sound stage, for both depth and width. Night and day, no, but enough that the difference can not be argued.

I always like fiio products so this is a nice addition to my collection, great overall sound with a nice punchy bass, I use these with my fiio btr5 and they work like a champ will consider buying a balanced audio cable, my only complaint is that I did not order the black color, the case as you can see in my picture was clearly the correct one but the buds where black not blue, I'm not gonna return it but it was annoying

Cómo era de esperar el sonido es de excelente calidad todo muy equilibrado siempre y cuando utilices Tidal o Amazon music HD para poder diferenciar la calidad de la musica

Traen muchos accesorios (varios tips y una caja para guardarlos). Me gustó mucho el diseño de los audífonos, se ven muy bien y aparte el cable se puede desconectar en caso de que se dañe.En el audio se escucha bien pero no lo recomiendo tanto para géneros como rock/metal, con diferentes tips (gomitas) va cambiando un poco pero si lo quieres para ese género mejor busca otros audífonos o tendrás que ecualizarlos bien para que se adapten.Fuera de eso me parecieron buenos audífonos y solo se los recomendaría si lo agarran con descuento.

Remarkable pleasing sound for money. I have tried AppleAirpodsPro, SonyWF-1000xm3, BeatsStudio3, albeit all wireless, they all have tone issues, Apple mid heavy, Beats bass heavy, Sony had multiple EQs, nice feature but had distortion with high gain and horrible connectivity, AND are all more expensive. I bought the FiiO mostly for convenience as I listen seriously with my Sennheizer HD600s wired. And to my delight, I love the sound and gain. I have a dragonfly DAC/amp and don’t even need it with FiiO. Great product at twice the price!!!

Ich war 15 Jahre lang stolzer Besitzer eines UE 5 EB, damals in der 300 Euro Preisklasse angesiedelt. Ein Bassmonster mit phantastischem Klang. Ich betrieb diesen am Smartphone mit EQ auf flat.Nun brauchte ich Ersatz. Der Fiio 1 FD toppt den UE 5 EB in fast allen Bereichen. Bessere Auflösung und Räumlichkeit. Höhen und Mitten perfekt abgestimmt. Der Bass ist auf EQ flat wirklich ok. Mit leicher Anhebung toppt auch dieser der 5 EB. Die Reserven sind unglaublich.Guter Sitz im Ohr, für mich könnten die beiliegenden "Pröppel" etwas größer sein.Für den Preis unglaublich.....

Estos auriculares tienen un buen sonido, buena potencia y buenos bajos ,
