FIIO FH3 HiFi Earphones 3 Drivers (1 Dynamic + 2 Knowles BA), in-Ear Earphones High Resolution, Bass Sound, High Fidelity for Smartphone/PC/Tablet

Soy musico de profesión, y evidentemente utilizo bastante los in-ears para los eventos. Vengo de utilizar KZ, he probado varios, los ZS10 los ZSN, ZS10 Pro y etc. Definitivamente estos son muy superiores, en lo personal noto que su sonido tiende a ser mas bien plano, no exactamente plano, pero si se acerca bien a este sonido plano el cual es bastante util para un musico, los comparé con mis monitores (Unos Presonus Eris 3.5) y la verdad que el sonido es bastante similar, lo cual me sorprendió para bien.Así mismo puedo decir que algo bastante especial es la claridad del sonido, ya que con estos a diferencia de en los KZ, se puede apreciar mucho mejor cada uno de los instrumentos tanto en canciones y en especial en los eventos en los que estaba tocando. Cierto es que para escuchar musica día a día depende del gusto, ya que como bien se sabe, el sonido plano es mas bién opaco, y así percibo estos fiio fh3, y un pequeño hueco en las frecuencias alrededor de los 500hz que marca el fabricante si se llega a notar, aunque no es problematico para mí. Por lo cual, para escuchar musica estaría bien, aunque si te gusta mas el sonido brillante y con presencia en los medios, quizá no te termine de convencer. Pero como digo, para eventos en vivo, como monitoreo, me parecen excelentes y en especial por el precio, me sorprendieron, puedo escuchar con claridad en mi mezcla 3 voces (Principal y 2 coros) Guitarra (Mi instrumento), Bajo, Batería (el kit completo microfoneado), instrumentos secuenciados (multitrack), metrónomo y voz de guía para algunas canciones, y pude escuchar todo en su sitio, nada se chocaba con nada, podía entender claramente que hacía cada quien, por lo cual, definitivamente son una excelente opcion si los piensan para monitoreo en vivo.Por ultimo, son muy cómodos, no son especialmente pequeños, ni tampoco son grandes, tienen un tamaño mediano tirando a pequeños, y he podido estar casi una hora con ellos sin ninguna molestia, el cable es bien maleable y es lo necesariamente largo, se ajusta bien a la oreja y no se caen con el movimiento.En conclusión, me parecen excelentes en especial para uso profesional (Performance en vivo, incluso mezcla). Para uso diario como digo, tienden a ser planos, y pues es entendible que ese sonido plano no sea lo más agradable para ello, ya que por lo general agrada mas el sonido con buen brillo y demás adornos, entonces puedan gustar más o menos, pero no me cabe duda de la claridad, si o sí se pueden notar bien los detalles de cada instrumento que se reproduzcan.

(update: early on I had slight driver flex when adjusting them while fully in my ears but nothing unusual or annoying. at about 2.5 months in and the driver flex is almost non-existant after a few hours use each week. Everything seems to sound the same but I suppose it broke-in a bit)More sensitive to tip selection than I've experienced before. Tip selection can go from excessive bass boost to a more neutral bass/treble boost and in between.the provided tips won't let you tune it very much, but this is my experience with a handful of tips:-Spinfit 145: slightly-too-much boosted bass (still clean but too much mid-bass)/somewhat subdued treble.-Narrow bore (eg. Final Type E) - less bass than Spinfit but still a few dB above neutral bass / neutral treble (not my preference forget exactly which tips did this, but narrower bore than Spintfit 145/KZ Starline so under ~4-4.5mm.)-included widest bore tips / shorter-wide bore - sub-bass boost, mid-bass a bit less than "narrow bore" above, and slight treble boost.-KZ "Starline" tips (newer revision is actually soft/usable) might have given me my favorite tuning: boosted bass but less mid-bass than Spinfits, and a slight treble boost).Tips don't seem to effect mids/upper mids enough for me to consider them due to the bass/treble tuning being affected so much. Upper mids can get a slight glare depending on the tip but at it's worst I have to be looking for it during tip comparisons.The way Fiio has done the venting is also very consistent with the bass tuning, the other sets listed below that have inner vents are very inconsistent based on how the inner vent is/isn't blocked.some differences with my 2 best sources: (Shanling M2X / Fiio Q1 [not MK2])Using these from PC USB - Fiio Q1 or Shanling M2X line out - Fiio Q1 is the best sound i've found with these and has me agreeing with the more stellar reviews these have gotten. I don't normally use my Fiio Q1 since getting the Shanling M2X but in trying it out of curiosity when I first got the FH3 , i found they sounded better when powered by the Q1.Running these from my Shanling M2X they lose soundstage and are a bit closed in sounding, everything loses a bit of definition, bass loses some of that great speed and and seems to gain a bit of messy mid bass. just worse sounding all around, soundstage, bass speed/detail, treble detail and energy. I couldn't say exactly why this is happening but the Q1 advantages are: a lot less output impedance (0.3ohm vs 1.0ohm) and quite a bit more power headroom (190mw - 32ohm vs 106mw - 32ohm). High gain on the Shanling M2X seems to alleviate the issue a bit, but hard to say because the difference when using the Fiio Q1 is obviously noticeable when A/B testing but the M2X high gain setting is not obvious. I may order a balanced cable to see what happens with more power out of the M2X.I can see some reviews leaning more negatively if they experienced what I'm getting from my Shanling M2X, it honestly doesn't sound amazing, but still good for the price. Out of the Fiio Q1 I find myself agreeing with the more excessively positive reviews out there.--Original review notes--less of a review, more just a couple notes about what i was concerned with before purchaseIf you're like me, I'm used to more V or U tuned iem / earphones and was worried this would be too bass light due to some reviews but this has as much bass as others i'm used to (tip dependant) such as ZS10 pro, TRN v90, mh755, 1more Triple.this seems to be thanks to the upper mids and treble tuning not being elevated like my other sets, so i can turn this set up a bit more overall.Most of the tip selection provided runs a bit small, i would call the largest tips more of a medium or in between med/large, 1 set of the 9 included tips is a larger standard size (short, wide bore). since the nozzle diameter is a pretty typical size my narrowest and widest bore tips work well enough to not slide off.

Awesome IEM for the money! Sounds just as good as IEMs twice the price. The midrange is full and slightly forward but not shouty...great for male vocals. The bass is excellent...very punchy, controlled and accurate. The highs are clear and not fatiguing whatsoever. Overall an excellent IEM for a 1DD-2BA configuration. This is my go-to set when Im on the go and out and about.
