FiiO K5 Pro Headphone Amps Portable Desktop DAC and Amplifier 768K/32Bit and Native DSD512 for Home/PC 6.35mm Headphone Out/RCA Line-Out/Coaxial/Optical Inputs

I recommend it for just about anyone that is looking for a solid midrange budget dac/amp. Build quality feels good. The knob has a really good feel to it. You know that nice level of resistance so it doesn't get accidently spun but not to spungy to annoy you. The switches have a nice tactile feel to them so it's easy to tell which setting they are on and when they click between positions. Comes with all the cables (power and usb) you need along with headphone connector adaptor So you should be set if your 2.5 or 3.5. It also looks pretty clean. Easy to tuck away but not an eyesore on your desk if it's in the open. It also pushes my 150 ohm cans to perfection so I believe them when they say it can drive up to 300s. I have been fooled by other dac/amps in the past but that is not the case here. It drives what it says. Very clean sound. I do recommend getting the actually drivers from FiiO's website to get the best out of them on your PC though. It won't be as clean without them. So remember to do that if that is important to you. But if you just plug it in windows will detect it and you will have sound if you don't feel like messing with it (cannot confirm with an apple). But really does it all pretty well. Music, movies, and gaming are all satisfied to level you expect for the product. I know you will see a few cheaper ones and I would recommend you pass them up for this one. Its great. I believe to really get better you are going to have to almost double your budget and start to enter the realm of entry professional level equipment.

I was quite surprised that the sound reproduced through this unit was very clean and had such clarities. Sound signature is very neutral and transparent with good sound stage. This unit also has a respectable and powerful amp section too. Maybe on par with Schiit Magni or JDS Atom in terms of power. You could crank up the volume all the way and no audible hiss was present. This can drive pretty much any headphones out there with ease maybe except for a couple very hard to drive planar headphones. This is absolutely a bang for the buck and in my opinion better than Topping dx3 or Aune XS1 as a Dac/Amp combo. One thing I did not like about this unit was the volume control. Depends on songs I listened to, I could hear a very little static sound when adjusting the volume. I don't hear it when there is no music in the background, but especially when there is a quiet song playing, the static sound was audible. If you are looking for the one solution desktop Dac/Amp combo with outstanding performance that does not hurt your wallet, this is it. I highly recommend this.

This is my first FiiO product purchase, I bought it to replace a $400 DAC/AMP from Sound Blaster that started failing after three years. ThIs FiiO while costing far less than the amp it replaced, sounds surprisingly clearer and more dynamic. I've got it running a pair of Beyerdynamic DT 880 headphones, and they've honestly never sounded better. The highs are just a bit on the bright side, but to me that's a positive. The mid range seems neutral, without being overly flat. And the bass is pretty impactful and would probably be even better on more bass heavy headphones. The build quality shames the product I had before it, which was made of thick plastic. Where the K5 Pro is made of aluminum, my cats have even knocked it off my desk once so far, and it didn't even hurt the paint job. Very impressive! I also use the line-out to a Sony 2 channel amplifier, which together powers a pair of Klipsch Reference Premiere speakers that run from my Desktop PC. I've not noticed any distortion or issues from the DAC while in use, not on the headphone out or the line-out. However, my one complaint would be that you cannot toggle between headphones and speakers, you must either turn off your speakers or unplug your headphones. While I'd like to see a toggle switch for this, perhaps on a future model. I'd still gladly recommend this product and look forward to FiiO's future offerings!

I have yet to review this on my YouTube channel. However, after months of use, I can say the Fiio K5 Pro is an excellent option for those on a tight budget or who simply need a smaller amp/dac. Fiio's sound signature has changed over the years. I find some of their gear rather harsh sounding. I expected the K5 Pro to be harsh as well--to accentuate treble and/or have noticeable grain. Surprisingly, the K5 Pro is rather neutral and does NOT have harshness or grain. There are more expensive units that might provide a bit more detail and resolution (and, of course, there are MUCH more expensive alternatives that do indeed provide noticeably more detail and resolution), but for personal use, the K5 Pro is quite easy to listen to. There should be no mistaking the K5 Pro. It is not a product for professional use. As I said above, if you plan to use this in a recording studio, you might not be impressed. But those who want an affordable option for casual use, the K5 Pro does provide an uncolored sound. The build quality is also very good. Everything I can see and touch on the unit is made of metal. The volume knob doubles as the on/off switch. It turns smoothly. There is no channel imbalance at lower volumes--an achievement indeed, considering far more expensive alternatives still suffer from this. The connections are plentiful, and you can easily switch between those options by flipping a switch on the front. The K5 Pro does not need drivers for Mac OS. It is plug and play, and was immediately recognized on my Mac laptop. On Windows, however, there is some confusion. Fiio uses a unified driver for all of its USB dac devices. You can download this driver from the Fiio website for Windows. When you plug the K5 Pro into your Windows computer, Windows will try to set up the device. At first this works fine; you might even be able to connect to the K5 Pro. But if you turn the K5 Pro off after successfully using it on Windows, and then a few moments later turn it back on to use again--Windows 10 will not recognize it. I have tried different USB cables, and plugged the unit into powered and unpowered USB hubs, and different USB ports on my computer--with no change. If you turn on your Windows computer, log into Windows, and THEN turn on the K5 Pro--Windows likely will not recognize it. This issue has been documented online for Fiio's other devices, and there are one or two comments about the K5. Uninstalling and reinstalling the Fiio drivers does not solve this problem. It is entirely possible there is an issue with the USB on my particular unit...but the fact that the K5 Pro works perfectly with Mac OS leaves me to doubt this potential explanation. The only workaround I have found is that I turn on the K5 Pro and THEN turn on my Windows computer. When I log into Windows, the K5 Pro is recognized and I can connect. However, if I turn off the K5 Pro and turn it back on, Windows won't recognize it. This can be a fairly frustrating experience for those who leave their computers on but turn off amp/dacs between use. There is no indication that Fiio has any intention of fixing this problem. As I said, this might be a bug in a few particular units, and yours may not suffer from it. However, it is important to keep this in mind nonetheless. Overall, the K5 Pro is an excellent option, and the USB bug on Windows is quite odd...it may not happen to you, and even if it does, what I do might also work for you.

I consider myself a beginner audiophile. I just started getting into high-end audio equipment. This is my first purchase of a DAC/AMP. I do not do any professional audio work so I didn't really need anything too fancy. I mainly bought this to use for casual music listening with my high-end 80-ohm Beyerdynamic headphones. I currently have this hooked up to my desktop computer using an optical SPDIF cable. I do notice an improvement in sound quality with this amp compared to just having the headphones plugged directly into my PC. With the headphones connected directly connected to my PC they sounded somewhat muffled, but not with this amp. - The separation is better (sounds "wider") - It brings out more detail (I am able to hear sounds in the music that I never heard before). - The sound seems crisper and cleaner and there is noticeably less distortion - Better bass, more punch - headphones sound more equalized and better balanced. - louder sound The only thing is that this does not seem to make much of a difference in sound when using the analog line in ports. Although I do love the flexibility of having all of the options available. It seems like the best way to benefit from this device is to use the SPDIF or USB input since they are digital (although I have not tested using USB yet). The only thing is that it cannot be powered from USB without using the AC power supply like other DACs, but that is not really that big of a deal to me since I will not be using this on the go. I will have it sitting on top of my PC tower all the time. This DAC isn't really made for portable use anyway due to its size. I would say I made a good choice with this purchase as it seems to suit my needs.

Completely new to the audiophile scene but I figured I would give my thoughts. There's a review on here (Amazon) by the author "Keep it real, Brigham" stating the same as me and I completely agree with him. I ran this with a pair of HD660s (150 ohm if you're unaware) and I honestly couldn't tell much of a difference compared to plugging them directly into my motherboard. I'm running a ROG STRIX Z270-I and it drives them perfectly. Max volume, when plugged into the board, is uncomfortably loud. I hear zero hissing, distortion, or crackling and it still sounds just as clean as the K5 Pro does. I'm assuming my board must have some decent onboard audio based on the results I'm hearing. Specs say it can allegedly drive up to 600ohm headphones. I'm trying everything from FLAC files, MP3's, and video games such as PUBG/CS for footsteps. I'm just having a hard time finding differences between plugged into my board vs. using the K5 Pro. The only difference I can say unequivocally is that the K5 Pro will drive them to a level, such louder then my board, where I just don't see the point because it's painful. My 2016 Macbook Pro on the other hand cannot drive my 660s and the K5 Pro does an excellent job at bringing my cans to life in that aspect. But my needs reside at my desktop so I will be returning. In closing: I really just don't have the need for this AMP/DAC at the moment but I still give it five stars all the way around. Highly recommend to anyone who abusively has the need for it and doesn't want to break the bank. Don't forget to install the Firmware on Fiio's website once you get it all hooked up!

Outstanding value for the money. Not the most powerful, or clean amp or the best DAC chips but a good value as a package at the low MSRP. The volume control illumination is good looking and the big control is cool and ergonomic. I will say the plastic dial does not feel as high quality as the metal casing. The whole unit is very light weight too so it’s easy to move around. Nice hardware switch for source. I am using the optical and usb inputs and switching between them is fairly reliable. On a few occasions in a month of ownership my Mac won’t reconnect after waking but that experience isn’t consistent and may be an issue with the Mac. Sound quality is good but maybe not mind blowing. I have some high end Focal headphones and Audeze planar dynamic headphones and both sound detailed and fully powered by this unit. I have heard better but not on anything I personally own. For the price it’s a great all around package!

Let me start off by saying I'm not an audiophile. I'm using this to drive a pair of ATH-M50x's - a pair of headphones famous for not needing that much power to drive at only 35 ohms of impedance. Believe it or not, the cheapy ear buds Apple used to include with ipods measures at 42 ohms but I digress. However, the audio quality coming out of this is - to my untrained ears - leaps and bounds better than the realtek audio on my motherboard. It's even better than the "built-in headphone amp" from my Creative SoundBlaster Z. The reason that I actually bought this is because I had issues with the creative software. changing from speakers to headphones kept crashing the software and I was getting annoyed by the fact that with each update, it still wasn't fixed. So I went to the output of my onboard realtek card. It was OK, the soundblaster was a bit better. So I bought this....and It's working great. Not only is the sound better but when I turn on the amp, the speakers automatically mute! Windows just knows to output all the sound to my headphones. This is great if i'm taking a call or chatting on discord with my boom-mic. I no longer have to futz with Creative's awful software. That along is worth the price of admission. Plus music sounds better now since I can up the bitrate thanks to this. Downside, the massive collection of MP3s i've "acquired" over the years sounds awful now. Oh well!

Estaba escéptico respecto al uso de un DAC externo, pero viví años en el error. Definitivamente este dispositivo mejora notablemente la reproducción de mis CD, su desempeño fue igual de bueno utilizando como transporte de CD un reproductor BluRay Sony, lo utilicé también con un dvd player marca Harman kardon, y tres diferentes C D player (Yamaha y Onkyo).

Pour ce prix là, j'espérais bien un produit de qualité. Résultat : pas déçu, au contraire. Le produit est bien fini, semble solide tout en étant assez léger, ne glisse pas sur des surfaces en bois, le contour qui change de couleur en fonction de la source d'entrée est bienvenue ! Niveau connectique, on peut se régaler : il y a de tout ! En plus, beaucoup de câbles sont livrés avec : un USB B - USB A, pour connecter aux PC compatibles, et profiter ainsi du DSD. Aussi compris : un jack 3.5 vers 6.35, alimentation aux normes européennes, d'autres patins anti-glisse, c'est très sympa de leur part. Maintenant on approche du plus important, la qualité sonore et l'amplification. J'utilise cet AMP de deux manières différentes : avec un DAP, le shanling m2s branché avec un câble USB C vers USB B, ou avec le PC. - Résultat : avec mon DAP pas vraiment de différence de qualité d'écoute, mais la partie ampli fait très bien le job (je vais revenir dessus), et sur le PC, ça change la vie lors de visionnage de films ou d'animés de qualités. - J'utilise pour l'instant cet ampli avec un unique casque : le beyer DT 880 Edition (ver. 600 ohms), assez difficile à driver en temps normal, mais ici rien qu'avec le réglage d'ampli le plus bas et la molette à fond, le niveau sonore est très raisonnable, et si je monte au niveau 2, c'est largement assez fort pour quasiment toutes les écoutes, et au 3ème niveau seulement sur les rares morceaux qui sont pas assez forts de base, ça reste peu fréquent de monter jusque là. Et malgré ça je ne rencontre pas ou très très peu de distorsion (ça dépend du fichier sonore, en mp3 ça va forcément grésiller atteint un niveau sonore, dès le flac 16 bits, ça devient plus dur de rencontrer de la distorsion, et à partir du flac 24 bits et DSD impossible à moins de mettre un niveau sonore pas supportable par nos oreilles si sensibles. Donc pour résumer le produit fait totalement le job ! Je connaissais déjà la marque Fiio mais ce produit rst digne de confiance en tout cas pour l'instant. Soyez sûr que j'éditerai ce commentaire si jamais il arrivait un quelconque soucis !

Used this DAC for my TV setup. TV > DAC via optical cable > DAC to Speakers via RCA cables. Kept experiencing dropoff via optical, no issues via USB. Swapped optical cables & still same issue. Swapped the DAC out for the WiiM Pro Streamer DAC, issues resolved instantly. Based on the troubleshooting, it seems to be an issue with my particular unit, via the Optical Cable input on the DAC. This DAC is also extremely lightweight, the build doesn’t feel that great. But easy to setup, just plug & play. Frustrations only came in via the faulty optical cable input.

Absolute beast, does the job for my Sundara closed back planar headphones with multiple options for connectivity.

O produto é fantástico! E ele merece 5 estrelas! Cumpre bem o que promete, e funciona tranquilamente no Linux! O problema é que recebi um produto usado, sem fonte, com arranhões e marca de queda!! Tive que comprar uma fonte no Mercado Livre para poder usa-lo, com medo de danificar o produto! Pelo valor que gastei, e sem resposta do vendedor, não consigo dar mais estrelas!
