Fiio K1 Portable Headphone Amplifier&DAC and USB DAC, Titanium

So I've used it on a Nexus 6p, and Linux mint. Both went without a hitch. I'm using Sony MDR7506 over the ear headphones that I've been driving with a cmoy headphone amp. My first toe into better audio quality. I was blown away by the sound. But when i used the amp and headphones on my lenovo laptop it sounded crazy better than the phone. So I went looking and came across this DAC/amp. It worked instantly on my 6p and sounded fuller than the 6p with just the cmoy. It doesn't have as much power as the cmoy does but it has enough to drive the MDR7506 60ohm's to an uncomfortably high level for most apps. And regular hear buds will blow your ears out. I tested the power draw it was between 20 and 40 milliamps depending on the source YouTube vs pumping music. So I wouldn't think there would be a big hit on the battery. On the Lenovo running Linux mint I had to do a reboot before it would work right. Which I don't know if that was needed for the DAC or if I really just needed to reboot because I haven't done so in a maybe 6 months. I couldn't tell any difference in sound quality on the Lenovo between the k1 and the cmoy amp. The Lenovo seems to have a pretty good DAC on board. But it was much better than running the headphone's straight from the headphone jack without an amp. Bolder more dynamic I think it's what the audiophile's call sound stage. The real winner is portability. This makes using over the hear headphones a real possibility here it was a bit silly. Car trips, airline travel, hell it's portable enough to use while grocery shopping. If you have a 6p get it and also get this 1 foot type c to micro USB cable.http://www.amazon.com/gp/aw/d/B014QK6WRE/ref=mp_s_a_1_2?qid=1456028728&sr=8-2&pi=SX200_QL40&keywords=1+foot+type+c+to+micro

This thing is so simple. For anyone interested I can confirm this works great with an iPhone 6s Plus using this cable:  Lightning to MicroUSB Cable, 6'' black,for connecting DAC/Digital Camera to iPhone 7/Plus/6/6s/Plus/SE/5s/5 & iPad Normally this device would require the Camera Connection Kit (CCK) to work properly with an iPhone because most Lightning to USB cables don't have the ability to carry power and this amp is powered by your phone (it does not have it's own internal battery). Also this device uses the micro-USB connector so that would rule out any "normal" Lightning cable anyway.That would be the only Con: that your phone drains faster when using this, and you can't charge your while using it because it's using the Lightning port already.The headphones I'm using:  HIFIMAN HE400i This amp drives them wonderfully with a full rich sound and no need for any EQ in my opinion. I tried all the built-in EQ settings in the iPhone and it sounds best with the EQ turned off. However, I can turn this all the way to max volume without hurting my ears. My normal comfortable listening volume is 2 or 3 clicks below full. So this amp is just enough. For less efficient headphones or for those that want it REALLY loud, you may want to get a slightly more powerful DAC/AMP. Maye the FiiO Q1 although I haven't researched how much more powerful it is. The Q1 would also solve the phone battery issue as it does supply it's own power and you can disable it charging from the USB to keep it from draining your phone.

This WILL work with just about any Android 5 and higher device. However, this does require a POWERED hub.Now the question is, who makes a small/battery powered USB hub. If you are looking for a smartphone DAC thatis all in one, just go with the Fiio Andes or other battery powered DAC.Note: Installing USB Audio Player might make your audio stop working. Uninstall, turn OFF your phone completely and power back on to restore USB audio functionality again.Tested with: VLC player and HibyMusic they both sounded really good, although the Hibymusic Equalizer is superior, the VLC EQ sounded much flatter and lifeless. My USB Audio Player trial only crashes on my Moto X. Did not try on my Kyocera since it does not run a late enough version of Android. I will test further with my nVidia K1 tablet and a modified Nexus 7 tablet.I only tested with my Shure IEMs, I will bump it another start if I think the sound quality warrants it. It will not get 5 stars from me because using it with a mobile device requires a rather cumbersome setup.

Voilà maintenant plus d'un an que j'ai acquis le Fiio K1 après que le port jack de mon Fiio Q1 ce soit cassé (modèle plus chère). Autant dire que je ne suis pas déçu, j'ai eu beau le faire tomber à maintes reprises, le laisser traîner n'importe où, il est toujours comme neuf. Il est donc très résistant et bien conçu malgré son poids léger.Quant au son, je le trouve meilleur qu'un Fiio Q1 qui m'a couté pourtant deux fois plus cher environ.Le DAC me permet de profiter de toute la puissance de mon Casque Sony MDR-1A qui en plus d'amplifier la puissance sonore, améliore la qualité du son en rendant la musique plus spacieuse et aérée.De plus, le plug-and-play rend l'utilisation du DAC très simple, il n'y a rien à installer.Clairement un achat que je ne regrette pas, vous pouvez foncer les yeux fermés !

For Android Users:I've recently decided that my onboard audio just doesn't cut it for my OnePlus 5T and Bose QC 35 II headphones. So I went for this, expecting a nice, entry level step up in terms of power and clarity, which is exactly what I got. I mainly use it with my laptop and my desktop computer, so it's nice that it's so easy to move, even though some will certainly miss the smartphone compatibility. Hence bought a USB type C to Micro USB cable to work with my 5T too.If you're used to more expensive amps, you may not be super impressed. But bear in mind that these employ the same audio chip as FiiO's E17K, which cost about three times as much. So in certain use cases, like mine, these are a killer deal! So, if you're just coming from system audio, you will notice definite improvements. I appreciate the tighter bass and wider soundstage these brought to my headphones.For iPhone users:This thing is so simple. Just plug and play. You don't need drivers unless you are using laptops/smartphonea from stone age! For anyone interested I can confirm this works great with an iPhones as well. Tested on 6/6S, 8 Plus, X and Xs Max. But to work with an iPhone you need to buy a separate cable.Normally this device would require the Camera Connection Kit (CCK) to work properly with an iPhone because most Lightning to USB cables don't have the ability to carry power and this amp is powered by your phone (it does not have it's own internal battery). Also this device uses the micro-USB connector so that would rule out any "normal" Lightning cable anyway.That would be the only Con: that your phone drains faster when using this, and you can't charge your while using it because it's using the Lightning port already.The headphones I'm using is Bose QC 35.This amp drives them wonderfully with a full rich sound and no need for any EQ in my opinion. I tried all the built-in EQ settings in the iPhone and it sounds best with the EQ turned off. However, I can turn this all the way to max volume without hurting my ears. My normal comfortable listening volume is 2 or 3 clicks below full. So this amp is just enough. For less efficient headphones or for those that want it REALLY loud, you may want to get a slightly more powerful DAC/AMP. Maye the FiiO Q1 although I haven't researched how much more powerful it is. The Q1 would also solve the phone battery issue as it does supply it's own power and you can disable it charging from the USB to keep it from draining your phone.This is decent go to USB DAC Sound amplifier. Do not expect your current sound would be amplified to a world class level, or some such powerful rich bass.

Den überraschend kleinen DAC/AMP kaufte ich mir über die Idee hinweg ein einen mobilen Verstärker zu haben dabei geriet auch der GGMM A1 in mein Visier, jedoch hätte die Enttäuschung über die Kompatibilität des A1 nicht größer sein können. Über Monate hinweg verwarf ich die Idee bis sie mir erneut in den Sinn kam. Diesmal jedoch eröffneten sich über eine Review des kleinen Fiio K1 ganz neue Möglichkeiten für mich. Kurzum habe ich ihn bestellt aber ob er sich beweisen kann ziegt sich im Folgenden:Verpackung und Extras. Verwirrt war ich, denn ich bekam keine Sendungsverfolgung lediglich einen Verweis zur deutschen Post. Die Erklärung kam mit der Lieferung. Die Verpackung war überraschen klein und dennoch erschien sie einem verschwenderisch groß für den winzigen K1, in Klarsichtplastik verpackt und mit einer kleinen Box it einem 5cm langem USB-Micro-Kabel und kurzer Anleitung."Buildquality". Beinahe phenomenal überlegt man sich das dieser kleine Schatz für unter 40USD in den Staaten weg geht. Geriffeltes Aluminium klemmt stabiles Hartplastik, der 3,5mm Aux-Eingang jedoch sollen spezifisch die Anschlüsse von Fiio schon vor Jahren überarbeitet worden sein (seit der Einführung des Fiio E10K Olympus 2). Etwas unbeholfen wirkt der Kleine jedoch dennoch, wenn ein dickes Kopfhörekabel an ihm hängt und er neben einer Tastatur liegt.Kompatibilität. Nun auch hier zeigt Fiio viel Arbeit geleistet zu haben. Viele DAC/AMP-Kombi sind zwar kompatibel zu Windows und seit Win 10 hat sich viel getan, dennoch hatte ich bisher keinen DAC welcher den Sound per Software regeln ließ. Das hat sich geändert, denn der kleine Fiio kann auch das und sogar sehr gut, dank vieler Win. Updates hat sich viel am Softwaresound getan und anstatt den sound zu komprimieren werden andere Methodn genutzt was dem Fiio zu gute kommt.Am Handy war ich ebenfalls positiv überzeugt denn auch hier macht nicht jeder DAC was er soll (GGMM A1 *HUST*) und genau deshalb bin ich überzeugt. Schließt man den K1 über OTG-Kabel an gibt Android eine Info und schwubs kanns losgehen. Der Fiio ist auch durchaus mit anderen USB-Micro-Kabeln kompatibel. die 5cm waren mir zum wohle des Aux-Ausgangs dann doch zu wenig.Sound, welchen ich nur wenig beschreiben will den für seinen Preis macht er einen tollen Job. Der GGMM A1 klang im Vergleich etwas zu hell und blechern (nicht ungewöhnlich, damit wird schlechter Bass verschleiert welcher bei billig DACs die norm ist) und selbst dem SMSL M3 macht er Konkurenz jedoch hat er nicht annährend die Power, muss er auch nicht. Den DAC des FX-Audio DAC-X6 schlägt er nur wegen des miserablen AMPs und der hohen "Output-Impedance" des DAC-X6. Der K1 klingt gegenüber den beiden am "kleinsten" und zeigt am wenigsten Bühne, der Teifton wirkt nicht überzogen und kommt auch bei bassstarken Hörern wie dem Audiofly AF100C gut und knackig rüber (Wichtig: kein Grundrauschen bei IEMs warnehmbar- hier verlieren beide Kontrahenten). Mitten, Stimmen sind mehr als Present und angenehm zu erleben, ja, doch wirklich ein genuß (in den Titel "Zankou no Terror - Von" hab ich mich aufgrund dessen wiederverliebt. Die Höhen leiden ein wenig an Detailmangel, hier merkt man die Preisdifferenz zwichen dem Fiio und SMSL, mit nierdig-ohmigen Kopfhörern ist es mit dem DAC-X6 jedoch schlimmer.Fazit, er bleibt, ach was red ich er ist schon Teil meines Rechners. Die Audiosteuerung über Windows ist einfach ein Feature welches ich nicht mehr missen will und genug Power für lautes Hören mit niedrig-ohmigen Hörern hat er auch und einen Beyer mit 250 Ohm kriegt er auch noch ohrenbetäubend laut ohne dabei am Sound zu versagen, bei dem Preis, der Größe und den Features warum nicht einfach einen Besitzen ?

No requiere drivers, por lo que en cualquier ordenador con windows 7 o posterior, es conectarlo y funciona (independientemente que tengas o no permiso para agregar dispositivos) Tiene un acabado solido y de calidad, y es ultraligero. La calidad, y sobretodo el volumen, se duplica o casi triplica respecto una placa base de casi cualquier equipo de sobremesa o portatil profesional. Yo lo utilizo con unos Bose AOE (triport originales) o con unos B&W p5 Series 1. y, configurando la salida del pc en 96bits, Calidad pura.

Rapporto qualità prezzo imbattibile. Il mio portatile, adesso è in grado di farmi ascoltare i file in modo molto gradevole, tramite il mio impianto stereo... la scena sonora è molto ampia e ben presente rispetto all’ambiente d’ascolto. La gamma bassa è ben proporzionata ( naturalmente se la qualità del file è molto buona) . I file di ottima qualità, fanno esaltare le doti di questo piccolo sorprendente DAC.Da comprare assolutamente per chi vuole godersi della buona qualità sonora. L’ascolto in cuffia è molto buono con una gamma bassa molto potente, però io ascolto molto raramente la musica in cuffia.Concludo dicendo che per quello che costa è veramente da comprare a occhi chiusi.
