Fosi Audio Q4 - Mini Stereo Gaming DAC & Headphone Amplifier, 24-Bit/192 KHz USB/Optical/Coaxial to RCA AUX, Digital-to-Analog Audio Converter Adapter for Home/Desktop Powered/Active Speakers - Black

Mp3s ruined music. Those who grew up on cassettes and CDs know that music is supposed to sound a certain way. However, those who have only heard Mp3s may not fully understand. Even with low-quality headphones, cassette tapes and CDs provide an immersive listening experience. In contrast, listening to old favorites on iTunes can be dull and lacking in detail. I used to focus on expensive Bluetooth headphones that promised an excellent listening experience, but found that the sound remained unsatisfyingly uniform. Eventually, I discovered the Hifi realm and realized that streaming services offering Mp3s had been scamming us. All I needed was a DAC and a pair of affordable headphones, along with a Hifi subscription from Deezer, to experience the full range of amazing sounds again. I am now listening to my old favorites again and they sound as they did on CD Those who claim that DACs don't make a difference probably grew up on Mp3s. Although it's not necessary to spend a lot of money on this equipment, I found that my DAC headphone combo cost a third of what I paid for my Sony XM4s and provided much better quality. The only downside is that this setup isn't portable. However, it works well for me as I'm mostly at my desk. I just started using this DAC so I can't give a comprehensive review of it. I can tell you it works well and sounds amazing. But I bet an audiophile may laugh in disgust. If anything happens in the coming months I'll update here.

Very good product. Don’t expect a very deep bass or any sound profile on mediums and highs. It is a plain, neutral DAC. And for that, it does an excellent job. I liked the construction, the materials quality and the accessories that came with it.

Average product

Typical expat living shared accommodation...you need to give privacy of your house mate ..having this device it gives you that privacy with a bass on the heaphones (edifier brand) with a kick on it ..listening music as it is using your PC Or Loptap ..

this product just works.

The audio quality for a product worth 350 dhs was not great, the packing was horrible

Ho acquistato questo prodotto senza troppe pretese, visto che la maggior parte di accessori simili supera abbondantemente i 100€, primo perchè è la prima volta che acquisto un preamplificatore DAC per cuffie e secondo perchè ho delle cuffie da 150€ ma mi sembrava eccesivo spendere più soldi per un convertitore, visto che il 90% della qualità sonora ricade sugli altoparlanti. Il prodotto, pagato poco meno di 56€, se considerato che è completo anche di un cavo di collegamento USB e di un cavetto ottico oltre che del cavo di alimentazione (sempre USB), svolge bene il suo lavoro. Accetta in ingresso segnale ottico, coassiale o USB, mentre in uscita dispone di collegamento jack 3.5 frontale e RCA nella parte posteriore. Sempre nella parte frontale troviamo il selettore sorgente ingresso e 3 manopole per regolazione bassi, alti e volume/accensione, oltre una spia rossa che ne indica l`accensione. Presenta in uscita un suono pulito con assenza di distorsione in cuffia alzando il volume, per quanto mi riguarda promosso a pieni voti se vi interessa ascoltare musica in formato FLAC dal vostro pc, se invece utilizzate pc solo per giocare ed ascoltare musica in formato MP3 non noterete alcuna differenza. Unica nota negativa il manuale in dotazione praticamente inutile, non tanto perchè solo in inglese, ma perchè scarno di informazioni sulle caratteristiche tecniche e le immagini si riferiscono solamente al DAC -Q5 PRO.

Bonjour ! J'ai fait l'acquistion de ce DAC Ampli car la carte son intégré de mon pc ne me permettait pas de profiter correctement de mon nouveau casque, le DT 770 Pro. J'ai commencé mes recherches en ayant aucune connaissance dans le milieu de l'audio, pour être honnête, je ne suis pas plus avancé à l'heure qu'il est mais, mon budget et mes critères m'ont amené à ce produit. Beaucoup d'avis internationaux, beaucoup d'avis assez incomplet, c'est pour cela que je vais essayer de faire de mon mieux pour vous décrire le produit. La première chose à savoir est que l'alimentation du DAC se fait via un cable micro usb, cela m'a déstabilisé au début, le câble USB-MIDI ne servant qu'à faire le lien entre le DAC et l'appareil utilisé (ici mon ordinateur). L'installation sur mon PC s'est fait automatiquement : une fois branché, le driver s'est installé automatiquement et mon pc l'a reconnu. Niveau connectique du casque, c'est une entrée Jack 3.5mm. Il y a 3 modes réglable via un petit "levier" : USB, Optique et Coaxial. Ne connaissant et n'uitilisant pas les deux derniers, je vous donne uniquement mon avis sur l'utilisation USB. Le produit en lui-même a selon moi un aspect assez qualitatif, finition en métal, les différents boutons sont solides et agréables à utiliser. NIVEAU SON maintenant, c'est là où mon manque d'expertise va entrer en jeu malheureusement, je ne pourrais pas vous donner d'aspects vraiment technique sur le rendu du son etc, je vais donc juste vous faire un comparatif entre l'utilisation de mon casque avant de faire l'acquisition du produit et une fois le produit acquis. Mon casque a une impédance de 80 Ohms, mais la carte son intégré à ma carte mère (Asus TUF B450M Plus Gaming), n'était clairement pas suffisante pour pousser le casque correctement : le son était très faible, il y avait des petites interférences, assez rares mais assez embêtantes avec un casque de cette qualité, le son saturait rapidement malgré un niveau de son en dB assez faible... et le son paraissait très étouffé. Une fois le DAC Ampli installé, sans même toucher aux boutons permettant de régler les basses et les aigus, le rendu audio s'est métamorphosé : - Son beaucoup plus clair, plus net; - Volume très puissant, réglable facilement via la "molette" de volume qui par ailleurs est très agréable à utiliser; - Le correcteur de tonalité (ajustement des graves et aigus) joue vraiment beaucoup dans la plus value de ce produit selon moi : il offre un très bon rendu, vous permet d'ajuster vos écoutes selon vos préférences et le type de musiques écouté; - J'ai enfin pu découvrir les basses de mon casque qui ont un rendu vraiment prenant. Conclusion : Je ne suis pas audiophile pour un sous, mais j'adore écouter de la musique, et ce DAC Ampli combiné à mon casque m'ont fait re découvrir des musiques que j'écoute depuis des années. C'est la première fois de ma vie que j'ai l'occasion d'écouter de la musique avec une qualité pareil, ce sont les petits détails qui changent toute l'expérience. Je ne peux que recommander ce produit au vu de son prix, sa qualité et ses fonctionnalités. Le seul "inconvénient" (qui n'en est pas un pour moi) du produit peut être l'alimentation, qui se fait par Micro USB. J'espère avoir pu vous aider via cet avis, ceux qui sont dans ma situation et qui cherchent un DAC Ampli pour driver un casque sur PC notamment, foncez !

After losing five $20-30 headphone amplifiers in a row, within days or weeks, just because we're tripling the cost here doesn't necessary mean this will do better. In the q&a section one person warned me it died within two months, another person says it's been running for two years. Why a solid state device should have any life is beyond me, my beloved 50+ year old Nakamichi RE-3 receiver is still running fine. My question was, since this does not have a 3.5 audio input, can it be fed by a PC into the coaxial input with a converter? Four people said yes, one said no. It's no. So, what use is a 3.5 to coaxial conversion plug? Never mind. Since I cannot get my Dell running Windows 10 to put any sound into this through the USB route, it's useless, to me at least, as a PC headphone driver. One of the days I suppose I should get the headphone jack fixed, it's dead for some reason. Still working on that, the last headphone amp I had died, so my PC is going through the Nakamichi for awhile, rather clumsy. I also need an amp for my new Vizio TV. It also has a 3.5 audio out, forget about that. Therefore, I hooked up the optical input, and nothing, no sound at all. I checked all the connections, seemed to be okay, but just before I ripped it out to send it back to Azon, the darn thing turned on. Is there a warm-up delay?? It will be on all the time, so hopefully it will keep running. One other slight problem, the cords are absurdly too short, the optical cable isn't even as long as my TV. No biggie of course, but if you're going to put cords in the box, at least make them long enough to be useful. So, I'll live with this for awhile, and then edit the review . . . one way or the other. Ed: One thing, normally I set the volume control at about 75% on everything, and adjust the volume to my earphones through an in-line control. When set like that, I was picking up sputtering sounds on some Youboob videos, but it was fine on video files played from a USB stick (the only two ways I use the TV). Youevil volumes are much higher than typical USB files, I knew that, and the USB files play fine. I was not picking up any problems on my PC, so I switched out everything, the in-line volume wheel controls, the earphones, both combinations, and it was definitely something in the TV audio. I turns out I had the volume set waaaay too high on the Fosi box, with the in-line control taken out, the headphones were blasting. I played around with the volume knob, and lo and behold, the sputtering sounds went away. I had to fine tune it so the in-line control had enough room with both Eviltube and USB sources, which worked out to be around 55%. If you're having problems, you might try turning it down. Note, the variable audio output on my TV does not work if you plug in something to the optical output, so unless you want to get up off the couch every 30 seconds to adjust the Fosi volume, in-line controls are a must for my setup. They're very cheap, but buy them by the handful, they wear out. They work very well with YT when you run into a commercial, you can cut the volume to zero instantly. Ed: I'll bump it a star, for two reasons. First, the original unit I bought is still alive, and in the headphone amplifier world, that seems to be a real accomplishment. And, I bought another one for my 2015 Vizio, now relegated to the bedroom, and it fired up and worked as well, on optical. So now I have two of them, and I'll see how long they last. Maybe someday down the road this will get the final star. Also wik: Two months now, one is on 24/7, the other with the second TV off and on. No problems. That should be long enough for any glitches to show up. Update: Over two years now, it's on all the time, and it still works.

Prima voor de prijs. Mijn koptelefoon klinkt niet best als ik deze direct aansluit op mijn laptop. Uiteindelijk gekozen voor dit apparaatje. Wat een verbetering! Ook kan ik nu mijn favoriete nummer op een hoger volume afspelen.

Lo use para conectar la tv a un estéreo sony genezi fst-2000, la tv al fosi audio q4 lo conecte a través del cable óptico y luego del dac fosi q4 al estéreo sony genezi vía rca. El audio mejor notablemente y lo mejor fue que se se pudo ecualizar los agudos que es el motivo principal por el que adquirí este equipo ya que el sony fst-2000 daba un sonido de audio con graves muy fuertes, con este equipo solucione mi problema de los agudos y se escucha muy bien. Ya puedo ecualizar la música a mi gusto graves, agudos y volumen. Recomiendo este equipo si lo buscas para un propósito similar, su diseño es pequeño cabe en la palma de la mano es bueno porque no es voluminoso y cabe en cualquier lugar para instalarse, los materiales son robustos y de calidad. Como fuente de energía utilice la entrada usb de 500mA 5v de mi tv y levanto sin problema al equipo dac fosi q4.
