K5 Pro Gaming DAC Headphone Amplifier Mini Hi-Fi Stereo Digital-to-Analog Audio Converter USB Type C/Optical/Coaxial to RCA/3.5MM AUX for PS5/PC/MAC/Computer

I was looking for a good quality DAC/amp to game with. Something not complicated by software. Came across this and I am very satisfied with the sound and quality build. I use it with the Dolby Atmos audio and Razer's THX Spatial audio app...and wow...I get the immersion that I was looking for. I owned this for a couple of months and has had no issues, no static nor dropped audio ( others may be having issues due to computer overclocking, as OC also strains all components on the mobo.) I have been using this with my EPOS H6 Pros ( open and closed back) and can say this DAC/amp really brings my headsets to life. Music is also detailed and well separated with plenty of volume. This can handle headphones/headsets up to 300 ohms, anything over and it will struggle, but I knew this when I bought it. I primarily use it for gaming and I am very satisfied. Get it for what it is, a basic stereo audio DAC/amp. If you get it and try to make it work for what it is not, don't complain about it and try to make it out as a bad product. Turning it on is straight forward, hold the volume knob in for a few seconds and off you go. If you are going to connect this to a USB hub, make sure that it is powered, it does use a bit more power . I recommended this to friends and family and have yet to hear any complaints.

I have an Edifier T5 subwoofer connected to a pair of R1280Ts. When connected directly to the computer's 3.5mm output, the subwoofer was uncontrollable - it shook the house no matter what I did to the volume, EQs, whatever. I had to basically turn it off. Now, I run a USB cable from the PC to the K5, and RCA cables from the K5 to the subwoofer, and more RCA cables from the subwoofer to the speakers. After setting the low-pass filter on the subwoofer to just over where the speakers drop off, the sound is crystal clear with bright highs and thrumming lows (without dominating the whole sound). The fact that I can instantly control the bass and treble on the K5 is a huge plus. I am thrilled with the K5, and it was a very cheap solution to get the most out of my not-so-cheap speakers. edit: Okay so its not PERFECT. This is going to take some explanation. If you're planning on using powered speakers on a PC, this applies to you. Everything was fine until my GPU (RTX 2080) came into play (firing up a game). The computer began sending a ton of interference down the USB connection to the F5. More expensive units I'm told can filter this out, but the K5 can't. Now this isn't necessarily the K5's fault. Computers are electrically noisy, and if I replaced my PSU, motherboard, GPU, or all three, that might solve the issue. Since that would be insane, I instead opted to power the K5 through a source other than the PC (outlet will do fine) and use the optical input (toslink) for data. Since toslink uses light to transmit the data, it is immune to EMI interference. Perfect sound. The only downside is my audio is running through my Realtek onboard audio again now; which I'm not thrilled with, but really isn't a problem. If you're using headphones, this probably won't be an issue. And again, this really isn't a knock on the K5, they do say they're for headphones and not powered speakers (probably because they don't have the electronics to filter out the type of noise I'm describing), but if you're planning on using this device for speakers, just a heads up on the USB audio combined with a powerful GPU. On a final note, I did hack a USB cable, cut the power/gnd from the PC and connect that to another USB cable going to a separate power source. It did eliminate the GPU-related noise, but the PC was still noisy enough to introduce interference somehow (ground loop possibly? Doubtful since all power came from a single UPS). They do sell USB galvanic isolators, that might do the trick, but they're as or more expensive than the K5 itself. Optical connection will do fine. Edit2: turns out it was my speaker's issue with the aux input. I bought a separate speaker for my work computer and now I just do a direct USB connection to my computer and all interference is gone. I'd still prefer a separate power input from the USB data input in case you ran into interference from the motherboard, but I have 5o say it's perfect now

I bought this expecting “good enough.” What I got was a little metal brick that basically killed my urge to upgrade. Setup is instant — plug in, Windows recognizes it, no driver drama. Build feels solid, real volume knob, separate bass and treble that actually work (not gimmicky). Sound: Bass is tight and controlled, not bloated. Korean R&B and EDM hit hard without turning into mud. Mids are clean, vocals feel present, and the treble is crisp without stabbing your ears. Gaming: Footsteps are super easy to place. Imaging is way better than it has any right to be at this price. Power: Drives everything I own with headroom, zero hiss. If you just want clean power, good bass, and no headaches — the K5 Pro is great value

This little amp is the perfect addition to a nice pair of hifi headphones. I thought the 3 small metal knobs would be pretty gimmicky but I turned out to change my mind in practice. Sometimes I will be playing a game where theres just too much bass in the mix and I'm having trouble hearing footsteps, so I just turn the knob down halfway and voila, perfect mix again. Same for movies and tv shows but in reverse. I have a pair of Philips shp9500 and so if I am watching a tv show, I usually just crank up the bass just a little bit to give it that 'oomph' feeling. The amp overall can push up to 300 ohms and it gets way too loud for me, it would damage my ears if I turned it all the way up. The build feels great, its smaller than I thought and I actually like that. Its this little chunk of metal that just outputs great audio.

situation : malentendant, j'ai un casque filaire MEZE 105 Silva, avec un cordon DAC qui me permet, en le branchant sur le téléphone d'avoir une écoute améliorée en liaison avec le logiciel "amplification" d'Android. Mais pour la TV, c'est plutôt plus compliqué. TV SAMSUNG 65 TQ65S95D avec platine extérieure et ses connexions. J'ai commencé avec un SENNHEISER RS195, bon casque, connexion optique, mais le volume son est limité. Il me fallait donc une solution pour brancher la sortie optique de la TV sur un ampli DAC avec réglages séparés (aigus, basses, volume) sur lequel, je brancherai mon filaire. J'ai donc soumis chatgpt 5.2 à la question et après un prompt indiquant qu'il était important que je puisse entendre les voix correctement (problème de phonèmes), il m'a proposé 3 articles possibles, en me donnant un avis : sur l'utilisation réelle, la puissance, le rapport/qualité prix et ce modèle est sorti en 1er de son classement. J'ai donc essayé et le résultat est parfait. Je peux ainsi choisir en même temps l'utilisation du casque en vue : - d'obtenir le son du HP TV si une personne regarde une émission avec moi - idem pour le son de la barre de son SENNHEISER notamment pour le Dolby ATMOS (le Fosi ne prend en charge que le PCM sinon, ça ne fonctionne pas) ou le casque seul en optique. Ainsi, je maîtrise les réglages. Le FOSI est petit, il a des connexions en câble optique, en RCA et en coaxial. L'alimentation se fait par USB C 5V (ce qui correspond à la norme standard) Une seule réserve : les boutons de réglage me paraissent "fragiles". A voir dans le temps. Attention, on trouve ce matériel un peu à tous les prix ça va de 65 € environ à 145 euros, mais j'ai préféré choisir le fabricant plutôt qu'un illustre inconnu en terme de fournisseur. Rapport qualité/prix : bon Note globale : 9/10 - je recommande selon usage et déplacements

Excelente. lo conecté al puerto USB C, también trae adaptador para USB A-B, sin problemas. De inmediato se encendió. conecté el rca a mi amplificador. y ualá: Agudos finos, pensé que mis bocinas no daban eso, y sí , el DAC funciona! Se oye el fondo de cada instrumento, los instrumentos en sí usan un amplificador Monoaural, y se mezclan. Este DAC te deja notar ese detalle. Lo he probado con buenas mezclas, se nota la diferencia desde el primer momento. Es calidad de sonido. Para los que apreciamos la sutileza del sonido. apenas me llegó ayer, y es genial. aún falta probar lo en otros aspectos, pero por ahora, se nota en calidad de sonido. los aqudos son puros, transparentes. Se nota el DAc, de inmediato. lo uso con un amplificador fosi BT 10

Barato , cómodo y útil. Aparato bien construido y con sonido muy aceptable.

The packaging comes with optical, USB-C/A cable, 3.5mm jack splitter for mic and headphone. The DAC is well built just like other Fosi products, solid gunmetal aluminium enclosure. Front: All the aluminium knobs feel high quality. The tone controls have a midpoint tactile stop. The volume control uses a Taper-A pot, which also serves as a power and input switch. Back: The USB-C port was slightly offset and the connector was a bit difficult to insert. Consider enlarging the hole for the USB-C port on the backplate a bit so that the connector doesn't rub against i How does it sound? First, I compared the K5 Pro to the onboard audio on my Asus B550A motherboard (SupremeFX S1220A), which is already pretty decent. However, when I played games, the motherboard produced a ton of coil whine noise that originated from my GPU. The DAC completely eliminated the coil whine noise when I used both the optical and USB modes. As far as sound quality, I couldn't hear any difference between the S1220 and the K5 Pro when I used a QC25 headphone. I also tried switching between the optical and USB modes to see if I could hear any difference, but there was none. Some people don't like the tone controls because they affect the sound quality, but I found them very useful for adjusting the sound to my taste. I often tweak them depending on the content I'm listening to. The playback bitrate of 96kHz works with USB, and 192kHz works with the optical. I didn't test the Coax input because I don't have one. The maximum microphone recording bitrate is 1 channel, 24bit, at 48kHz. Room for improvement: I suggest keeping the naming short and just including the model and brand name, like the TB10D. No need to print the entire 'MINI STEREO GAMING DAC' on the front. It would be useful if the device could remember the last input mode when there is a power loss, as well as the last power mode. For example, if the device lost USB power while it was on, it should turn on again when the USB power is restored. Consider enlarging the hole for the USB-C port on the backplate so that the connector doesn't rub against it.
