Fosi Audio K5 Pro DAC Amp Headphone Amplifier, Mini Hifi Stereo Digital-to-Analog Converter, USB Type-C/Coaxial/Optical to 3.5MM AUX/RCA Jack, for Gaming PS5/ PC/Active Speakers Up to 24 bit/192 kHz

This little amp is a quality product, it arrives well packaged in a smart box with simple instructions and a selection of leads. The leads themselves felt a little bit on the cheap side but perfectly good for the task, I suspect most audiophiles would buy their own leads anyway. The amp itself feels very solid, with an all metal case (no cheap plastic here) that has a nice satin finish, it isn't going to win any style awards with its functional looks, but still manages to convey a pleasing aesthetic that isn't going to look out of place in any setup. The amp was very easy to install and setup, literally plug and play on my PC with no fussy drivers to worry about. It all worked straight out of the box, and it worked very well indeed! The sound is great, with no noise and very clear highs and lows. My onboard sound is pretty decent on my MSI X470 Pro, but I would compare it to the difference between listening to an MP3 and then a FLAC of the same song. Like night and day! Overall this feels like a quality product that punches above its weight in all regards, I was so impressed I immediately bought another one for a family member who appreciates good audio. I don't think you can go wrong at this price point.

As a daily driver of the Fosi Q4 DAC (in combination with the BT30D amp) for my computer, and a BT20D for the bedroom it's safe to say I like Fosi gear. The K5 Pro is a fantastic upgrade and replacement for the Q4 in several aspects. 1. Build quality and design: the new design of Fosi products has made the old black boxes look more sleek and modern. The gunmetal grey is stylish and works with any mini hifi setup or room. It just so happens to match the metal in my headphones and stand. 2. Connectivity: the Q4 used a 5v micro usb for power, then a full-size usb type B to connect to a pc (the optical and coaxial are the same on both models). With the K5, one usb c is used for both power and signal. What impressed me is the lack of interference when using the same cable for both. Initially I was skeptical of this (without cutting the cable to see) but I can assume that there is a good degree of shielding of the individual cores to prevent any interference or cross talk. In addition the K5 Pro has added a 3.5mm microphone input next to the 3.5mm headphone output. This output can power headphones from 16 ohm to 300 ohm. This is a 100ohm improvement over the Q4 and as I have a pair of HD660s it makes a lot of difference. Just like the Q4 there is a RCA output to connect to speakers or a seperate amp unit. 3. The DAC chip: the K5 Pro uses the new Texas Instruments NE5532 op-amp chip. Especially noticeable through headphones there is precise and punchy bass control and incredibly clear highs while never muddling the mids. 4. Gaming: both the K5 and Q4 are advertised as gaming DACs. The K5 really improves over the Q4 because of the NE5532 chip. Using Dolby Atmos for headphones the positioning and soundstage was perfect for FPS gaming and immersion. I have only one gripe about the K5 Pro. It's the power button. To turn on and off you have to long press the volume knob. This means every time the K5 loses power you have to turn it back on manually. The Q4 had a point on the volume where as you turn the volume up the DAC turns on. Once left at a volume the Q4 just turns on and off without having to touch it. It is all down to my laziness but the quick press of the volume to change the input is a very nice to have. In summary the K5 is a clear upgrade over my Q4. Comparing my review to others they are saying similar things. If you just want something that sounds great and incredibly portable to power your headphones or to connect to your active speakers the K5 is a no brainer for the price. If you want the best of both worlds by using a pair of headphones and passive speakers like me the price is a steal and leaves plenty of budget for an amp.

Good DAC that adds noticeable sound quality to high impedance headphones. A definite improvement over the motherboard sound card. easy to install, it is literally plug and play and gives good on the fly adjustment to volume & bass. This sits on my desk so is conveniently placed and it is powered by the PC so no external power is needed. Sound clarity is great and there is very little in the way of white noise when using at high volumes. I have found that now I have switched to In Ear Monitors, I don't need the benefits this DAC gives, but this is due to the low impedance of that style of headphone and not the K5. with IEMS I can't get anywhere close to max volume without a substantial amount of blood loss! If you are a true audiophile the K5 may be lacking in features but it is perfect for its advertised use case of gaming and I can absolutely hear the change in audio quality and clarity. directional sound is excellent and really adds to the gaming experience. A bonus was that it shipped with a headphone/microphone splitter cable for those using combined single cables.

I used to have Turtle Beach headphones when they came with the inline amps.. Sounds was always great, bass was powerful too. Since then, headphones I've had just didn't feel like they were powerful enough. After some (slightly confusing) searching for an "amp" this one looked to be perfect for what I needed. 3.5mm connector with USB C to USB A adapter which came with it. Plugged it into my pc, works brilliantly just like that. No custom software needed. I love turning bass all the way to max with treble at medium. But even with both the highest, the sound quality is superb. Having the control of Bass and Treble as well as volume ofc allows you to quickly and easily tune to your needs. One downside I've had is sometimes if the usb connector is nudged the wrong way while plugged in, it'll output non-stop loud static noise until I turn it off and back on again.

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

I bought this product after viewing some YouTube videos saying that it is a great product. Curiosity got the better of me and I decided to order it. I liked the idea of a better volume control and the addition of bass and treble controls. I also wanted to see if this DAC was better than the DAC in my Sony CDP-XA20ES. It is! I opened the box and unpacked it and immediately noticed that the build quality felt very solid and the controls felt firm and precise. The volume control is a neat multifunction control for volume, power on/off and input selection. I connected it in literally about a minute. I started playing CDs by using the Sony player as a CD transport and using the optical digital output to feed the optical input on the Fosi. I am using Sony MDR-7506 wired studio monitor headphones. The quality of the sound was instantly better than the headphone output on the front of the Sony. I so enjoyed the better quality that I was testing many different CDs to hear the difference. This product is so worth the money [to me anyway]. I can only say if you are thinking about it do it as I cannot imagine you not being happy with this product. Great addition. Six stars please.

Purchased this audio DAC because i was excited to see that FOSI AUDIO had just come out with a DAC that included headphone microphone input. I was an early adopter of this product and actually paid a premium price through amazon USA, shipped to Canada. I knew the similar FOSI Q4 had an excellent reputation for sound quality but unfortunately did not suit me because of the lack of microphone input. In come the FOSI AUDIO K5 MINI PRO.. I had to give this DAC a try. As soon as you handle this product you know you are getting a quality piece of equipment. Setup is easy, all you do is plug it into your computers USB port. No driver install, just tell your computer to play the audio from the device in your sound setup. Even comes with a dongle to allow for a combined audio/mic headphone set to plug into the separate jacks on the device. Audio quality - 10/10 excellent and an absolute steal for the asking price that I am now seeing on amazon as of DEC 29/2022 Microphone quality - 10/10 If you online game your friends are going to think you have a very fancy microphone with this DACs ability to amplify the microphone input. It can be almost too clear and loud on some headsets but this can be adjusted in the windows input microphone level settings and turned down. I did need to get support from FOSI and they immediately and quickly helped me with my advanced technical question and had my device working well with all my equipment. (I use quite a few different headphones w/mics and had an issue with one of them which FOSI solved) This K5 MINI PRO is on par with some of the very expensive DACS out there. There is only two features I wish that FOSI would add. Some sort of "go to sleep mode" and "auto wakeup on sensing sound" to have this unit automatically turn off after say 30min of inactivity and wake itself when needed. The other would be a volume adjuster for the microphone input. These are just wishes to make an already excellent product even better. You will not be disappointed with this product.

Gaming console when I purchase an Xbox series X and a PlayStation 5 Pro, I felt that when I attached or connected to my monitor which I use it mostly for my PC. Sound editing and image editing works. When I try to connect for the first time I saw that there was no sound coming so I got a HDMI extractor and I got this product and the functionality. The compactness the quality, the connectivity, the compatibility and mainly the sound quality of of each dynamic response is so good while playing games. You can adjust your required or desired tones through this and it has a very good amp and this is must for a gamer who is using with especially using monitor rather than a TV
