## Description

desertcart.com: Fosi Audio 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 : Electronics

Review: One of the BEST DAC/amp to have - 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.
Review: An excellent budget external DAC, but you need to know what you're getting - 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

### ⭐⭐⭐⭐ Very good for the price
*by L***E on January 12, 2026*

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
