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 Review: Hell yeah brother - Simple, cheap, solid build, will make your headphones sound WAY better. Just buy it. I didn't know what what i was missing lol ## Features - The upgraded version of Fosi Audio Q4 adds microphone function, K5 Pro headphone DAC amp combo, next-generation audio converter with unrivaled internals, more outstanding performance, and richer audio details.

Just buy it. I didn't know what what i was missing lol ### ⭐⭐⭐⭐⭐ Game Changer for Console Audio *by T***N on March 31, 2026* With the release of Marathon, I wanted something that would help provide a boost in audio clarity over what the PlayStation's DualSense controller was putting out. Enter the Fosi Audio K5 DAC. This unit plugs directly into the PS5 via USB-A (Console) to USB-C (DAC). The PS5 immediately recognized the device as a supported audio output device, and can easily be enabled in the quick settings menu. For the unit itself, it is solidly built and has a decent heft. An all aluminum body with solid rubber feet. Separate connections for headphones and microphone input via included splitter cable. This cable is of questionable quality and found that it would need to be reseated as I would occasionally lose microphone input. Might be a shielding issue. Separate bass, treble, and volume toggles which provide an ample boost from the flat output curve of the DualSense. Higher quality audio with a wider soundstage and more precise imaging, which for multiplayer competitive FPS, is absolutely desired and highly appreciated. Overall, pleased with my purchase and would recommend to anyone seeking to get more of a fuller audio experience from their PS5. ## Frequently Bought Together - 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 - beyerdynamic DT 990 Pro 250 ohm Over-Ear Studio Headphones For Mixing, Mastering, and Editing --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/486694356-fosi-audio-k5-pro-gaming-dac-headphone-amp-hifi-headphone](https://www.desertcart.gr/products/486694356-fosi-audio-k5-pro-gaming-dac-headphone-amp-hifi-headphone) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-24*
