Comparison K5 Pro Q4 SK01 SK02 PH04 PH05 P3 Review: Game Changer for Console Audio - 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. Review: The best thing I ever bought that I didn't know I needed. - 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. ## 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.

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 ## 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.vn/products/486694356-fosi-audio-k5-pro-gaming-dac-headphone-amplifier-mini-hi](https://www.desertcart.vn/products/486694356-fosi-audio-k5-pro-gaming-dac-headphone-amplifier-mini-hi) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
