The mix of USB-C, optical, 3.5mm, and 4.4mm balanced outputs looked practical for everyday use without taking up much space.Going in, I expected a clean-sounding DAC/amp that could push regular headphones and some planars without noise or strain, plus basic preamp use. It mostly delivered. The aluminum case feels solid and sits steady on the desk. The big volume knob is smooth, and the gain switch plus LEDs make it easy to see what’s going on. Plug in via USB-C or optical and it just works—no drivers needed on my end.Sound is neutral and clear. Bass stays tight, mids are open, and it has enough power on the balanced 4.4mm side to give harder-to-drive headphones some headroom. I use it for music and gaming, and the quieter background helps pick out details better than the motherboard jack. The line out also works fine if I want to feed a powered speaker or another amp.For daily desk use it’s handy—connect the PC or a TV via optical, switch headphones quickly, and keep the volume independent. Value feels solid for what you get in power and inputs at this price point.A few things keep it from being perfect. The treble can come across a bit linear or bright depending on the headphones. It always needs USB-C power, so it’s not fully portable. And there’s no app or fancy tuning options if you like tweaking on the fly.It met my main expectations for cleaner desktop audio and enough power without complications. Not the last word in refinement, but a practical step up from basic PC sound that does the job well. ### ⭐⭐⭐⭐⭐ Fosi DAC *by on Reviewed in the United States August 25, 2026* Works great !! I connected it to my laptop via a USBc cable. I noticed an improvement in overall sound. I’m running it through a Fosi BT30D Pro. Makes for a cool, compact, and clean sounding desktop set up. I used Google to help with optimizing the processing settings. Would definitely buy again…. Well I would…. If I had another home office computer. ### ⭐⭐⭐⭐⭐ Excellent But Lacking One Important Feature For Me *by on Reviewed in the United States January 10, 2026* Although I returned this Fosi Audio SK02 DAC Amp Headphone Amplifier I am giving it 5 stars because for what it is and for it's price I think it's a good value and performed well for me while I was trying it out. One of the reasons I considered this product was because of the high headphone power output and inclusion of both single ended and balanced headphone outputs. The power was definitely sufficient to drive all the headphones I own (Sennheiser HD6XX, Sennheiser 560S, HiFiMan Edition XS, FiiO FT1, Grell OAE1) although I didn't try it with some vintage 600 Ohm headphones I own. However, I returned it because I really needed to be able to see the volume level that was set more clearly than what the small led light could indicate. That single light was too vague to know where in the scale the volume was set. I have opted to choose another product that has an led screen which can constant show the volume from 0 to 99 at all times. This may not be a consideration for other people however. I also liked the form factor and design which took up less space on my desktop than the other product I ended up selecting. So, in summary, I consider this a very good product that unfortunately just didn't meet my specific needs. If the lack of constant volume level indicator and led screen isn't an issue, then you would probably be happy with this DAC/Headphone Amp. ## Frequently Bought Together - Fosi Audio SK02 DAC Amp Headphone Amplifier Desktop USB C to AUX Digital to Analog Audio Converter Adapter Preamp Optical to 3.5mm 4.4mm Balanced Combo for Home Audio System - Fosi Audio SK01 Headphone Amplifier Equalizer Preamp with Bass Midrange Treble Tone Control and Loudness Compensation Portable Class A Analog Amp for Electric Guitar Instrument with 3.5mm 6.35mm Jacks --- ## 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.sn/products/611044029-fosi-audio-sk02-dac-headphone-amplifier-for-pc-desktop-balanced](https://www.desertcart.sn/products/611044029-fosi-audio-sk02-dac-headphone-amplifier-for-pc-desktop-balanced) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-10-22*
