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.
Review: An overall great small amp to drive quality audio to most headphones with some QoL EQ knobs. - This little amp is the perfect addition to a nice pair of hifi headphones. I thought the 3 small metal knobs would be pretty gimmicky but I turned out to change my mind in practice. Sometimes I will be playing a game where theres just too much bass in the mix and I'm having trouble hearing footsteps, so I just turn the knob down halfway and voila, perfect mix again. Same for movies and tv shows but in reverse. I have a pair of Philips shp9500 and so if I am watching a tv show, I usually just crank up the bass just a little bit to give it that 'oomph' feeling. The amp overall can push up to 300 ohms and it gets way too loud for me, it would damage my ears if I turned it all the way up. The build feels great, its smaller than I thought and I actually like that. Its this little chunk of metal that just outputs great audio.

### ⭐⭐⭐⭐ 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
