Review: Great but needs the equalizer - Having the ds1 and enjoying it with music, decided to try this ds3 in gaming mode. I got the black and its def lighter in weight probably because the back is tempered glass now. It does look good but is a fingerprint magnet. People say its hard to operate but its fairly easy. It has a 60 step volume. This has a fairly low 1.2mw or 2.2mw output based on which cable tyoe you use. Balanced cable should give you the 2.2mw output but didnt seem nearly double the volume. Maybe 1/3 louder. But tweaking volume on either pc or iphone and on dac dongle you can get it to pretty high volumes. I’m using senheiser hd620s headphones. Its easy to upgrade firmware from their dl area and they have a windows driver although not sure if you really need it as the manual says drivers arent needed for windows. Unfortunately i did not find the web based equalizer that seems like it came with older versions of the firmware. But without it heres how to operate it easily. Just plugging it in will show red led (music mode), i leave it in default filter mode 1. But holding volume + and - down you will see a light blueish flash, you are now in mode filter two. Do it again, it will flash again, now filter 3. You can do it all the way to filter 8 which you will see two flashes. To get back to filter 1 hold down the buttons again it will flash once and back to filter 1. If you forgot, just unplug from your source and it should reset to filter 1. Game mode, say on your pc, before plugging dongle in your usb c port, just hold down the + volume button and then plug in. Keep holding it till you see led turns a yellow green color and let go. This is standard game mode. Holding down - and + till light changes to bluish color for fos mode. Holding it down again toll it changes purple is 7.1 surround mode. All of above is normal gain mode. If you accidentally pressed volume - & + momentary in either music or gaming modes, it changes gain to a higher gain mode and i didn't need this or use it as normal gain was loud enough. Also whatever mode youre in, with high gain on, the led light now flashes that color be it red for music, it will now flashes red. Same with gaming, if fps mode blue, in higher gain mode it will flash blue. Now to how it sounds. Music as i said i only used the default and it was perfectly fine. Gaming normal mode was ok, seemed like it was similar to standard music mode. Fps mode i think i did hear sounds more relevant to where the sound source was like voices to the side, things moving left or right things like that. So its ok but its subtle. 7.1 mode is not echoey like some people say. It does have a more 3d like sound and enhances directional sounds but it def wasnt echoey. Explosions do get louder as it tries to simulate sound from a simulated 7.1 speaker setup. I think it makes games a little funner with the more dynamic sounds. Anyways great, but would be better if they can get the equalizer on their dl site.
Review: Easy to use and creates a more detailed sound. - Works great and sounds fantastic paired with Sennheiser HD560S headphones. Amazing detail.

## Questions & Answers

**Q: What accessories are included with the DS3?**
A: The box contains the DS3 dongle DAC/amp, a USB-C cable, a USB-C to USB-A adapter, a quick-start guide, and the user manual—everything you need for plug-and-play listening on phones, PCs, PS5 or Switch.

**Q: How do I switch gaming sound effects on the DS3?**
A: In UAC 1.0 gaming mode, long-press both Volume+ and Volume- buttons to cycle through No Effect(yellow) / FPS Effect(blue) / 7.1 Spatial Audio Effect(purple); 7.1 creates a 360° immersive soundstage-no drivers needed.

**Q: Can I change digital filters on the DS3?**
A: Yes—long-press both volume keys in UAC 2.0. Filters 1–7 blink once, Filter 8 blinks twice; pick the curve that best suits your headphones and music.

**Q: How do I change UAC modes on the DS3?**
A: Plug in to default UAC 2.0 (red LED). Hold any volume key while reconnecting for UAC 1.0 (yellow). Swap back by unplugging and re-plugging the USB-C cable.

**Q: How do I toggle high/low gain on the DS3?**
A: Short-press both volume keys together. In UAC 2.0, red flash = high gain, solid red = low. In UAC 1.0, watch the last color: flash = high, steady = low—yellow for no effect, blue for FPS, purple for 7.1.

### ⭐ Dull and lifeless
*by H***. on May 7, 2026*

This thing... Wow. Where do I start? I purchased some highly rated Sennheiser headphones along with this one, in expectations that I would hear something incredible, but I found the opposite. It removes all life from all music and makes it dull and lifeless. After weeks of testing, my desktop speakers also confirm this. I would give it zero stars, but that's not an option. What is FOSI attempting with this? They are hyping it. Now it is sitting in my drawer, waiting for another day of testing... In which I know it will fail... Update: After a couple of months, I finally found something that works a little bit with this thing: some crappy Sony earbuds. My expensive AKG earbuds don't work with them as well. Even then, the Sony don't present anything remarkable. Just barely above average. Still one star for the FOSI DS3.
