What accessories are included with the DS3?

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.

How do I switch gaming sound effects on the DS3?

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.

Can I change digital filters on the DS3?

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.

How do I change UAC modes on the DS3?

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.

How do I toggle high/low gain on the DS3?

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.
