POWERFUL. If you play FPS games and listen to music it will not let you down. I have it paired with the Sennheiser HD 660S2 which is a 300 ohm headset and it powers them effortlessly. I love the sound signature across the board.

As an IT guy who's fallen hard for budget-friendly hi-fi, the Fosi K7 blew me away. Plugged it into my desk setup (paired with Beyerdynamic DT880s and Sennheiser HD599s) and was shocked at how clean it sounded—way better than its price tag suggests. No fancy software, just plug-and-play via USB, optical, or Bluetooth. The bass/treble knobs are perfect for quick tweaks when switching from EDM (crisp, punchy lows!) to Elden Ring—spatial sound was surprisingly precise for gaming, too.My girlfriend nabbed it for her desk, and even she (total audio newbie) loved how easy it was to use. Build feels solid, nice weight, no sharp edges. Only gripes: the USB cable's a bit short for neat cable management, and I wish there were more EQ options for picky listeners. But for under $200? Insane value. For most headphones and casual setups, it's a home run. Fosi keeps hitting that sweet spot between "affordable" and "actually good". Highly recommend—just don't let your partner try it, or it'll disappear!

I bought it off the official fosi site with discount code for $160. It’s definitely worth it even at full price. Works well with PS5. If you are in need of an all in one Dac/amp this will be a hard one to beat at this price range. Sound quality is amazing and has good power to power most headphones.
