What Buyers Say
Users generally find DACs with the CX31993 and MAX97220 chips to provide a clean and detailed audio experience, often noting a lack of noticeable distortion. The plug-and-play nature across various operating systems and gaming consoles is a recurring positive, making it convenient for diverse setups. However, some similar dongles have shown minor noise with extremely sensitive IEMs, and the absence of a stated power output for this specific model leaves questions about driving high-impedance headphones. Physical fragility has also been a concern for some users of comparable products.
“Okay, so I plugged this thing in, and my music actually sounds like, *alive* now, not just flat. But sometimes it's a little finicky connecting to my phone, gotta wiggle it. Still, totally worth it for the sound.”
Common Praise
- Audio output is clean and transparent, without noticeable distortion or noise floor.
- Plug-and-play functionality works across Android, Windows, Mac, and gaming consoles like Switch and PS5.

- Provides a noticeable upgrade in sound clarity and detail compared to device's built-in audio.
Common Complaints
- Some users of similar dongles experienced intermittent connectivity issues, requiring the device to be unplugged and re-inserted.

Buying Guide
When you're looking at a USB-C DAC dongle, you're essentially buying an external sound card for your phone or computer. It takes the digital audio signal, converts it to analog, and amplifies it for your headphones. This process bypasses your device's potentially lower-quality internal audio components, giving you cleaner, more detailed sound. The key is how well it does that conversion and how much power it can deliver to your headphones.

Alternatives
If this DAC doesn't provide enough power for your specific headphones, look for alternatives that explicitly list higher output power (e.g., 100mW or more at 32Ω). If you need balanced audio output (e.g., 4.4mm jack), you'll need a different dongle, as this one only has a 3.5mm output.
