While many sellers list the specs, understanding them helps identify why the DAC performs the way it does.
To force the CX31993 to accurately read your headphones' impedance and deliver the correct voltage: Disconnect the CX31993 dongle from your phone or PC.
has established itself as one of the most popular budget USB-C Digital-to-Analog Converters (DACs) on the market. Offering an incredible price-to-performance ratio, it provides a massive audio upgrade for smartphones, laptops, and tablets that lack a native 3.5mm headphone jack. However, because many manufacturers build ultra-cheap dongles around this chip, users frequently encounter minor engineering bugs, driver conflicts, or unwanted noise.
Try connecting to a powered USB hub or directly to a laptop, rather than a phone, to ensure full power delivery. Use EQ software (like EqualizerAPO) to lift the sub-bass, as the is inherently neutral/bright. 3. How to Get "Better" Sound (Optimizing the CX31993) To truly make the cx31993 datasheet fix better
If you own an early PinePhone (Batch 1.0 or 1.1), there was a hardware design flaw regarding the microphone impedance matching with the Cx31993.
Use a TCXO (SiT1552) if you need low phase noise for 384kHz playback.
