CX31993 HiFi USB DAC Type-C to 3.5mm headphone amplifier, digital audio decoder

About this deal

This compact dongle converts a USB-C port into a 3.5mm headphone output, making it ideal for smartphones, tablets and laptops that lack a traditional headphone jack. Built around the CX31993 chip, it is a highly integrated USB-C DAC and headphone amplifier supporting high-resolution audio playback up to 32-bit/384kHz PCM. Signal-to-noise ratio is quoted at over 128dB, and output power is rated at 65mW, with DSD 64/128 support also listed. The adapter supports UAC 1.0 for native plug-and-play use, meaning no drivers or apps are needed. It is primarily designed for devices with USB-C ports supporting USB Audio Class 1 or UAC2, and generally works well with modern Android devices, Windows PCs, macOS computers and some Linux distributions. Well-suited to IEM users and anyone wanting a straightforward step up from a phone's built-in audio output, the CX31993 presents a neutral-to-slightly-bright tonality with a very quiet background and open presentation.
