Portable DAC Amp for USB-C devices

The Giabuao GiBA37 is a USB-C to 3.5mm audio adapter that integrates a CX31993 DAC and a MAX97220 headphone amplifier. It targets listeners who want higher fidelity than a standard phone jack can provide. The dongle works with iPhone 15, 16 and 17 models as well as Android phones, tablets, Macs and PCs. It is not for users whose devices lack a USB-C port or who require balanced output.

Plug-and-play with in-line controls

The adapter requires no driver installation on supported hosts and draws power directly from the USB-C bus. A TRRS 3.5mm socket enables microphone use and in-line remote functions for calls and music playback. Volume cannot be adjusted on Apple EarPods through this device. To avoid a popping sound when connecting headphones, set the source volume below 30 percent before plugging in.

Limited by USB audio class and output power

The CX31993 supports 32-bit 384kHz PCM playback, but the host must implement UAC 2.0 for those rates to be available; the Switch works only when it supports that class. The MAX97220 delivers 63mW into 32 ohms and is optimised for 16 to 32 ohm loads, so high-impedance planar or studio headphones will not reach adequate volume. The PS5 is not compatible.

Questions about this item

How can I confirm the CX31993 DAC is delivering 32-bit/384kHz output after connecting it?

The adapter uses the CX31993 DAC chip rated for 32-bit/384kHz and the MAX97220 amp with 124dB SNR and 95dB THD+N; you will hear a pitch-black background and clear instrument separation when playing Hi-Res files.

What comes in the box and is the USB-A interface included?

The package contains the USB-C to 3.5mm DAC amp dongle with a silver-plated cable and a USB-A interface for maximum versatility; no separate cable or accessory is required.

Which headphone impedance range works best with the 63mW@32 output?

The amplifier is optimised for 16-32 ohm loads and delivers 63mW@32 ohms, so it drives most in-ear monitors and portable over-ear headphones cleanly.
