USB C to 3.5mm Audio Adapter with Dual Chip CX31993 MAX97220 DAC & HiFi Amplifier (BZINK)
Quick take
This BZINK USB-C to 3.5mm adapter turns your device’s digital audio into an analog headphone signal using dual DAC chips (CX31993 and MAX97220). It is a good fit if you want a simple aux solution for Android, iPhone USB-C models, iPads, and computers, with support for high-resolution audio formats. The main buying caveat is device compatibility, including that it is not supported for some consoles, and Apple earbud volume control is limited.
Pros and cons
Pros
- Dual-DAC design (CX31993 + MAX97220) aimed at clear, low-distortion playback.
- High-resolution support up to 32-bit/384kHz DAC decoding and 24-bit/96kHz ADC transmission.
- Built for everyday use with a metal housing, slim cable design, and a mic-capable TRRS path for calls on compatible headphones.
- Broad device compatibility across many USB-C phones, tablets, and Macs (with a USB-A adapter included).
Cons
- Not compatible with PS4/PS5.
- Does not support volume control for Apple’s wired EarPods.
- Sound tuning can matter, some listeners describe a noticeable output character compared to other dongles.
What buyers think
Buyer-review evidence is generally positive for sound quality in this adapter’s size and category, with recurring themes of clean output and no audible distortion or noise during use. Several buyers also describe it as handy for keeping their wired IEMs in a USB-C lifestyle, and they mention it behaving well with on-ear monitors and IEMs. At the same time, review evidence is limited on deep, objective performance metrics, and a small number of comments suggest the tonal balance may not perfectly match every high-end or car audio setup, so tuning expectations should be realistic.
How it works and what it’s for
This is a USB-C (and USB-A via the included USB-A interface) to 3.5mm headphone adapter with an internal DAC/amp stage. In plain terms, it gives your aux headphones or IEMs a way to play audio from a device that does not have a headphone jack. It also supports microphone use for many 3.5mm headsets that use a TRRS plug, so it can cover calls and voice input, not just music.
Sound quality expectations (and what reviews suggest)
On paper, the adapter is built around a dual-chip approach, using CX31993 plus MAX97220 for the conversion and amplification stage. It is also described as having high-resolution decoding support (up to 32-bit/384kHz) and strong noise performance figures, which aligns with what many buyers report: clean, neutral-leaning, and distortion-free sound for everyday listening.
One important nuance is that dongle sound can vary by output level, headphone impedance, and your EQ preferences. Some buyer notes indicate a more “colored” or boosted character in certain use cases, especially if you are trying to integrate it into a very specific car audio setup or you want perfectly neutral tuning without adjustment.
Key specs that matter for buying
- Connector: USB-C to 3.5mm (with USB-A interface included for wider compatibility).
- DAC and ADC: DAC up to 32-bit/384kHz, ADC up to 24-bit/96kHz.
- Performance claims: signal-to-noise ratio listed as 124dB at 32 ohms, and THD+N listed as -95dB at 32 ohms.
- Cable and build: described as an 8-strand 4N single-crystal copper silver-plated cable, plus an aviation-grade aluminum alloy housing intended to resist scratches and rust.
Compatibility notes you should check first
This adapter is designed for a wide range of USB-C devices, including smartphones and tablets from major brands, and it also lists support for some iPhone USB-C models. There is also a note that it provides microphone functionality for most 3.5mm headphones with a TRRS plug.
Before buying, double-check three things:
- Gaming consoles: it is not supported for PS4 or PS5.
- Apple wired EarPods controls: volume control for Apple EarPods is not supported.
- Your headphone plug: mic support depends on using a compatible TRRS 3.5mm headset design.
Pros and cons for different headphone setups
Best for
- USB-C phone or tablet users who want a reliable aux connection for wired IEMs and on-ear monitors.
- People who care about clean, low-noise playback and want a straightforward DAC/amp without complicated setup.
- TRRS headset owners who want microphone support for calls or voice input.
Who should avoid it
- PS4/PS5 owners looking for headphone output, since this adapter is not compatible.
- Apple EarPods users who specifically need inline volume control functionality.
- Buyers using it in highly tuned audio environments (for example, very specific car integrations) where even small changes in output character could require EQ or may feel “too boosted” for the setup.
Verdict
The BZINK CX31993 + MAX97220 USB-C to 3.5mm adapter is a strong option for shoppers who want a compact aux dongle with clean sound performance and high-resolution support for everyday listening. If you are buying mainly for music, calls with a TRRS headset, and broad USB-C device compatibility, it fits the use case well. Just confirm it matches your headphone plug type and that you are not relying on PS4/PS5 or Apple EarPods volume control.
