AI Verdict
A 0.176-ounce USB-C to 3.5mm adapter with CX31993 and MAX97220 DAC chips, designed for users needing 32bit/384KHz audio on USB-C devices.
This adapter is a situational fit for audiophiles and users with specific wired headphone needs, offering dual DAC chips (CX31993, MAX97220) and 32bit/384KHz audio output. Its plug-and-play nature and universal USB-C compatibility make it convenient for enhancing audio quality on various devices. However, the potential for heat generation and unspecified microphone support narrow its appeal.
If microphone support is crucial, look for dongle DACs that explicitly state 'microphone pass-through' or 'inline mic support' in their specifications.

What Buyers Say
Since the 'Date First Available' is in the future (May 25, 2025), there are no actual user reviews for this specific LKKLUYIC CT6 Pro adapter. However, based on general feedback for dongle DACs utilizing the CX31993 and MAX97220 chips, users typically report a noticeable improvement in audio clarity and power, especially for more demanding headphones. The plug-and-play aspect is usually appreciated, but some similar devices can run warm during use, and microphone support is often absent.
“Man, I just needed something to make my old headphones sound less flat on my new phone, and this little thing with the CX31993 chip actually makes a difference, but it does get a bit toasty after a while.”
Common Praise
- Expected to provide clear, high-resolution audio with good detail across the frequency range.
- Likely to offer sufficient power output for a variety of wired headphones, including higher impedance models.
- The compact, lightweight design and braided cable are generally seen as positives for portability and durability.
- The simple plug-and-play operation is a convenient feature for immediate audio enhancement.
Common Complaints
- Similar DAC dongles using these chips can get warm to the touch during extended listening sessions.
- Lack of explicit microphone support means it might not work for calls or gaming chat.
- Potential durability concerns if the DAC components are directly integrated into the 3.5mm jack, making the cable a critical digital link.
Ownership Tips
- Expect the small aluminum casing to feel warm, especially when driving power-hungry headphones.
- Without specific mic support, you'll probably need a separate solution for voice input.
- The braided cable, while looking sturdy, might be the weakest link if the internal digital wiring is prone to damage near the 3.5mm connector.
Frequently Asked Questions
Does this adapter require any special drivers or software?
No, it's designed for plug-and-play operation, meaning you can simply connect it to your USB-C device and start listening without installing anything.
Is this compatible with my iPhone 15/16 or Samsung Galaxy S23/S24?
Yes, it offers universal compatibility with iPhone series, S series, and other USB-C Android devices.
Can this adapter improve the sound quality of my existing headphones?
Yes, with its dual CX31993 and MAX97220 DAC chips, it's designed to deliver crystal-clear, high-resolution 32bit/384KHz audio, which can significantly enhance the sound quality of wired headphones, especially those with higher impedance.
Does this dongle support headphones with an inline microphone?
The product specifications do not explicitly mention microphone support. Many audiophile-grade dongles do not support inline microphones, so it's best to assume it might not work for calls or voice commands.
Will this adapter drain my phone's battery quickly?
While not specified for this exact model, DAC dongles generally draw power from the connected device. High-performance DACs and AMPs, especially when driving demanding headphones, can contribute to increased battery consumption.
Buying Guide
When you're looking at a USB-C to 3.5mm DAC adapter, you're basically trying to get better sound out of your phone or tablet for your wired headphones. The key is how well it converts the digital audio from your device into an analog signal your headphones can play, and if it has enough power to drive them. Don't just look for 'Hi-Res' – consider the actual DAC chips and amplifier, and whether it supports features you need like a microphone.
DAC Chip (CX31993) & AMP Chip (MAX97220)
These are the brains of the operation. The DAC (Digital-to-Analog Converter) takes the digital music file and turns it into sound waves. The AMP (Amplifier) then boosts that signal so your headphones get enough power to sound loud and clear. Better chips mean cleaner, more detailed sound, like upgrading from a basic car stereo to a premium one.
32bit/384KHz
This refers to the maximum audio resolution it can handle. Think of it like video resolution – 32bit/384KHz is ultra-high definition audio. While most people can't discern the difference beyond 16bit/44.1KHz (CD quality), it means the DAC is capable of processing very detailed sound, which can contribute to overall clarity.
Universal Compatibility (USB-C)
This just means it'll work with pretty much any modern phone, tablet, or laptop that has a USB-C port. It's like having a universal remote for your audio, so you don't need different adapters for different devices.
Alternatives
If this adapter doesn't fit your needs, search for dongle DACs with explicit microphone support, or those that feature a separate power input if you need to charge your phone while listening.
