Build Quality

The Xiaomi adapter is surprisingly well-built for ¥29. The braided cable is flexible and the USB-C and 3.5mm connectors have aluminum housings with Xiaomi’s matte gray finish. The DAC chip supports 96kHz/24-bit output — higher than the Apple adapter’s 48kHz/24-bit.

“For ¥29, the audio quality is genuinely good. The Realtek DAC produces cleaner output than my phone’s built-in headphone jack with less background noise. It drives my Moondrop Chu II (16Ω) easily with plenty of headroom. But try it with 64Ω studio headphones and it runs out of power quickly.” — SMZDM user

Purchase Recommendations

✅ Worth Buying (¥29)

If you have a phone without a headphone jack and listen to music through wired earphones, this is the best budget option.

💰 Premium Pick (¥149 / JCALLY JM6)

For high-impedance headphones (over 32Ω) or audiophile use, the JCALLY JM6 at ¥149 offers a more powerful DAC/amp with 2V RMS output.

⚠️ Warning

Check phone compatibility before buying. Some OnePlus and Samsung models have USB-C port configurations that don’t pass audio through this adapter.

FAQ

Q: Can I use this with a mechanical keyboard’s 3.5mm headphone jack? A: No, this adapter is designed for mobile devices and PCs. The output power is too low for keyboard audio pass-through.
