Quick Answer:
If your USB-C earphones aren't working, first check that the earphones work on another device. Then clean the USB-C port gently with a soft brush to remove dust or debris.

Section 1 – Earphones Not Detected

If your phone doesn't recognise your USB-C earphones at all, the issue is usually port debris, compatibility, or hardware.

Try these in order:

  1. Check the earphones on another device – This tells you if the problem is the earphones or your phone.
  2. Clean the USB-C port – Power off your phone. Use a soft, dry brush (like a clean toothbrush) to gently remove dust or debris from the port. Avoid using liquids or metal objects. This is one possible cause, but not the only one.
  3. Restart your phone – A full reboot can resolve temporary software issues that affect USB audio initialisation.
  4. Check compatibility – There are two types of USB-C earphones:
    • Digital (with built-in DAC) – Most common. Work on most modern Xiaomi devices.
    • Analog (via USB-C analog mode) – Rare. Some older Xiaomi devices may not support analog USB-C audio.
    If you're using an adapter, try a different brand or an official Xiaomi adapter if possible.
  5. Test with a different USB-C earphone or adapter – If another earphone works, the issue is your earphones. If not, the issue is your phone.

Section 2 – Earphones Detected but No Sound

If your phone shows a headphone icon but no sound comes out, the issue is likely audio routing or an app conflict.

Try these in order:

  1. Check volume settings – Ensure the volume is turned up and the phone is not muted.
  2. Check the audio output device – When you plug in earphones, you may see a USB audio notification on some apps or devices. If available, tap it to ensure the phone is routing audio to the USB device.
  3. Check USB audio routing in Developer Options (if available) – Enable Developer Options (Settings → About phone → tap MIUI/HyperOS version 7 times). Go to Settings → Additional settings → Developer options → look for "Disable USB audio routing" – ensure this is turned OFF. This option is only available on some Xiaomi devices.
  4. Restart your phone – A reboot can reset audio routing.
  5. Test with a different app – If the issue is only in one app (e.g., WhatsApp), the app may be the problem. Try the earphones with the built-in music player or a different app.

Section 3 – Earphones Stopped Working After a System Update

If your USB-C earphones worked before a MIUI or HyperOS update but stopped after, the update may have changed settings or introduced a bug.

Try these in order:

  1. Restart your phone – A second reboot after the update can sometimes resolve issues.
  2. Check USB audio routing in Developer Options (if available) – Section 2.
  3. Check for another update – Sometimes a follow-up patch fixes issues introduced by the previous update.
  4. Factory reset (only if all else fails) – If nothing else works and the earphones still work on other devices, back up your data and perform a factory reset. This is rarely necessary for USB-C audio issues.

Why Don't USB-C Earphones Work on Xiaomi?

  • Port debris – Dust or lint in the USB-C port can prevent a proper connection.
  • Compatibility issue – There are two types of USB-C earphones: Digital (with built-in DAC) and Analog (via USB-C analog mode). Some older Xiaomi devices may not support analog USB-C audio.
  • USB audio routing – The phone may be routing audio to the wrong output.
  • App conflict – A third-party app may be interfering with audio output.
  • Software bug – After an update, settings may be reset or a bug introduced.
  • Hardware fault – The earphones or the phone's USB-C port may be faulty.

⚠️ What NOT to Do

  • Don't use liquids or sharp objects to clean the USB-C port – This can damage the port. Use a soft, dry brush or compressed air.
  • Don't force the earphones into the port – If it doesn't fit easily, check for debris or use a different earphone.
  • Don't factory reset without backing up first – You'll lose your data.

Quick Questions

Why are my USB-C earphones not detected on Xiaomi?
Most commonly, the USB-C port has dust or debris, or there is a compatibility issue. Clean the port gently with a soft brush and test the earphones on another device.

Why do my USB-C earphones work on other phones but not mine?
The issue is your phone – usually port debris, a software setting, or compatibility. Try the steps in Section 1.

Do all Xiaomi phones support USB-C earphones?
Most modern Xiaomi, Redmi and POCO devices support USB-C audio. Compatibility varies depending on whether the earphones use a built-in DAC (digital USB-C audio) or analog mode. Some older devices may not support analog USB-C audio.

Can a system update cause USB-C earphones to stop working?
Yes. Updates can change settings or introduce bugs. Try restarting and checking USB audio routing in Developer Options (if available).

How do I enable USB audio routing on Xiaomi?
If available on your device, go to Settings → Additional settings → Developer options → ensure "Disable USB audio routing" is turned OFF.

Xiaomi Equalizer Settings: Best Sound for Headphones & Earbuds (UK 2026)

How to Boost Headphone Bass on Xiaomi Phones (MIUI Guide for UK Users) Music is closely tied to emotions, and for many UK users, headphones are a constant companion throughout the day—whether commuting in London , relaxing in a Manchester flat, or catching up on podcasts in Birmingham . Naturally, everyone wants the best possible sound quality from their Xiaomi device, without relying on third-party apps that take up storage space. Why Bass Matters Before boosting headphone bass, it’s worth understanding the basics. Humans can hear frequencies from 20Hz to 20kHz. The lower end, below 250Hz, represents bass sounds. Within this range, the lowest frequencies contribute to deep bass, while slightly higher frequencies provide “punchy” bass. MIUI’s equaliser allows you to tweak these frequencies, regardless of the headphone model—be it Mi AirDots , Redmi AirDots S, or higher-end wired headphones. Setting up the equaliser properly is crucial for achieving the richest sound experience...
