How to Fix High-Pitched Noise / Screeching sound in Sony WH-1000XM4 Headphones (Microphone & ANC Fixes)
Is your Sony WH-1000XM4 making an annoying high-pitched noise? This common issue is often linked to microphone interference, ANC glitches, or hardware faults. In this guide, we’ll explain the root causes and provide step-by-step fixes, including professional repair options if DIY methods fail.
Why Is My Sony WH-1000XM4 Making a High-Pitched Noise?
The pitch noise issue usually stems from:
Microphone Interference in ANC/Ambient Mode
The XM4 uses multiple mics for noise cancellation. If one fails, it can cause screeching or static.
Feedback Loops & Echo Effects
Internal audio looping can create continuous whining or buzzing.
Dust, Moisture, or Blocked Microphones
Debris in mic holes disrupts sound processing, leading to distortion.
Outdated Firmware or Software Bugs
Glitches in Sony’s ANC algorithms may trigger unwanted noise.
Hardware Failure (Defective Mic or Circuit)
If one earcup is affected, a faulty microphone or damaged wiring could be the culprit.
How to Fix Sony WH-1000XM4 Pitch Noise (DIY Solutions)
Update Firmware & Reset Headphones
- Open the Sony Headphones Connect app → Check for firmware updates
- Factory reset (hold Power + NC/Ambient button for 7 secs)
Clean the Microphone Ports
Use compressed air or a soft brush to remove dust from mic holes.
Disable ANC & Ambient Sound
Test if noise stops when ANC is off (press & hold the NC/Ambient button).
Disable DSEE Extreme & Voice Assistants
- Turn off DSEE Extreme (Sony app → Sound settings)
- Disable Google Assistant/Alexa to prevent mic conflicts
Test in Wired Mode
Connect via 3.5mm cable (ANC still works). If noise disappears, the issue is Bluetooth/mic-related.
