Applicable Products and Categories of This Article

Follow these steps to troubleshoot the issue:

Before you start

Radio interference will affect the Bluetooth® communication between the headphones and the playback device. The interference is likely to occur in a crowded place, near a store's cash registers, near a microwave, near traffic lights or automatic doors, inside a crowded train or in a station, etc. To avoid interference, move the headphones and speaker closer or set the sound quality mode to Prioritize Stable Connection in the Sony | Sound Connect app.

Solution

Select the situation when noise is heard:
Noise is heard when the headphones are exposed to wind

To reduce the wind noise, turn Off the Noise Canceling or Ambient Sound Control. Go to step 4.
Noise is heard while walking or running

When the Noise Canceling or Ambient Sound Control is On, the vibration of walking or running may be transmitted from your body and cause noise. To avoid this, turn Off the Noise Canceling or Ambient Sound Control. Go to step 4.
A rustling noise is heard when I move my body or head

The headphones' microphone and your ear may be in contact with each other. Check the way the headphones are worn. Go to step 3.
White noise (a small electrical noise with continuous static sound) is heard
- When the Noise Canceling function is ON
  To avoid white noise, turn off the Noise Canceling function.
  Note: If the white noise is heard during a phone call, refer to The noise canceling function does not work or white noise is heard during a call on the headphones article. Go to step 4.
- When the Ambient Sound Mode function is ON
  The noise may be heard depending on the value of the Ambient Sound Mode. Change the value on the Sony | Sound Connect app:
  1. In the My Device tab, select Device settings → Sound tab, and tap the down arrow on the right side of the Ambient Sound Control menu.
  2. Move the slide bar to adjust the Ambient Sound level.
Noise is heard when I push the headphones into my ears or when I tap the touch sensor strongly

This temporary noise can happen because of the headphones' Noise Canceling or Ambient Sound Control function and air-tightness. This is normal and not a malfunction.
An echo is heard when I cover the headphones or pinch around the built-in microphone with my hand

An echo in this situation is normal and not a malfunction.
Noise is heard when the surrounding ambient noise is loud, such as when I am in a station or near a construction site.

When the Ambient Sound Control is On, the surrounding noises can be easily heard. Turn on the Noise Canceling or the Ambient Sound Control function.
Noise is heard while talking on the phone

Go to step 2.
None of the conditions listed

If you hear your heartbeat or breathing, or if noise occurs when you change your posture, such as moving your neck, this is normal and not a malfunction.
For other noises, go to step 7.
If noise is heard during a phone call, select the appropriate situation:
The noise occurs when I talk
Go to step 3.
The noise occurs when the other person talks
Go to step 8.
Fit the headphones to your ears firmly.
If the earbuds are not worn properly, do not fit your ears, or the air-tightness is insufficient, the phone call quality may decrease. To maintain quality, consider these factors:
- Make sure that headphones are worn properly
- Select the earbuds that best fit your ears. Measure the air-tightness of the earbud tips and find the optimal size of earbud tips using the Sony | Headphones Connect app
- Make sure that the headphones' microphone and your ear are not in contact with each other.
For additional details, refer to the How to wear the headphones properly and select the most suitable earbud tips article.
