Sony Headphones No Sound — Causes & Fixes

What Does This Error Mean?

Sony headphones with no sound are usually a volume or audio output routing issue on the device, not a headphone fault. Check phone volume, Bluetooth audio output, and app permissions.

How to Fix It

Check the volume on both the headphones and the device
Confirm audio is routing to the headphones
Check the audio source app
Disconnect and reconnect Bluetooth
Check the 3.5 mm jack
Factory reset the headphones

Frequently Asked Questions

Why do my Sony headphones have sound in only one ear?

Single-ear audio is usually caused by a dirty or damaged audio jack, a mono-mode setting on the source device, or a failed driver in one ear cup. Test in cable mode and Bluetooth to narrow down the cause.

My Sony WF earbuds have no sound even though they are connected — why?

WF earbuds sometimes lose sync between left and right. Place both in the case for 10 seconds, remove and re-pair. This re-syncs the two earbuds.

Can a firmware update fix Sony headphone audio issues?

Yes — Sony periodically releases firmware updates that fix audio bugs and Bluetooth compatibility issues. Update via the Sony Headphones Connect app.
