To pair your Sony WH-CH400 headphones, turn on the headphones and hold the power button until the indicator flashes blue and red. Then, enable Bluetooth on your device and select "WH-CH400" from the list of available devices.
Ensure that the USB charging cable is securely connected to both the headphones and a power source. If the headphones still do not charge, try using a different charging cable or power adapter.
To reset the headphones, press and hold the power button and the volume down button simultaneously for about 7 seconds until the indicator light flashes.
Poor sound quality can be due to interference or a weak Bluetooth connection. Try moving closer to your audio source or removing any obstructions. Ensure your headphones and the source device have sufficient battery life.
No, you cannot use the headphones while they are charging. Ensure the headphones are fully charged before use.
Use a soft, dry cloth to gently wipe the headphones. Avoid using any liquids or cleaning agents directly on the headphones.
Check if the headphones are charged. If not, connect them to a power source. If they still do not turn on, try resetting the headphones.
To maximize battery life, lower the volume, disable unnecessary features, and ensure the headphones are fully charged before extended use.
The Bluetooth range is approximately 10 meters (30 feet) in an open area. Obstacles such as walls and other electronic devices may reduce this range.
When you turn on the headphones, the indicator light will flash to indicate the battery level. You can also check the battery status on the connected device if it supports this feature.
