Why can’t I adjust the volume using gestures even after enabling the setting?

1. This product only supports volume adjustment via the roller. 2. Due to compatibility differences in Bluetooth protocol versions across operating systems, some phones or computers may not support the volume control protocol. This is a known limitation affecting many over-ear Bluetooth headphones on the market. If you encounter this issue, try connecting the headphones to another commonly used device and attempt volume adjustment. If volume control works as expected on the other device, the issue lies with the terminal device, not the headphones. You can continue using the headphones with confidence.
