Playback Volume Is Too Low

First check the volume on the earbuds and your phone or computer.

Reposition the earbuds so each sound outlet points toward the ear canal; an off-angle fit can make audio seem quieter.

On iPhone, no separate volume-sync setup is usually needed.

On a compatible Android phone, check whether Bluetooth volume synchronization is enabled; the location of this setting varies by phone.

Try another track or app, then another device, to see whether the issue follows the source.

Keep volume at a comfortable level.
