One of the iPhone users compared her ear pods with one of her sisters, and ones are much louder.
I google it and found some solutions to resolve the issue
Method 1: How to rectify the low sound on your EarPods
- Check the volume setting on your iPhone, iPad, iPod or Mac.
- Make sure that the meshes in the earbud holes are free of lint or other debris.
- If any of the meshes in the earbud look clogged, use a clean, small, dry, soft-brushed brush to clean them. Gently brush all the openings.

Method 2: Clean your ear pods with toothbrush
One of the users uses ear pods a lot at night in bed. This results in a warming of the wax in the ears and effective muting sound comes. To solve this issue, warm up the wax film, and then remove them from your ears and brush the main grille repeatedly with firm but gentle pressure using a toothbrush.
