Welcome to Apple Support Communities.
If I'm understanding correctly, after several pairs of earbuds you are still having issues as they begin to fail after a while. I know how important it is to have working equipment and will be happy to assist.
Please try the steps in the following article: If your headphones don‘t work with your iPhone, iPad, or iPod touch
Check for debris, damage, or loose connections
- Check for debris in the headphone port on your iPhone, iPad or iPod touch.
- Check your headphone cable, connector, remote, and earbuds for damage, like wear or breakage.
- Look for debris on the meshes in each earbud. To remove debris, gently brush all openings with a small, soft-bristled brush that's clean and dry.
- Firmly plug your headphones back in. If your iOS device has a case, remove the case to get a firm connection.
If your headphones still aren't working, follow the steps below for your issue.
If you can't hear any sound or if only one side of your headphones works
- Adjust the volume with the volume buttons on your iOS device or use the Volume slider in Control Center.
- To see if you need a replacement, try a second pair of headphones. If the second pair works, contact the manufacturer of the initial pair and ask if you need a replacement. If the second pair doesn't work, contact Apple Support.
Cheers.
