My iPhone 7 Plus is not recognizing my wired headphones

Hi sajina272,

Thanks for using Apple Support Communities. We understand your headphones aren't working with your iPhone. We're happy to help. Start with the steps to resolve headphone issues here:

1. Check for debris in the headphone port on your iPhone, iPad or iPod touch. 

2. Check your headphone cable, connector, remote, and earbuds for damage, like wear or breakage. 

3. 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. 

4. Firmly plug your headphones back in. If your iOS device has a case, remove the case to get a firm connection.

Thanks.
