My iPhone 6S Headphone Jack Is Shorting Out My Headphones

Check for debris, damage, or loose connections

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.

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

1. Adjust the volume with the volume buttons on your iOS device or use the Volume slider in Control Center.
2. 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.

My son had an issue with his iPhone 6 where the headphone jack started to flake, then stopped working entirely. I discovered that the $9 Lightning to headphone adapter designed for the iPhone 7 actually works on the iPhone 6/6S. Run to Wally World and pick up the adapter and see if your previous and current headphones continue to work. it worked for my son :-)

Since our phones were eligible for an upgrade at Verizon, the 4 of us all upgraded to the iPhone 7 (128GB). Problem solved :-)
