I would think Apple is the company you should contact since THEY included them with the device.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
You can call Verizon since earbuds are included in standard warrenty unlike other phones. Vzw has them as we'll as the earpods which are better construction. Ear buds sometimes comes apart for me. Apple won't do anything unless you go to the store
Unless Apple changed it, you can contact them via telephone (go to the website and schedule a call back) and they will replace the defective ear buds.Go to the following link and choose iPhone, Service Requests & Troubleshooting, and continue through to select earphones. https://expresslane.apple.com/Issues.action
