Q: iphone 6 no sound except with head phones

Hello anunevadacity,

After reviewing your post, it sounds like you do not have sound from the receiver. I would recommend that you read this article, it may be able to help the issue.

If you can't hear a person on a call or voicemail or if the sound quality is poor on iPhone - Apple Support

Thanks for using Apple Support Communities.

Have a nice day,

Mario
