how do I use earphones with iphone
I am a grandmother who doesn't use all the apps that are on the iphone. I am planning a nice vacation where I will be flying quite a lot. Please tell me how to use noise cancelling earphones with my iphone. If I download an audio book, will I be able to listen to that on the plane. I also have an ipad, can I use the earphones with that as well. I had such a bad experience on my last trip with screaming babies on international flights. Thanks
