If you’re looking to increase your ear volume on your iPhone 6, there are a few things you can do. First, make sure your phone is set to " louder" mode. This will reduce the amount of sound that is heard by other people in your conversation. Second, try using an earplug or noise-cancellation headphones if you can’t live without them. Finally, if you’re still having trouble hearing people in your conversation, try increasing the size of your phone’s speaker.
