This is an unpopular opinion. You can train yourself to work in relatively noisy environments. The mind is plastic and adaptable. It is not going to happen right away. The first step is to not plug in your headphones when you go to a coffee shop. Enjoy the ambient chatter. Don't try to do any work. After a while, you may try reading a book or a newspaper. It is my belief that headphones can breed dependency on them to focus. Kind of like you may be anchoring your flow state to the simple act of donning your headphones. It might not work for you. Especially if you pre-decide it won't work. Remember the mind is a powerful tool. It may work for you if you start trying out life without headphones.
