A:Answer These aren't something you would want to "try" in the store. You need to take them home, fit them, set them up, and be amazed at what they can do. You do need to wear them in different settings to really see the full benefits of them. I do believe they are returnable within a certain number of days, but if you try them and hear what they can do, I dont think you will want to return them. I wear them in a busy restaurant with loud music playing , and I can still hear what my family is saying at the other end of the table.
