How do you decide earbud tip sizes?

To decide on earbud tip sizes, start by trying the different sizes that come with your earbuds, as they often include multiple options. A proper fit should create a snug seal in your ear canal without discomfort, which helps enhance sound quality and passive noise isolation. If you're unsure, consider using a sizing guide or measuring the diameter of your ear canal. Ultimately, comfort and sound quality should guide your choice.
