What is earwax supposed to smell like?

Normal earwax is typically odorless or has a mild scent. However, if earwax has a strong, foul smell, it may indicate an infection or an underlying issue. Foul-smelling earwax can be caused by bacteria or fungi, and should be examined by a healthcare professional. Additionally, if earwax smells sweet or fruity, it may indicate a rare metabolic disorder called "maple syrup urine disease." In any case, it is important to seek medical advice if there are any changes in the smell of your earwax.
