The metal ear canal should be tilted forward and put into your external auditory canal, so that the ear sinus and your ear canal are close together; Everyone's ear canal size is not the same, you can choose the appropriate size of the ear sinus. If the wearing method is correct, but the ear sinus and ear canal are not close enough, and the auscultation effect is not good, please pull the ear canal to adjust its elasticity. Improper wearing method, ear sinus and ear canal is not close when the auscultation effect is not good. For example, if you put the tube on backwards, you can't hear at all.
  Remove debris: cotton wool, fiber, or dust from clothing can clog the ear canal of a stethoscope if it is left in a pocket or not maintained regularly. Regular maintenance and cleaning can avoid these situations.
