In-ear headphones, also known as ear-canal headphones, in-ear earplugs, or in-ear monitors (ie, the full English name of IEM: In-Ear-Monitor), are earphones used
inside the human auditory organ. According to its design, Will seal the user’s ear canal during use. It can eliminate external noise interference, the sound quality is
full and clear, and it is light and easy to carry. But people often complain that the headphones are too small and the bass part is insufficient, and they often fall
out. Next, I will talk about the correct way to wear earphones for your convenience.
1.For better sound performance, the earmuffs and the ear canal must form a good airtight environment. Therefore, we must first confirm the airtightness and strive to
istinguish between the left and right earphones.
2.In order to better enable the earphones to enter the ear canal, use water as a lubricant.
3.Correspond to the correct ear canal, pick up the earphones and start putting them in your ears.
4.Gently place the earphones in the ear canal.
