Where are the headphones talking?

That is, after wearing headphones, talk close to the chin and lips, and the other person can hear you. The plus sign and minus sign on the earphone control key represent the increase or decrease of volume, and the button can answer the hung-up call.

When using headphones, you should adjust the volume of headphones and use the same volume setting. Listening to songs or movies with headphones is louder than listening to the sound box, which will stimulate the eardrum. Adjust the volume of headphones to a comfortable level to avoid hearing damage.

When using headphones, you should distinguish between left and right, L stands for left, wear left ear, R stands for right and use right ear. The effect is most obvious when users watch movies, and the sound of left and right channels has its special effects. For example, if the plane flies from far to near to the right, the sound on the right will be louder, and finally it will be on the left.

Precautions:

Adults should not use headphones for more than 2 to 3 hours a day, and should avoid continuous use for more than 60 minutes. The volume should be controlled at 40-60 decibels (generally a little lower) to feel comfortable and happy. Of course, the less time you spend using headphones, the better.

Remember to adjust the volume from small to large when choosing the volume, so that your ears can adapt to the volume slowly. Don't turn it up at once, it will do great harm to your ears. Once you choose the right volume, don't increase the volume, otherwise it will increase the hearing burden on your ears.

Don't resist the noise of the surrounding environment by raising the volume, such as taking buses, subways and noisy streets. Listening to music in noise is the most harmful to hearing. At this time, the external sound is usually about 70-80 decibels, so it is easy to hear music playing at a high volume, which is easy to exceed 100 decibels, causing serious damage to the ears unconsciously.
