A new word in science - micro-earphone
An earpiece is a small device that is inserted inside the ear and is used to silently receive speech. The device is installed in the ear canal, repeats its shape and is invisible to other people.

Microphones: what are they?
The micro-earphone has a mini-receiver design, which at the narrow end is placed in the ear, and at the wide end is equipped with a battery compartment. To get the device out, there is a fishing line at the end that you need to grab onto and pull it out of your ear. Operating time can be up to 10 hours, depending on the model.
A smartphone is required to transmit the audio signal. The headset is connected to it. The kit includes an induction loop in the form of a wire, which is worn around the neck or wrist.
Reference! To make the loop invisible, it needs to be hidden under a shirt or sweater. There is also a microphone included for communication.
Advantages of micro-earphones
The advantages of this device are obvious:
- Low cost due to ease of manufacture.
- Complete invisibility.
The disadvantages include:
- An amplified signal requires a powerful magnetic field, so severe headaches may occur after using the equipment.
- The rather large headset is noticeable on the body, so for complete invisibility you need to dress heavier.
What is the danger of micro-earphones
The device only touches the edge of the eardrum. This, as a result of prolonged interaction, causes its damage.
Attention! In addition, many questions arise regarding the ease of operation of the equipment, or more precisely, removal from the ear.
The ear canal is simply S-shaped. There is a narrowing in the center of the passage. Foreign objects that are caught in this narrowing can only be removed by a doctor. Moreover, this applies to smooth headphones.
For people who suffer from chronic ear diseases, the use of this miniature device is strictly prohibited, as it can lead to an exacerbation of the pathology and further formation of pus in the ear. And the proximity of the equipment to the eardrum, if it is defective, can lead to the earphone falling into the middle of the ear. In this case, medical intervention will be required.
That is, such an indicator as “price-quality” plays an important role when choosing a headphone. If you save once on purchasing this device, you can lose your hearing forever.
