The earpiece is a miniature device designed for covert information transfer. It is inserted deep into the ear canal and is removed using a fishing line or ejector. This technology was developed to support secret services, but over time it became public. Now wireless earphones are increasingly used by students to take tests and sessions. This is very convenient if there is no way to learn the subject yourself. Today we will tell you how the headphones work for passing exams and what you need to consider when choosing them.

Types of headphones for the exam
The earpieces can be divided into two large categories: capsule and magnetic. They, in turn, differ from each other in size, method of sound transmission, extraction method and price. For the device to work properly, you need a signal receiver, which is a smartphone, as well as a special pendant headset consisting of a miniature microphone and antenna. Most headsets are wireless and connect to the receiver via the Bluetooth module, but there are also wired models that are not inferior to the quality of sound transmission.
Capsule
Capsular earplugs have a cylindrical body shape and resemble ordinary earbuds. Removed from the ear with tweezers or fishing line. They are universal and can be connected to any type of headset. The smaller the size of the "capsule", the higher the cost (the smallest are called nano-devices). The principle of the headphones is the conversion of electromagnetic waves into vibrations of the sound membrane. To increase the sensitivity, an amplifier is used that runs on battery power. Capsule devices are much safer than magnetic ones, but they are easier to detect.
Magnetic
The magnetic earpiece is in the form of a tablet that attaches to the eardrum. It is removed using an ejector - a special tube with a magnetic tip and clamp. Typically, the size of the "tablet" is from 2 to 5 mm. The principle of operation is simple: the electromagnetic signal from the headset is converted into vibration, and then transmitted to the eardrum. Our brain perceives them as sound vibrations and turns them into speech. Magnetic headphones do not require the use of batteries, so their autonomy depends only on the smartphone and headset.
Which headphone is better - capsule or magnetic
From a safety point of view, capsule earplugs are the best because Do not damage the eardrum when using them. They are easier to remove from the ear canal and are cheaper. But, despite all the advantages of capsules, magnetic devices are smaller, sit quietly in your ears and do not require a constant change of batteries. The conclusion from this can be drawn as follows: each species has its pros and cons, so you should only orient yourself by your own preferences and capabilities.
Features wired and wireless headphones for the exam
There are two types of earpieces - wireless and wired. The first appeared wired models that connected to the receiver with a thin cable. They are still used by security organizations and police officers. The main advantage of wired earplugs is autonomy. They are powered by the smartphone’s battery and do not require a constant change of batteries. However, this also has a drawback: the cord is difficult to hide. If you have short hair, then there is no question of stealth.
Wireless headphones connect to the receiver using a Bluetooth module or radio. The transmitter is a headset, which can also be wired or wireless.The main feature of such devices is stealth. The small size of the headphones allows them to go deeper into the ear canal, so they are more in demand among students.
Advantages and disadvantages of the earpieces
Like any technique, earpieces have their advantages and disadvantages. More about them:
Benefits:
- No need to memorize a huge pile of information to pass the exam. Trite, but for the sake of this, most earphones are acquired. It is enough to ask someone to dictate the answer, and the offset in your pocket.

- You need to constantly buy batteries. When choosing “capsules”, batteries must be changed every 8-10 hours, and this is an additional cost.
- High price. Earpieces are two to three times more than ordinary headphones.
