Every student has heard at least once about “invisible” headphones that allow you to pass an exam. Still, the volume of information that is presented in modern universities is considerable, and the time to master the material is often not enough. Therefore, more and more students are turning to the achievements of scientific progress - micro-earphones for passing exams. With their help, you can get answers without arousing suspicion. What is a discreet earphone? This is a wireless device, a micro-radio receiver for covert communication. As a rule, a micro-earphone has the shape of a capsule. Such microequipment is placed in the ear canal, invisible to others and hidden from the stern gaze of the commission. In our online store in Moscow you can buy micro-earphones for exams from reliable manufacturers - the latest models are presented.

How to choose?

Microphones for exams vary in connection method. There are wired and wireless devices of this type.

Wired or hands-free headphones. The wired headset is equipped with a Hands-Free connector, easily connects to the phone and is low in cost. However, such micro headphones are not so convenient - you need to constantly keep your mobile phone in your pocket.

Wireless or bluetooth micro-earphones. Wireless models work via Bluetooth; you need to activate the module in the phone settings menu and connect mini headphones. In this case, the mobile phone can be kept at a distance of 10 m from the induction loop - for example, in a backpack or bag. These nano-earphones have excellent audibility and invisibility.

Micro-earphone-magnet

The smallest device designed for passing exams is a micro-magnet earpiece. Its dimensions do not exceed 1 millimeter. It is impossible to notice such an earphone (only if at an appointment with an ENT doctor), while the student easily receives answers to tickets from his assistant. However, this model cannot be called a safe micro-earphone. It's all about the principle of operation of the device. The magnetic earpiece does not have a speaker; sound is transmitted by vibrations, as it is located on the eardrum. The use of this microtechnology is not suitable for everyone and can harm health and reduce hearing. How to proceed? You decide!

Today we will be interested in micro-earphones for passing exams. This, according to many students, is wonderful and modern way, which will help you pass any subject with excellence. You just need to know how to use this device. After all, any mistake can lead to failure. Moreover, if we take into account the fact that there are different types micro earphones. There are not so many of them, but you can notice significant differences. How to choose a modern tool for cheating and passing exams? How does it work? What varieties are there? More on all this later.

What it is

First, let's talk about the fact that these are micro-earphones for passing exams. After all, it is not always clear what we are talking about. In our case, as you might guess, the device will be a very ordinary earphone. But only small sizes. It is used for passing exams and tests, since this device is not visible in the ear. It is placed deep and removed using a special magnet stick.

Basically, an exam earphone is an invisible tiny headset that connects to your mobile phone through which you can pass any subject. The main thing is that you have an assistant who will dictate all the answers. for passing exams are varied. What models can you find?

Wires

So, the first scenario is a wired headset. It will connect to your phone using wires. Usually these are the most ordinary headphones with a small base. It is attached to the body (usually on the back, under clothing) and then attached to the mobile device.

Next, the principle of operation is simple - you call (preferably in advance) your assistant, and then listen to the answers that are dictated to you. That is, if you think about how micro-earphones for exams work, you can answer extremely simply and easily - just like a regular telephone headset. But virtually invisible models are used for exams; it is extremely difficult to expose a person who is cheating. Almost impossible. Although wired models have their drawbacks. They are difficult to hide and not easy to use.

"Bluetooth"

Wireless headphones for taking exams are in great demand. This headset couldn't come at a better time. It is considered universal. In practice, it is precisely these models that help you pass exams and tests without any problems.

It's all about ease of use. After all, the headset will connect to a mobile device using Bluetooth technology. That is, no wires. These models are usually small circle-shaped tablets that are placed in the ear. This is the earphone. You could say it's a mini speaker.

Then you should call your friend and wait for an answer. You will be heard from the speaker of your mobile device, and you will be heard using a headset that is hidden deep in your ear. No wires or other hassles. The only problem is to hide the phone so that it is not noticeable. After all, the earphone itself cannot be seen in the ear even if one wants to - to remove it, you need to use a special magnetic wand. So if you are a beginner, or don’t want to spend a long time connecting a headset, choose wireless models. They will definitely bring success.

If necessary

Microphones for exams have their pros and cons. Just like any technology. Therefore o this device there are various. You can find both negative and positive opinions. It all depends on each situation as a whole.

However, first you must decide for yourself whether you really need a micro-earphone to pass the exam. Most often, students choose this path when there is simply no time left to memorize the material. Otherwise, it is recommended to simply make paper cheat sheets. Students have long learned to handle them.

But micro-earphones for passing exams (photos of which can be seen below) are a modern approach to solving the problem set before us. There are no problems with cheating; as they say, no one will find fault with you. The main thing is to practice in advance. After all, this is not such a simple process as it might seem at first glance.

pros

Well, micro-earphones for passing exams receive varied reviews. As we have already found out - both bad and good. This is quite normal. So you will have to study them. After all, not all students use this cheating option. Some people, on the contrary, prefer old methods and secrets.

However, you shouldn’t write off micro-earphones. Firstly, this is a fairly new tool that will help you cope with many problems. You can safely pass any subject with excellence, without being exposed.

Secondly, micro-earphones are available to everyone. There are, of course, expensive models, but there are very few of them. Basically, you can meet the cost of a regular phone headset. And this is a huge advantage for many students and schoolchildren.

Thirdly, sound quality. It makes a lot of people happy. You will hear your interlocutor perfectly, but you will not. More precisely, the teacher will not hear your conversation. That is, you don’t have to worry about this moment. It is almost impossible to be noticed.

Fourthly, one cannot help but highlight the time savings. Now you don’t need to spend your evenings writing cheat sheets or preparing for an exam. Simply connect the headset to your phone - and it is ready to use. Nothing difficult, even a primary school student can cope with this task.

Flaws

However, headphones for exams have their drawbacks. They force some students to stop using them, and also force them to leave negative reviews about the models.

Wired models have the worst reputation. They are difficult to hide, difficult to connect and difficult to use in general. Especially if you are going to an exam where the teachers have heard about the existence of mini headphones that can help you. Wired models are detected quickly, which makes them impossible to use.

Wireless ones are a little better, but they also have their drawbacks. Most often it is noted that the phone dies quickly when using this technique. This means that you will have to write down your answers and take the exam as soon as possible. Otherwise, you won’t be able to use the headset effectively.

It is also worth noting that for successful use you need an interlocutor. More precisely, a companion who will help you and answer your questions. This is a huge but obvious flaw. In addition, you will have to seriously prepare - learn to speak into a microphone so that the teacher cannot hear you, but your friend can easily hear you. Sometimes it's not that simple.

In some cases, micro-earphones for taking exams may cause some discomfort. You will have to get used to this, or stop using this technology. Most often, no consequences for hearing are observed, but you should try on the headset in advance.

Surprise

But there is one more small feature. It is currently being promoted in many regions and is directly related to micro-earphones for exams. The thing is that, as you might guess, you need to keep in touch for successful use headsets. With wireless models this is not a problem.

Only now many began to install special signal plugs in the classroom. That is, within a certain distance telephone communications it simply won't work. This means that the micro-earphone will not be of any help. This means that this is not such a universal remedy. Yes, the practice of using stubs is not so widespread yet, but it is already happening. This needs to be taken into account.

The perfect combination

How to be? Is it really not worth using earphones to successfully pass the exam? Not at all, you just need to find harmony in everything. We can give a little advice to all students about our topic today. Which one?

It is advisable, of course, to learn everything to successfully pass the exam. But this does not apply to cheating. If you want to enlist support and play it safe, specifically choose and also make regular cheat sheets. That is, combine both options for help on tests. This technique will definitely help you get out of any situation. And most importantly, do not forget, after purchasing a headset for the exam, to practice with it. Hone your skills in using headphones, only then go to take the subject!

Wireless headphones or micro-earphones are miniature devices that are inserted inside the ear canal and remain unnoticed by others. So, with its help you can secretly transmit speech and sound signals. These headphones are indispensable when taking exams, interviews and other critical cases.

What is included in the set with micro headphones?

The micro-earphones in the set of devices have a large loop antenna for wireless transmission sound vibrations. The loop is placed around the neck and connected to the source sound signals– mobile phone, MP3 player and so on.

The loop can be hidden under clothing. It does not cause any harm to health, since the electromagnetic field for transmitting vibrations to the headphones is very weak.

There are two types of micro-earphones:

In the form of miniature magnets. They are simply solid cylinders made of a magnetic alloy with a high content of the element “neodymium”. These tiny cylinders end up on your eardrum and, vibrating in time with the signals from the transmitter antenna, transmit sound vibrations directly without actually making any sound.

In the form of complex capsule devices(including Bluetooth devices). Capsule headphones, often called “nano headphones,” are more complex. They contain:
membrane (receiver of electromagnetic waves);
amplifier;
microspeaker;
battery for amplifier;
replaceable filter.

Capsule headphones are fragile and expensive, but they can be used for a long time, and they do not cause discomfort. These gadgets are removed from the ear using a special flesh-colored fishing line attached to the body. It is not recommended to drop such sensitive devices - very often after a fall they stop working normally.

Magnetic headphones are somewhat more popular than capsule ones, because their price is more affordable, they are not so delicate, you can replace a lost earphone quickly and inexpensively, and they do not require additional small batteries.

Connecting the antenna to a mobile phone can be wired (via a regular 3.5 mm jack) or via Bluetooth. In any case, you will need to somehow power the antenna. In older models of sets for micro-earphones, batteries of the Krona or Corundum type (“PP3” or “Brick Battery 9 V”) are used for this purpose. Newer models have a built-in battery on the antenna that can be recharged via a micro-USB connector.

You can clearly see the set of listed devices in the following diagram:

If two antennas for micro-earphones turn out to be nearby (for example, during the exam it turned out that your classmate also came with such a gadget, and even sat next to him), then problems are possible, especially if you have a simple magnetic micro-earphone. It will simultaneously respond to vibrations from both your antenna and your neighbor's antenna. To prevent this, try to stay away from each other.

The use of magnetic headphones is prohibited for children under 12 years of age; they may cause pain to the child, get stuck in the child's thin ear canal, or negatively affect normal hearing development. And adults are not recommended to carry a magnet for more than 2 hours at a time.

General instructions for using capsule micro-earphones

To use a capsule micro-earphone you need:

Insert the capsule into the ear.
Apply power to the loop antenna.
Connect the antenna to your mobile phone via a 3.5 mm jack.
Check the call quality by calling a friend or turning on music.
Adjust volume.

If hearing is poor, the reasons may be:

the speaker is partially or completely covered with earwax;
mobile phone set to low sound level;
batteries have lost the necessary normal operation charge level;
If you can hear music from your phone well, but can't hear the person you're talking to well, they may have problems with their microphone.

The speaker in a capsule earphone should measure approximately 2x2 millimeters or more. With such dimensions the sound will be quite clear and loud.

Also pay attention to the quality of the microphone in your headset. A microphone is usually attached to the induction loop, which is an antenna for the headphone. If your model does not have a microphone, you will have to buy an additional headset with a microphone if you need your interlocutor to hear you or the examiner’s questions. The microphone should be positioned at chest height so that your assistant on the other end of the line can clearly hear both you and what is happening around you.

The loop itself should be on your neck, closer to the receiving device. If it ends up in your pocket or in a curled state, its low power may not be enough for the set to operate normally.

If necessary, set your mobile phone in advance to automatically receive calls without sound or display on the screen. This function may be needed, for example, during an exam.

To ensure that your device lasts a long time, try to follow these rules:

Do not let the earphone fall. After sudden impacts, the sound quality will become much worse or it may stop working altogether.
Before using the earpiece, clear any wax from your ear canal, otherwise the sound may be too low due to the wax layer that has coated the speaker.
Do not forget to remove the batteries from the earphone and antenna if you are no longer using the gadget. It is worth noting that so-called “clock” alkaline batteries of the “Go” or “LR52” type are used to power the capsule headphones. They are enough for 7-8 hours of continuous operation.

Do not give the capsule to children - the examination may well end in ingestion, injury to the child’s ear, the device falling, or simply getting lost.

How to replace the battery in a capsule micro-earphone?

Typically, the power supply compartment is located on the wider part of the earphone, that is, on the opposite side from the speaker. To prevent the battery from accidentally falling out of the device, it is held in the clamps quite tightly. Therefore, it will be necessary to insert and remove the battery with little effort. Clips are often made of stainless steel or even silver to avoid corrosion and ensure reliable contact with the battery.

Instructions on how to insert batteries into the device are as follows:

Find a suitable place to handle the battery - a wide, flat and soft surface on which both the earphone and the battery will be clearly visible, and there will be no danger of hitting the earphone too hard. Some people do this operation on a bed with a white sheet, others on an ironing board, and many place a white blanket on the table.
If there is an old battery in the earphone, remove it using a thin, sharp object. It’s good to use a straightened paper clip for this. It is better not to take sharp awls or similar tools: there is a danger of injuring yourself and also accidentally damaging the earphone.
Insert the new battery in place of the old one. Don't mix up the polarity!
Check the functionality of the device.

It’s better to take a new battery for each new important occasion when you use an earpiece, otherwise a situation may suddenly arise when you lose contact with your assistant, and it’s time for you to answer or continue the report.

How to insert a magnetic earpiece into your ear?

With capsule-type micro-earphones everything is simple and intuitive; they are inserted into the ear as usual, but with magnetic ones it’s a little more interesting.

To place the micro-earphone in the ear, one tool is used - a plastic tube. A micromagnet is placed in it, and then falls out of the tube into your ear.

detailed instructions How to insert a magnetic earphone into your ear is suggested below:

Clean your ears as thoroughly as possible before using the earpiece. If it ends up covered in a thick layer of sticky earwax, the magnetic wand won't be able to remove it from your ear. You will have to contact an otolaryngologist.
Before you begin the procedure of “throwing in” the earpiece, you can turn on any music on your mobile phone. This way you will immediately understand that you have installed the earphone correctly - if you hear music, then everything is in order.
Before inserting the tube, sit so that no one can disturb you, and so that you do not disturb anyone. You should not do this standing or lying down.
Insert the tube into your ear approximately 2/3 of its total length. You don’t need to insert it too hard or sharply, otherwise you may injure yourself. The sensations when a magnet gets into your ear are very similar to those you experience when water gets into your ear canal while swimming.

It is best to insert the tube yourself, without having someone else do it, because only you can feel when the tube goes easily into the ear canal or when it hurts.

Once the tube is in your ear, make a slight tilting movement with your head. You need to tilt your head to the side sharply enough so that the magnet drops to the desired depth by inertia. However, be careful not to hit furniture or people nearby.

Magnetic headphones “slip into the ear over the eardrum. This organ of hearing tolerates short-term exposure well, but long-term exposure - not so much. To avoid problems, strictly adhere to the maximum time for using headphones - no more than 2 hours!

The video below demonstrates how simple and practical it is to use the magnetic earpiece:

To remove the earpiece, you need another tool - a special stick with a magnet at the end. Sometimes both of these functions are performed by one combined elongated structure.

Bluetooth headphones and rules for their use

Bluetooth micro-earphones have the following advantages over conventional capsule ones:

no wire needed from the mobile phone to the antenna loop;
The loop antenna is powered by a built-in battery with USB charging, so there is no need to store or change Krona batteries;
you can use several wireless headphones, quickly switching between them from one mobile phone or, conversely, alternately connecting to the earphone from different mobile devices;
There is a connection indicator on the Bluetooth antenna receiver mobile device, thanks to which you always know that the connection is established.

Typically, Bluetooth headphones use a Chameleon LR521 battery.

On the electronics market you can purchase an advanced Bluetooth device, in which the frame of glasses acts as an induction antenna. Their body contains a battery, a Bluetooth receiver, and a sound vibration transmitter.

The short video clearly shows the process of connecting and using a bluetooth micro-earphone:

Don't forget to check the charge level of your mobile phone before using bluetooth headphones. If the phone's battery is low, the transmitter will also not be able to work.

Various technological breakthroughs are happening around us continuously. Microphones are one of them. These are irreplaceable devices that can help you in the most difficult and critical situations; the main thing is to prepare in advance and master the rules of how to use them.

In contact with

It’s worth taking a closer look at some of the features and techniques for installing various types of micro-earphones in your ears.

Since users of these devices often prefer to rent them, it is not always possible to become familiar with the requirements in sufficient detail to ensure reliable and safe use such kits.

Installation Methods

Despite the variety of models, only the methods used for capsule and magnetic devices are fundamentally different.

The kit functions as follows:

Communication with the subscriber is provided through a mobile phone, which is synchronized with the headset.
The information received from the phone is converted into electromagnetic waves in the headset. For this, a special antenna is used, from which the signal arrives at the receiver.
So the user gets audio information completely invisible to others.
To implement feedback remote microphones or microphones built into the headset body are used, miniature cameras or cough buttons.

Some manufacturers produce headsets for micro-earphones, which are disguised as everyday items: watches, pens, glasses, etc.

This significantly increases the secrecy of using communication kits, but, in some cases, negatively affects the sound quality.

Benefits of using. Features and rules of operation.

In the next one we will tell you how to make a device for hidden communication with your own hands

Read here how to properly charge the earphone before starting work.

Special attention should be paid to rules for installing a device in the ear.

For capsule devices

Capsule models are distinguished by a more familiar shape and internal structure to the user. Their body resembles a small flesh-colored capsule, the length of which ranges from 5 to 13 mm.

Features of installing a capsule micro-earphone not so much in the ear:

Before each use of the device, you need to replace its battery, since a new battery lasts only 5 hours of operation.
The capsule is inserted into the ear canal with your fingers, gradually screwing it as deep as possible into the ear.
If pain or discomfort occurs in the hearing organs, you must immediately remove the device using a special fishing line, which is attached to the back of the case.

After installing the capsule at a sufficient depth, it is worth checking how invisible its location is to others.

Ideally, the earpiece should not be visible at all.

For magnetic cylinders

Magnetic analogues are miniature cylinders, the diameter of which is only 2-3 mm.

A magnetic micro-earphone is placed directly on the eardrum. Under the influence of an electromagnetic signal coming from the headset antenna, the magnet vibrates and transmits vibrations to the eardrum, which are perceived by the human brain as sound.

Installation of magnetic devices is a more complex procedure:

For this purpose, a special device is used - an ejector tube. It has a clamp at one end that grips the magnet.
After inserting the tube deep enough into the ear, it unclenches and the magnet freely falls onto the eardrum.
In this case, the head should be held so that the ear into which the cylinder is installed is located on top.

When installing a magnet, it is normal to experience unpleasant sensations that resemble ear congestion when water gets into it.

If this feeling does not go away for a long time, you need to remove the device and reinstall it. Also, re-installation is necessary if the magnet is not installed tightly and moves in the ear canal when moving.

To remove the magnet, a special magnetic stick is used, which is inserted into the ear in order to attract the cylinder to itself. This process is accompanied by a loud click, upon hearing which you need to carefully remove the device from your ear.

For detailed instructions on how to insert a magnetic earpiece into your ear, watch the video:

Before each installation of a micro-earphone, you need to perform hygienic procedures to clean the ear canal from wax.

This will help not only avoid health problems, but also significantly improve sound quality.

To summarize, we can say that Easier to install and safer to use capsule device models.

However, if it is necessary to ensure maximum secrecy of use, then the best option are micro-earphones-magnets.
