Today we will be interested in micro-earphones for passing exams. This, according to many students, is an excellent and modern way that will help you pass any subject with excellent marks. 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 taking 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, they simply won’t find fault with you, as they say. 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 it at the 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 schoolboy primary school will 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, making their use impossible.
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 your 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 maintain communication to successfully use the headset. 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 communication simply will not 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!
The hidden earpiece is used by students to answer questions during exams. This technology came to us from the world of intelligence. In addition to providing tips for studying, the devices can also be used when playing sports.
Mini headphones work according to the usual headset principle. For them to function, you need some kind of mobile device and a person to transmit the necessary information. The only difference from the headset is their size. The headphones are so small that they are difficult to detect from the outside.
Types of headphones. In the typology of headphones, the variety of models is not large. It makes sense to divide spy headphones for exams according to the type of their connection with the source of signal reception, that is, with the phone.
There are two types of mini headphones:
- Wired headphones are connected using wires that are hidden under clothing. Not the best convenient way: carefully hiding the wires is not so easy;
- wireless, communicating with mobile device via Bluetooth. They are completely immersed in the ear, as they are the size of a small metal tablet.
Of these two types of headphones, choose the one that is more suitable for each situation. A mini earphone for an exam has its advantages, the main one being its size. It's really not that easy to spot. The sound is only audible to the person using them. The price is not much higher than a regular headset.
Hidden Bluetooth headphones are more preferable when taking exams, but we must remember that such headphones are harmful to health because they are located too close to the eardrum.
Wired headphones have significant disadvantages - the inability to carefully hide the wires. The wireless one is much better, however, the hidden wireless earbud quickly drains the battery with intensive use. In addition to the above, you need a friend with whom you will communicate, which means you need preliminary training - after all, no one should hear the conversation during the exam.
How to choose a headphone?
When buying spy headphones, you should pay attention to the main points that make working with these devices the most convenient and safe. Headphones are not that complicated, but knowing the criteria for their selection, you can immediately buy something that will really help with your studies.
Basic rules for choosing headphones:
- the size should be as small as possible;
- The battery in the earphone is located at the end, this also affects its size and shape.
One important circumstance must be taken into account: these devices are very fragile, they are easily damaged, and then difficult to fix.
The hidden earpiece is used by advanced students. Teachers already know about such technologies, so it is quite possible to use jammers, especially for technical universities.
In such cases, it makes sense to use walkie-talkies instead of phones. But their use has a significant drawback - they are larger in size than mobile phones and are not easy to hide.
Mini headphone models
Manufacturers offer a number of models of such headphones, which are used not only for studying, but for playing sports, as they do not interfere with movement at all. Next, we will consider the three most popular models.
Stereo S530 Bluetooth, the size of this earphone is 1x0.6 centimeters, it fits perfectly in the ear. The battery, with active use, holds a charge for up to 4 hours, turning on and off with one touch of the earphone.
2017 Fashion Mini bluetooth, its size is 1.5 centimeters, it is inserted into the ear like a plug and attached to the auricle with a hook. Perfectly controlled by touching your finger. In the active phase it can work for two hours.
A micro-earphone is a miniature device designed for covert transmission of information. It is inserted deep into the ear canal and removed using a fishing line or ejector. This technology was developed to support the secret services, but eventually became public knowledge. Now wireless earphones are increasingly used by students to take tests and sessions. This is very convenient if you cannot learn the subject yourself. Today we will tell you how headphones for exams work and what you need to consider when choosing them. Microphones 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 full operation of the device, you need a signal receiver, which is a smartphone, as well as a special headset-pendant, consisting of a miniature microphone and antenna. Most headsets are wireless and connect to the receiver via a Bluetooth module, but there are also wired models that are not inferior in sound quality. Capsule micro-earphones have a cylindrical body shape and resemble regular earbuds. Removed from the ear using tweezers or fishing line. They are universal and can connect to any type of headset. The smaller the “capsule” dimensions, the higher the cost (the smallest ones are called nano-devices). The principle of operation of headphones is the conversion of electromagnetic waves into vibrations of the sound membrane. To increase sensitivity, a battery-powered amplifier is used. Capsule devices are much safer than magnetic ones, but they are easier to detect. The magnetic earphone has the shape of a tablet that is attached to the eardrum. It is removed using an ejector - a special tube with a magnetic tip and a clamp. Typically, the dimensions of the “tablet” range from 2 to 5 mm. The principle of operation is simple: the electromagnetic signal from the headset is converted into vibrations 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. From a safety point of view, capsule micro-earphones are the best, because... When using them, you cannot damage the eardrum. They are easier to remove from the ear canal and are cheaper. But, despite all the advantages of capsules, magnetic devices are smaller in size, sit more inconspicuously in the ears and do not require constant battery changes. The conclusion from this can be drawn as follows: each type has its own pros and cons, so you should be guided only by your own preferences and capabilities. There are two types of micro-earphones - wireless and wired. The first to appear were wired models that were connected to the receiver with a thin cable. They are still used by security organizations and police officers. The main advantage of wired headphones is autonomy. They are powered by a smartphone battery and do not require constant battery changes. However, this also has a disadvantage: the cord is difficult to hide. If you have short hair, then inconspicuousness is out of the question. Wireless headphones are connected to the receiver using a Bluetooth module or radio communication. The transmitter is a headset, which can also be wired or wireless. The main feature of such devices is secrecy. The small size of the headphones allows them to fit deeper into the ear canal, which is why they are more popular among students. Like any technology, micro-earphones have their advantages and disadvantages. More details about them: Advantages: Flaws: There are many models of spy headphones on the audio market. But only 5% of them are truly safe and high-quality devices. We've compiled a list of the best mini headphones for exams to make it easier for you to choose:Capsule

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?
Micro-earphones in the set of devices have a large loop antenna for wireless transmission sound vibrations. The loop is worn around the neck and connected to a source of sound signals - a 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 with them 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;
- the mobile phone is set to low volume;
- 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 the 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 “watch” 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 swallowing, injury to the child’s ear, falling of the device, 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 is 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 device's functionality.
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 micro-earphone, you can turn on any music on 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 connect to the headphone from different mobile devices;
- There is a connection indicator with a mobile device on the Bluetooth receiver of the antenna, 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. Micro-earphones 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.
