To deal with students who want to get help on the exam using mobile communication, various methods are used, the most common of which are jammers. Their main function is to suppress the signal coming to the phone. This measure is used, among other things, to prevent the use of such a gadget as a micro-earpiece complete with a mobile phone.
If the building has "jammers" of GSM-signals of mobile phones, then this is not a hindrance for the walkie-talkie at all. A hands-free headset with a microphone is attached to the walkie-talkie. The second walkie-talkie is located with your partner, who can be up to 15 km away from you in the line of sight, and in the city, depending on the thickness of the walls in the building where you are located, up to 1-2 km.
The set includes 2 walkie-talkies. From the second to the first, the necessary information is transmitted, which is transmitted to the headset. There, it is converted into an electromagnetic signal and transmitted further — to a miniature earphone located in the ear. At the receiver, the signal is converted back to audio.
You put our 12x5x5mm PICO CHINA capsule micro-earpiece in the ear hole, and you can communicate like a normal phone, just don't need to hold the phone to your head. The back of the micro-earpiece goes for an invisible tendril. Each micro-earpiece has a color and size, depending on which it is determined by its visibility or invisibility in the ear canal.

Chinese earpiece kits are easy to distinguish, knowing a few things. Chinese headphones - plastic. They work on a single battery for no more than 1.5 hours, despite the 12-15 hours that are written on different sites. The main disadvantage of Chinese micro - headphones is that 90% of them fail within 1 year. The speaker demagnetizes and the earpiece fades out. Chinese bluetooth devices are of very poor quality, with weak and unreliable batteries and microphones with low sensitivity.
