SpySystem Device - Earpiece
In my practice I deal with a micro earpiece. A very useful device for a certain segment of people. The purpose of this mini -review is to familiarize people who do not know about the existence of a micro-earphone with this device.
Let's start with the fact that we stipulate the size of the earpiece. This earpiece is most often a flesh color and falls through the ear. It is not visible if properly installed. That is, with these two sentences, I wanted to say that these are not the headphones that are shown in the films, where the swirling wiring from Soviet phones hangs from the agents' ear.
Schematic diagram of the work. Let us analyze in words. A headset with a battery (AG0 or LR521) receives the signal from the antenna (loop on the neck). The antenna directly connects to the phone. A microphone is also removed from the phone and placed on any part of the body. It is easy to guess that the antenna and microphone can connect with the phone and through bluetooth. Therefore, there are 2 lines of devices: <name> and <name of BT> differing only in the method of communication between the phone and the periphery.

Cheaper and earlier versions still had a signal amplifier, which was made from Manbo Mono Radio Scanners. They have lost their relevance, this is where the conversation about them ends.
There are versions with a walkie-talkie included, with a range of 3 km. But the phone is better, for communication with any point of the planet in principle.
Also, there are a lot of manufacturers themselves loud headphones - quality and not very much. But everyone works.
The microphone is very sensitive. All voices and taps are heard. At this moment I’m holding this version in my hand:
This version is for Nokia phone. The micro earphone itself, measuring 10.5 x 4.5 x 4.5 (mm), has a centimeter fishing line, for which it must be pulled out of the ear.
Batteries in the earphone lasts for 4-5 hours. The battery in the phone sits as usual.
In order for the passenger outfitted with this device to display high-quality knowledge and intelligence in interactive communication, a clever “radio operator” is needed first and foremost. Smart does not mean erudite. In this case - just active and attentive, in some sense, perhaps, Homo Sapiens.
Separate communication skills through this thing can be presented in another topic, unless, of course, habrareyd find it at least a bit useful.
This is my first contribution to Habrahabr. I tried to put it shorter.
Thanks for attention.
