Spy earpieces are available in three types – bluetooth spy earpieces, mp3 spy earpieces and ordinary wired ones. The first (bluetooth spy earpiece) and second (mp3 spy earpiece) types are most widespread and popular.
Prevailence of bluetooth spy earpieces is determined by steadily growing popularity of Bluetooth standard of wireless data transmission in GSM mobile phones – Bluetooth service can be found virtually in each GSM mobile phone. One can explain why Bluetooth spy earpieces are in great demand in each educational institution – such devices offer students easier ways of personal development and opportunity to achieve magnificent results at examinations. Bluetooth spy earpiece gives all this quickly, cheaply and easily!
We may see in the technology of Bluetooth spy earpiece the future in new methods of quick reception of the audio information from any area – with the help of GSM mobile phones and invisible spy ear pieces. Your partner transfers the information you need to your GSM mobile phone which is further transferred by means of Bluetooth technology to the Bluetooth spy earpiece plugged in your ear. Simultaneously, your partner can hear your replies using invisible microphone.
Let’s consider no less successful decision – mp3 spy ear pieces. The main advantage of mp3 spy earpieces is that you needn’t to attract the partner to this process. You can record all important information in advance on your mp3 device and listen later when it is necessary! Since you are familiar with your own voice and record contents, it will be easier to understand and analyze audio information.
As to the last kind – wired spy ear piece, it is a bit out-of-date approach to the problem. Usual wired earpiece does not differ from Bluetooth one except that the micro earpiece is communicated to the GSM mobile phone by wire, often inconvenient in use.
