Assuming you didnât make your own spy earpiece (we ran an instructional piece on how to build one last year), there are three main types of spy earpiece.
- Bluetooth spy earpieces
- Mp3 spy earpieces
- Wired spy earpieces
The appeal of the spy earpiece is simple (and goes beyond simply having the word âspyâ in the title). A spy earpiece is largely invisible to the outside observer, allowing the user to send and receive information in a discreet and covert manner. In recent months, spy earpieces have skyrocketed in popularity. According to this blog entry we sourced,
âWe 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 microphoneâ.
The Bluetooth spy earpiece is the most diverse of the three types. Using a Bluetooth spy earpiece, it is possible to relay messages and information between two users. In this fashion, these earpieces are now being used in business presentations and high-pressure working situations, when up-to-the second information is necessary for completion of a task.
The Mp3 spy earpiece is a little different. It can only play back audio information (it has no send/receive functions). However, it still proves to be a popular choice, as this Blogspot confirms,
âThe 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 informationâ.
The final type, the âwiredâ spy earpiece, is probably the least popular of the three. Itâs not difficult to see why; the wire renders the earpiece awkward and conspicuous. Despite wired technology still having a (general) advantage over wireless in terms of transmission speed and reliability, spy earpieces are one technological avenue that needs to attract as little attention as possible to itself (the operative word being âspyâ) and a wired earpiece just doesnât camouflage as well as a wireless one.
On this, the blog says,
âIt is a bit (of an) out-of-date approach to the problem.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 useâ.
Â The Bluetooth spy earpiece is definitely the best choice in terms of versatility.
