You’d think that the American FBI (being the United states FBI and all) would have access to an earpiece a bit cooler that just the common ‘curly cable’ job, wouldn’t you?
If pushed, I’ve to state that I tend to imagine a little old fella, like Desmond Llewelyn in the Bond films, (and even a younger example like Ben Whishaw from ‘Skyfall’) producing all the gadgets himself after which explaining them to the agents before they go out and protector the President’s life.
This is simply not the case. They use the versions that they use because they work and they work well. Essentially, wired models are still more reliable than their wireless counterparts. With wireless, you tend to have more interference, as well as needing to contend with more limited bandwidth. Basically, you will need dependable tech if you’re in the field. Lives are at stake in a number of cases.
This simple, trusted earpiece might be relied upon to do the job, every time.
Another advantage that wired earpieces have over wireless ones (in this example, at least) is the proven fact that a wired set needn’t take an additional battery. Wireless earphones would require charging and, as a consequence, would possess a somewhat limited operational capacity. It just causes a lot more headaches for individuals who, let’s face it, previously possess a good bit on their plates to start with.
According to ‘AskJeeves.com’
“The ear piece and mic that the secret service uses is called a Throat Mic. The Throat Mic has clarity that is unsurpassed, great sound quality, and allows for discreet interaction. It also has an acoustic air tube that makes it comfortable when worn for long periods of time”.
The ‘curly earpiece’ tech is actually rather popular and is used by a number of individuals and organisations beyond the FBI. You can even buy a wireless version, but don’t expect the secret service to be interested!
I might argue another point, but this is merely a pet theory with very little research to back it up. Psychologically speaking, when y’see a secret service agent, you identify them as such without observing them in any kind of uniform (beyond a suit, shades and an earpiece), the headset, then, is really a subtle reminder to you, the civilian, that not only is this not a regular person in a suit, but additionally the area where you now find yourself is being closely monitored.
With one remark to his/her earpiece, the agent in question can almost certainly call down all the other agents in the direct area, also as police, fire brigade and anyone else he/she believes is essential. That subtle reminder is likely an extremely powerful crime deterrent. No guns need to be displayed, no helmets or flak jackets worn and yet y’know that this person has eyes everywhere and could, potentially, really ruin your week. As I said, it is just a assumption, but It looks like it makes sense.
