You would think that the U.s. FBI (being the American secret service and everything) would have access to an earpiece a bit cooler that just the standard ‘curly cable’ job, wouldn’t you?
If pushed, I’ve to state that I usually imagine some old fella, like Desmond Llewelyn in the Bond films, (or even a younger model like Ben Whishaw from ‘Skyfall’) producing many of the gadgets himself and then explaining them to the agents before they go out and guard the President’s life.
This is just not the case. They use the versions that they use because they work and they work well. Basically, wired models are still more dependable than their wireless counterparts. With wireless, you tend to get more interference, as well as needing to deal with more restricted bandwidth. Essentially, you will need reliable tech if you’re in the field. Lives are at stake in some cases.
This straightforward, trusted earpiece might be relied upon to accomplish the job, every time.
Another advantage that wired earpieces have over wireless ones (on this example, at the least) may be the fact that a wired set needn’t take an extra battery. Wireless earphones would need charging and, as a result, would possess a somewhat limited operational capacity. It just causes a whole lot more headaches for people who, let us face it, already 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 utilized by a number of individuals and organisations beyond the FBI. You are able to even buy a wireless version, but do not expect the secret service to be involved!
I might contend another point, but this is merely a pet theory with little or no research to back it up. Psychologically speaking, when you see a secret service agent, you recognize them as such without seeing them in any kind of uniform (beyond a suit, sun glasses and a radio earpiece), the headset, then, is a subtle reminder to, the civilian, that not merely is this not a regular person in a suit, but also the area in which you now find yourself is being closely monitored.
With one remark to his/her earpiece, the agent in question can almost certainly call down many of the other agents in the direct area, also as police, fire brigade and anybody else he/she believes is necessary. That subtle reminder is probably a very potent crime deterrent. No guns need to be displayed, no helmets or flak jackets worn and yet y’know that this person has eyes all over the place and could, potentially, really ruin your week. As I said, it is merely a theory, but It looks like it makes sense.
