You would believe that the U . s . secret service (being the United states secret service 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 say 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 devices himself after which 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 they use as they work and they work well. Essentially, wired models continue to be more dependable than their wireless counterparts. With wireless, you tend to get more interference, as well as having to contend with more restricted bandwidth. Basically, you'll need reliable tech if you’re within the field. Lives are at stake in some cases.

This straightforward, trusted earpiece can be relied upon to do the duty, every time.

Another advantage thatwired earpieces have over wireless ones (in this example, at least) may be the fact that a wired set needn’t carry an additional battery. Wireless earpieces would require charging and, as a result, would possess a somewhat restricted operational capability. It just causes a lot more headaches for people who, let’s face it, already have a good bit on their plates to start with.

“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 generally rather common and is utilized by a variety of people and organisations beyond the secret service. You can even buy a wireless version, but do not expect the FBI to be involved!

I could contend another point, but that is just a pet theory with little or no research to back it up. Psychologically speaking, when you see a FBI agent, you identify them as such without observing them in any form of uniform (beyond a dinner 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 inside a suit, but additionally that the area where you now end up is being strictly 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 likely an extremely potent crime deterrent. No guns need to be displayed, no helmets or flak jackets worn and yet you know that this person has eyes all over the place and will, potentially, really ruin your week. As I said, it is merely a hypothesis, but It looks like it makes sense.
