How Large are the Batteries in a Typical Bluetooth Earpiece?

The size of the battery actually depends on the Bluetooth earpiece. Some of the more basic earpiece models run on a single AAA battery, the kind that you can find in any shop. Others, however, operate on a Lithium Ion Polymer battery. This battery is usually just a little smaller than the main body of the earpiece itself.

The battery is often (but not always, as you will read below) small enough to fit inside the earpiece itself, so they tend to only be about an Inch in total length and only a couple of millimetres in diameter (yeah, I know, I mixed my measurements, get off my case already…).  The external batteries I’m talking about below are a little bigger, but even they are typically not much bigger than 2-3 Inches long.

Can a Kenwood Radio be used to Communicate with a Motorola Radio?

To answer your question (that is, after all, why I’m here): It depends entirely on which models you are planning to use. For example, if you had two PMR446 variants that were both on the same band, they ought to work fine (even if one was Kenwood and the other was Motorola).


If two radios are the same basic type and set to the same channel, then I don’t personally see why they wouldn’t work. However, if they aren’t of the same type, then they probably won’t work, it’s that simple. Read more ›

Will I be Able to Hear Bone Conduction Headphones Even if I Wear Earplugs?

Because bone conduction bypasses the ear entirely and directly stimulates the ossicles (which is the scientific name for the tiny bones that reside in your inner ear, as well as the rationale behind comic book hero Daredevil’s athletic prowess), it is entirely possible to stick your ear plugs in and still listen to your ‘Bonephones’.


In some respects, it’s actually preferable. Y’see Nick, using headphones is fine and dandy, until you have to turn the volume all the way up in order to drown out noisy children, busy traffic and/or people shouting into their phones all around you. After that, if you increase the volume to too great a degree, you can expose your ears to sounds that can actually permanently damage your hearing. Read more ›

Ringing within the lugholes, it may be the 1st signs of tinnitus

In recent times, when I was at my younger brother’s birthday party, my Dad made a reference to having tinnitus (fundamentally an occasional-level ringing in the ears) and I told him that I’d made a joke about tinnitus in a recent post (for those concerned, the joke was that it made things sound ‘a bit tinny’ – Not amongst my better japes, I admit, but whatever…). He looked at me like I had just farted in church while I quickly changed the subject. Read more ›

What is the curly tube that Secret Service Agents wear in their ears

You’d consider that the American FBI (being the United states FBI and everything) would have access to an earpiece a bit cooler that just the common ‘curly cable’ job, wouldn’t you?

If forced, I have to state that I often imagine some old fella, like Desmond Llewelyn in the Bond films, (and 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 they use because they work and they work well. Basically, wired models continue to be more reliable than their wireless counterparts. With wireless, you tend to have more interference, as well as having to deal with more limited bandwidth. Essentially, you will need dependable tech when you’re in the field. Lives are at stake in a number of cases.

This straightforward, trusted earpiece might be relied upon to do the job, every time.

Another benefit that wired earpieces have over wireless ones (on this instance, at least) is the fact that a wired set needn’t carry an additional battery. Wireless earpieces would require charging and, as a consequence, would have a somewhat limited operational capability. It just causes a whole lot more headaches for people who, let’s face it, previously have a good bit on their plates to begin with.

According to ‘’

“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’ technology is generally rather common and is used by a number of individuals and organisations beyond the secret service. You are able to even purchase a wireless version, but do not expect the secret service to be involved!

I might argue another point, but this is merely a pet theory with little or no research to back it up. Psychologically speaking, when y’see a secret service agent, you identify them as such without seeing them in any kind of uniform (beyond a suit, shades and an earpiece), the earpiece, then, is a subtle reminder to you, the civilian, that not merely is this not a regular person inside a suit, but additionally the area in which you now end up is being strictly monitored.

With one word to his/her earpiece, the agent in question can probably call down all the other agents in the direct area, also as police, fire brigade and anybody else he/she believes is essential. 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 individual has eyes everywhere and could, potentially, really ruin your week. As I said, it is just a assumption, but I think it makes sense.

The Best Motorola 2-pin earpiece

We spend a lot of time writing about Motorola radios, so we’ve decided to do a series that focuses on the earpieces that connect to them.

Not only do a number of good companies make top-of-the-range two-way radios that are both affordable and reliable, there are also a large array of radio earpieces that range from cheap and cheerful (but nonetheless effective) to the last word in techno badassery (Editor’s Note: not actually a word).

So, kicking off our new 5-part series celebrating two-way radio earpieces, is the GP300 earpiece. lists this thing at a paltry £11.50, but the GP300 is surprisingly high spec for such a cheap device.

Firstly, the GP300 is totally versatile, as it fits into any 2-pin Motorola radio. It may not be the best earpiece ever manufactured, but it will fit with any number of quality Motorola radios. However, I should say that the 300 does require an adaptor block to work with GP320 and GP340 series radios (oh well, you can’t have everything!)

Secondly, the sound quality is excellent; there will be no misunderstandings or botched communications when the GP300 earpiece is in use, that’s for sure. For such a cheap device, it actually reproduces sounds amazingly clearly.

Thirdly, there are the features. These features are a bit thin on the ground when compared with some of the costlier Motorola earpieces, but they still enhance the user experience and add to the overall product.

Want examples? Well, the GP300 is ergonomically designed to fit your ear canal comfortably and is easily able to fit in either the left or the right ear (whichever you happen to favour).

It also has an in-built ‘push to talk’ button, so you’re not dependent on your two-way’s controls in order to send an outgoing signal. There is also has a sprung metal clothing clip that attaches the GP300 earpiece to whatever you happen to be wearing, allowing you to be discreet, as well as to avoid tangling yourself up in cable.

Overall, the GP300 is a fine radio earpiece. Various companies have made better ones and I wouldn’t suggest this one if President Obama asks your firm to guard him on his next family skiing holiday, but for most intent and purposes, the GP300 earpiece gets the job done.

In our next episode, we’ll be taking a look at the GP340 earpiece.

What will the Emotiv headset bring to our daily existence?

The Emotiv headset is known as a pioneering gadget that enables a consumer to work together with the virtual situation by reading his/her ‘thoughts’. Essentially, the headset records the brain’s electrical signals and interprets your thinking-orders into virtual actions.

The Emotiv headphone works by using a tool generally known as an EEG, or electroencephalograph, to monitor the brain waves (and emotional responses) of every gamer, virtually instantaneously translating those readings into digital reactions, movements and movement. Read more ›
