How Do Earpieces Work?

Now then ladies and gentlemen, i’ve one more excellent earpiece article for you to read, i know, you do not have to thank me all, just add a social like to the short article to prove your appreciation.

To put it very simply, your earphone (blogspot.co.uk) includes a piece of plastic that vibrates in accordance to the signals received from the device it’s attached to. The plastic moves due to a metal coil that’s attached to a magnet, which allows the plastic to form the sound waves that pass into your ear.

That’s it, really. It seems easy enough, but I couldn’t have thought of it.

Jezen Thomas at eHow.com provides a more detailed explanation to us, he says that,

“Earphones consist of a speaker cone, an iron coil, a magnet and speaker cables. When earphones are plugged into a music-playing device like a stereo, electricity is sent along the speaker cables. The speaker cables feed this electrical current through the iron coil, which behaves as an electromagnet. The coil then attracts or repels the permanent magnet, depending on the electrical current sent by the music-playing device. This causes the coil to move, which subsequently pushes and pulls the speaker cone. As the speaker cone vibrates as a result of this movement, it creates sonic waves that resonate through the air and are transferred through small bones and membranes inside your ear”.

Of course, there are different types of earphones, but basically, that’s it.

Some earphones, however, do feature additional functions. Noise-canceling headsets, for example, can generate a small field of white noise around the speaker itself, which acts as something of a vacuum and has the effect of disabling outside noise. These headphones are also better for the health of your inner ear than most other types. Sam Costello at About.com writes,

“The noise around us can contribute to cause us to change how we listen to an iPod. If there’s a lot of noise nearby, it’s likely that we’ll turn up the iPod’s volume, thus increasing the chances of hearing loss. To cut down on, or eliminate, ambient noise, use noise-deadening or –cancelling headphones. They’re more expensive, but your ears will thank you”.

Chris Woodford, writing for ‘Explain That Stuff.com’, gives a detailed description of the main differences between earphones and speakers. Despite essentially operating in the same way, there are variations between the two, it seems. He says,

“The biggest difference between loudspeakers and headphones is, of course, size. A loudspeaker needs to set all the air moving in a room so you can hear the sound it’s making, but the speaker in a headphone only has to move the volume of air inside your ear canal. That’s why it can be so much smaller and more discreet”.
If, even after all this tech talk, you’re still interested in seeing what’s going on in your headphones, the Youtube user Cayde Brown has a series of videos called ‘Take Apart’, which will probably be of interest. In one episode, Cayde takes a pair of headphones apart and shows us exactly how they work.

What Features Should I be Looking For if I Want a Bluetooth Headset for Conference Calls?

Without giving too much about this headset short article, but I found it exciting and appropriate to what Im currently doing.

earpieceHi Tina, thanks for the question.

OK, so your basic requirements ought to be simple enough. Firstly, youre going to need great sound quality. Youll need to hear and process important information quickly and without asking the boss to repeat him/herself (unless of course you are the boss, Tina, in which case you dont want your employees making you repeat yourself over and over).

The next feature on our list should be a great microphone, its no good being able to hear everyone clearly if they cant understand a word youre saying! The microphone ought to be able to transmit as cleanly as possible, without picking up too much background noise (e.g. dogs barking etc).

Another factor to consider is comfort, some calls can drag on for hours longer than they were intended to and you need to ensure that you are thinking clearly about what is being said, rather than worrying about the nagging pain on the side of your head! Youll need a headset that is comfortable and easy to wear at all times, something that, ideally, youll forget youre even wearing. If you arent sure how to find that, try on a friends headset for 15 minutes and see how it feels, if it is starting to become uncomfortable, youre probably better off with a different design.

Once youve got these bases covered, youve probably found the right headset for you, but Id read all the reviews you can find before purchasing, just in case! The truth is, that if you want a good quality headset, youre going to need to spend out a little.

A Bluetooth headset is actually a good choice here, because it gives you the freedom to move around. My Dad used to take conference calls with his headset; casually dispensing advice to other attendees whilst tending to his bonsai trees. Sometimes having a little distraction can make all the difference. His thoughts were focussed and his mind was calm. This allowed him to take several conference calls a day and always be at his best. Sitting down for extended periods of time can be more tiring than people think!

Thanks again for the question, Tina, good luck in your quest for the right headset, as well as your career.

The Significance Of Two Way Radio Batteries

For a long time people have been telling me that relations, love and happiness are the crucial things in life…Today I realized that I’m able to take or leave all that as long as I have this earpiece in the world.

Review: Beats Studio by Dr Dre Hi Def Noise Canceling Over Ear Headphones

With very little information on the internet about radio accessory’s, it is very rare when we get a chance to re post, with permission, an article from this industry.

My Beats Studio By Dr. Dre Review…If you are wondering whether the Beats Studio by Dr. Dre – Hi Def Noise Canceling Over Ear Headphones are worth the money, I am hopeful by the end of this article you will have a better idea of the answer.

I do enjoy music and have been known to buy various gadgets before but never in my mind did I think I would spend this much on a pair of high def headphones. In my review, I will cover the features and reasons that helped me open my pocket book. Was it a good choice? Read on to find out…

There is one disclaimer to this review. I am not some major audiophile and don’t understand the science behind the sound. This is not going to be a hard core audio review. I’m just a regular guy that enjoys great sound. So please keep that in mind as you are reading my musings.

Before purchasing the Beats Studio by Dr. Dre I compared them to the Beats by Dr. Dre Solo. I decided on the more expensive Studio because of the better sound quality and greater amount of noise canceling.

Although the size at first may scare you off, the benefit is a larger speaker which provides deeper rich bass

The cables are made my Monster which provide a clear and balanced sound

The ear padding is spacious and comfortable

The cable has built in buttons which lets you take calls on your iPhone as well as other smart phones

The headphones were designed to eliminate external noise for maximum noise cancelling effect

The headphones have a folding design with a nice case

Style. These headphones look great. From the packing to the quality these shout style.
The Beats Studio by Dr. Dre – Hi Def Noise Canceling Over Ear Headphones come in two colors: black and white. The black one’s are sleek and have vibrant red on the sides. The cables that come with the headphones are very sturdy. This is not some flimsy wire that will become defective in a month or two.

Even though the Studio and the Solo fold and fit into a case, I doubt you will be lugging these off to the gym — they just seem to bulky for that. In theory, you could but the ear buds version probably are more practical for carrying around.
Although some reviewers of this product felt differently. One reviewer wrote “for taking the headphones on-the-go and for traveling, the Monster Beats win again in terms of portability. The Monster Beats can be collapsed nicely and comes with a nice protective case to store it in”. Once again, for my purposes I will not be carrying these around but I do see how others might want to bring them everywhere.

Thumbs Up For Beats Studio… See all 3 photos Why I Bought The Beats Studio Headphones…So what sold me on these? It comes down to the sound. I’ve read some of the techno folks negative comments but to my untrained ear the sound is mind blowing — to me worth every penny. The high def sound is rich and deep. One reviewer wrote “the sound quality is awesome while listening to music, even watching regular TV on the treadmill is an enhanced experience.” I agree with these comments and do feel that my overall listening experience has increased because of the rich sound quality.

The noise cancellation is a great feature too. While in the same room as my girlfriend who is watching TV, I am oblivious with my Beats Studio on. In the past, the sound from the TV would bleed into the ear buds I would be wearing. Blocking out the external noise is great and adds to my overall enjoyment. It makes listening to just about anything fun!

One other pleasant surprise about Beats Studio by Dr. Dre – Hi Def Noise Canceling Over Ear Headphones was the integration with my iPhone (and other smart phones). I can take a call while wearing these which is an added benefit.

Is there anything negative to say? Well, yes but it is a minor one, the Beats Studio require 2 AAA batteries. Frankly, for me, this is not a big deal. You can get batteries for nothing now days and so far I haven’t needed to change them. I can see leaving the switch on though and probably needing to replace the batteries sooner than I like but all in all not a big deal. By the way, The Solo’s do not need batteries so if the batteries scare you off — check out the Beats Solo. If you value sound quality and noise canceling, don’t let the need for batteries scare you off.

Overall, I feel my money was well spent on these. Frankly, I fully expected to return them but after using them they are a keeper.

I hope after reading my Beats Studio by Dr. Dre – Hi Def Noise Canceling Over Ear Headphones review you have a better idea of whether these are the headphones for you.

The listening experience alone is enough to make you want to buy a set of Dr. Dre Studio Beats Headphones. Add to this an extremely stylish and clean design, you have a definite winner on your hands.
