What are Earbuds?

When we found this article we were so pleased, having looked for over a year for this, finding it on this website was an thrilling day for yours truly.

Earbuds are headphones, typically made out of a hard plastic material, that fit inside the ear, just outside of the ear canal. These aren’t the same thing as ear canal headphones, which have a rubber tip and seal within a listener’s ear canal.

Several portable music devices, like mp3s and Personal Digital Assistants (PDAs), come with earbuds when the device is purchased. Earbuds are a less expensive alternative to ear canal headphones or other listening devices. Consumers tend to purchase earbuds for their convenience, as they are easier to carry around than other headphones because of their small size.

This style of headphone also tends to be more inexpensive than other kinds, like ear canal headphones, circumaural headphones that fit outside the ears, or the supra-aural headphones that have pads that are placed on top of the ears, rather than around or inside them. Circumaural headphones are typically used in recording studios and supra-aural headphones can still be purchased at some stores, though these kinds of devices have given way to headphones that fit within the ear.

Because of the design of earbuds, there can be a few drawbacks to owning them as opposed to owning another style of headphone. First, the rigid design of earbuds can sometimes make it difficult for them to fit comfortably inside a listener’s ear. If they’re too large or too small, they can either slip out of the ear or won’t fit inside it at all. Another problem reported by consumers is that because earbuds don’t seal the ear canal, the sound quality is muddled through other ambient noises.

Essentially, most earbuds work the same as other headphones and the set-up is relatively simple. Wires move up from the electronic device that is putting out sound, such as an mp3 player. These wires connect to a voice coil. The coil is attached to a cone, which is flexible and plastic. A magnet is attached to the back of the earbuds. When sound passes up through the wires and to the magnet, the voice coil becomes electromagnetic and moves up and down with the sound. The cone then pushes the sound out through the earbud and into the listener’s ear.

When listening to earbuds or any other type of headphones, physicians recommend to keep the volume at a reasonable level, as research had proven that prolonged exposure to high noise levels can lead to permanent hearing loss. Prolonged listening to loud noises, including music, puts unnecessary stress on the hairs in the cochlea. This causes permanent damage to the hairs and can eventually lead to hearing loss.

Here’s a Brief History of Headphones

So to resume my run of posts on this blog, I have planned to share one of my favourite posts this week. I used to be cautious to include it to a site because I really did not wish to offend the original writer, but I trust he/she is glad that I loved reading their article and wanted to share it with my readers.

During the past century, human ears have enjoyed less freedom than ever before, but more music, thanks to the invention of headphones. In 1910, a Nathaniel Baldwin invented headphones in the kitchen of his Utah home, forever subjecting our ears to the shackles of small speakers.

Aside from allowing you to furtively listen to the latest Carly Rae Jepsen single, headphones enable people to privately and individually interact with media, even when in a noisy room or a crowded subway. Headphones are also crucial tools used for recording music, and producing films, TV and radio programming.

Here is a timeline of how we’ve gone from Baldwin’s “Baldy Phones” to Apple’s earbuds EarPods and “Beats by Dre.”

1910: Nathaniel Baldwin Invents the First Headphones

The legend states that Lt. Comdr. A. J. Hepburn of the U.S. Navy received for prototype for a pair of telephones fashioned into a headset, along with a letter from Nathaniel Baldwin written with purple ink on blue and pink paper. After initially disregarding the message, Hepburn tested the device and found that it worked surprisingly well to transmit sound.

The Navy began to ask for more headphones from Baldwin, who could only accept orders of 10 at a time because he was producing them in his kitchen.

If it’s not evident from his choice of stationery and writing utensil, Baldwin was an interesting fellow. He was a fundamentalist Mormon who studied at Brigham Young Academy (later renamed Brigham Young University), and eventually earned an electrical engineering degree from Stanford.

He returned to BYU as a professor but was fired for speaking out in favor of polygamy, a practice which the Mormon Church renounced in 1890. (Though he endorsed polygamy, he had only one wife.)

Original Koss SP3 Headphones1958: John C. Koss Introduces SP3 Stereophones, Made For Music

Until this point, people used headphones almost exclusively for radio communication.

John Koss was born and raised in Wisconsin. He got married in 1952, at which time he started a business using a cash wedding gift with which him and his bride were supposed to buy a sofa, according to the Wisconsin Historical Society.

While introducing a portable phonograph he wanted to rent to patients in Milwaukee hospitals, he revealed the original Koss SP3 Stereophones. Initially intended to be a sidebar, the headphones proved revolutionary because their sound quality made them optimal for listening to music. The Koss Corporation, located in Milwaukee, is still making headphones today.

1979: Sony Releases ‘Walkman,’ Headphones Go on a Diet

Before portable music players, headphones tended to be big. Baldwin’s original set weighed upwards of a pound.

Koss’ stereophones were circumaural, meaning the earpads would literally engulf your ears. It made sense at the time. “Audiophiles” could listen to the latest Beatles, Pink Floyd and Led Zeppelin albums in the comfort of their homes, and the bulbus design of their headphones helped to block outside noise.

With the help of the Sony “Walkman,” recorded music soon liberated itself from the home stereo, creating a need for more portable headphones. Conveniently, a lightweight set of MDR-3L2 headphones was included with the portable cassette player. As opposed to Koss’ circumaural headphones, Sony’s were supra-aural, meaning the earpads pressed against the ears.

 

 

1989: Dr. Amar Bose Introduces the First Noise-Reducing Headset

On a flight home from Zurich in 1978, Dr. Amar Bose tried an early set of electronic headphones that were newly onboard for passenger entertainment — but he could barely hear anything with the overwhelming cabin noise. He returned to Boston and set up a research program at Bose Corporation (which he founded in 1964), to investigate how ambient noise could be reduced with active noise cancellation. The Noise Reduction Technology Group (NRTG) grew out of that program, and in 1989, the company introduced the first noise-reduction headset, designed for the aviation industry.

2001: Apple iPod Includes Earbuds, Which Now Total 600 Million

The trend towards smaller and more portable headphones eventually led to earbuds and in-earphones, which only differ in the degree to which they wedge into the ear canal.

In 2001, Apple introduced the iPod to the world. The iPod, and later iPhone and iPad, comes with a now-iconic set of basic white earbuds. A decade later, iPod sales have topped 300 million. Begin to do the math, totaling sales of iPods, iPhones and iPads, and you begin to realize there are an astronomical number of Apple earbuds in circulation.

During the announcement of a long-awaited upgrade the company’s stock headset at the iPhone 5 unveiling on Sept. 12, Apple said that it had shipped 600 million sets of the first generation of earbuds — that’s roughly one for every 12 people on the planet. Regardless of your opinion on the quality of the product, those earbuds get around.

2008: Beats by Dr. Dre Hits the Market

Hip hop artist and producer Dr. Dre teamed up with Interscope Chairman Jimmy Iovine to launch Beats by Dr. Dre, helping to solidifying headphones as a fashion statement. The brand has recruited celebrities, including Will.i.am, Justin Bieber, Lady Gaga and Lebron James, to endorse the products. Today, Beats by Dr. Dre has 63% market share in U.S. for headphones priced over $100.

2011: Sennheiser Sells $40,000 Orpheus Headphones, World’s Most Expensive

At an audio show in Seoul, South Korea, the German headphone company Sennheiser unveiled the world’s most expensive headphones. The company released 300 sets of the Orpheus headphones, which were priced at 30,000 Euros, or roughly $41,000 a piece.

If you’re still on the fence about making that big of an investment, try them out with the following video.

2012: Apple Redefines Earbuds with the EarPods

The launch of the iPhone 5 ushered in a new era of headphone design — the EarPod. The periscope-like headphones are designed to direct sound right into the ear, and they hold up pretty well.


Headphones have come a long way in the past 100 years, revolutionizing the way we consume media and the way we communicate. In addition to sets that transmit with extremely high fidelity, other notable advancements include wireless headphones, Bluetooth headsets and headsets that include a microphone which can be connected to telephones or computers.

As portable media consumption continues to rise with smartphones and tablets, the need for headphones will be greater than ever.

What Is Covert Surveillance?

Thanks for reading my blog, here is a piece of writing i really loved reading. With their consent i’m able to repost it. I write plenty of my own posts, but sporadically post other content i think are fascinating, thankyou for reading.

Covert surveillance occurs when someone or something is being observed without knowledge. People who are under surveillance are most often under suspicion. Locations and buildings are primarily observed because of suspicious activity or to obtain information about a suspect.

covert surveillance Covert surveillance is generally performed by government agencies, private investigators or business owners. Intelligence organizations such as the Central Intelligence Agency (CIA) of the United States and the United Kingdom’s Secret Intelligence Service, also called MI6, participate in surveillance to obtain information for national security interests such as counter terrorism. Law enforcement agencies such as the United States’ Federal Bureau of Investigation (FBI) or the International Criminal Police Organization (INTERPOL) also perform surveillance. They concentrate on observing suspected criminals.

Private investigators perform covert surveillance for a variety of reasons. Husbands and wives hire private investigators to prove or disprove suspected infidelity. Businesses hire private investigators to observe employees who are suspected of fraudulent activities or former employees that may be breaking confidentiality agreements. Insurance companies are notorious for using private investigators to put claimants under surveillance to ensure they are not submitting a fraudulent claim.

Many business owners participate in covert surveillance of their employees and customers. Observing employees while they are working gives business owners valuable information, such as employee production and employee theft. Covertly observing customers can aid in marketing and research efforts and most importantly account for loss due to theft in retail businesses. Retail businesses can also use information obtained through covert surveillance to prosecute shoplifters.

A surveillance operation may be carried out in a number of ways. Agency employees and private investigators may choose to observe a subject without the aid of sophisticated technology, using things such as binoculars and cameras. However, in an age of modern technological conveniences, it is safer, cheaper and more convenient to use surveillance equipment.

Closed circuit television systems (CCTV) are one of the most popular ways to carry out covert surveillance. Cameras come in all sizes and can be placed inconspicuously almost anywhere. In order to obtain audio, wire taps can be placed on phones or audio surveillance equipment may be hidden in a suspect’s office, home or vehicle. Other ways to perform covert surveillance include aerial surveillance and the use of global positioning systems (GPS). A GPS placed on a person or moving vehicle can be tracked to monitor movement to specific locations. Similarly, aerial surveillance carried out by national governments can track objects on the ground.

 

Get a Gp 340 earpiece for the best cost

We ended the last piece by saying that you should not use the featured earpiece to protect the life of US president. Yet, we will start this piece by saying that, if you’re trying to guard President Obama over the next few months, then you’re getting closer to the right view with this earpiece.

The Motorola multi pin covert earpiece is really a significant bit of comms. This earpiece comes attached to one of the curly receivers, the type you’ve seen Agent Smith wearing in The Matrix films. The Motorola multi pin earpiece is a tool designed for use with the GP340 range of walkie talkie devices. Continue reading »

If you use the new Motorola DP2400 two way radios at work, then you need to look at these earpieces

Well, dear readers, here it really is, the last of the five-part series on two way radio earpieces.

We have thrown completely random pop-culture references at you (all from ‘Wacky Races’ to 007 himself) and we’ve (optimistically) had a few laughs amongst all of the dry facts and information. When you’ve read all of these things thus far, then cheers, we appreciate your time.

OK, so the final item on our list is the Motorola DP2400 earpiece, which is the most costly earpiece we’ve viewed so far, albeit by only £2. The Motorola dp2400 earpiece, then, (for those among you who haven’t been keeping count) might be purchased from Earpieceonline for £29.75. Continue reading »

What’s the Best Bluetooth Headset

OK, To have the ‘flaking’ part of the answer out of our way good and early, I have to say that it depends completely on what you would like from a headphone. There is not much point spending out on an all-singing, all-dancing tremendous-headphones if all you want is a basic model, but, with the same token, great quality does not come cheap in the planet of electronics.

However, that’s not what you wanted to hear, is it?

OK, so, here are some of our best Bluetooth headphones that I’ve looked at so far… Continue reading »

What Does a Live Performer Hear in their Earpiece Whilst Performing?

(Asked by Ahmed from Nottingham)

I’ve been in a few bands myself, but none of them ever got big enough to warrant anything as extravagant as an earpiece, so I can’t answer your question from personal experience.

I do remember doing one gig where the guy in charge of the mix (who’d made his name mixing for a very famous David Coverdale-fronted 80’s rock band) flat-out refused to let us do a soundcheck, assuming that all the bands featured on the show, no matter what style of music they played, could all be mixed the same way. Maybe that’s the reason that particular David Coverdale-fronted 80’s rock band never made it into my record collection…But, whatever, I digress… Continue reading »

How does bone conduction work?

Bone conduction headphones (commonly referred to as ‘Bonephones’) are actually really clever. In order to best explain how they work, I’ll need to take you on a journey into the Human ear…

No, not literally. That would be disgusting.

OK, so you know how sound travels through the air? Surely you must have done that science experiment at school where you hear sound disappearing into an airless vacuum? Yup, it’s just like that. Continue reading »

The PD782, PD785 & PD702 Hytera Radios are starting to take some of the digital market from Motorola, what makes them so good?

The PD782, PD785 and PD702 Hytera radios are affordable, as well as being easy to use and providing high quality audio. This is a good combination when it comes to two-way radios, a technology that, by definition, needs to be durable, easily replaceable and effortlessly useable in case of emergency.

The parent company, Hytera, have been operating since 1993 and in that time they have developed a strong reputation as an industry leader. In short, they are in the process of cultivating a trusted international brand. Hytera are an emerging brand with a considerable track record for producing quality technologyv at premium prices.

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. Continue reading »

Why Do FBI Agents Always Touch Their Ears

When you see American FBI agents on Television or in films, maybe you noticed that they are consistently touching their ears? Well, at least one of our readers did and asked me to find out why.

By the ‘Matrix’ movies, Agent Smith and co touched their ears so as to better mimic the behaviour of genuine FBI agents. Consequently it is visibly a defining trait of secret service agents, at least in United states. It’s clearly something they have been doing for quite a while now. Although, the ‘Agents’ also did it to better receive signals on the machines who ran the Matrix program itself…

Inside the real world (assuming, naturally, that this IS the real world hmmm….), the reason that FBI agents touch their ears is not that different. Forrest Wickham, of www.slate.com, has the advice:

Are those earpieces uncomfortable? No, it’s just so they can hear better. Pushing in an earpiece makes for a tighter seal, which could mean the difference between hearing or missing a Secret Service codename or another agent’s message about the president’s position while standing in a noisy room. While earpieces are not uncomfortable, they do sometimes come loose, requiring readjustment.

There you have it, a rather embarrassingly lo-tech answer, FBI guys push their radio earpieces into their ears as that makes the instructions come through louder and clearer. Like a fanatical ‘Spinal Tap’ fan, I cannot help but echo the bemused query of Marti DiBergi and ask “why just make the earpieces louder?” but that’s obviously an issue for another time.

Back to you, Mr. Wickham:

“Earpieces aren’t the only communication devices the Secret Service uses, and not all earpieces have the same design. Some devices, for example, look like iPod ear buds. The one-ear headphone often shown in the movies is standard and comes with a curly wire that runs down under their shirt to a hidden microphone worn in different locations depending on the circumstances of the assignment. One standard spot is just under the shirt sleeve. (That explains why agents are always lifting their wrists to their mouths.) Earpieces also come in different colors, and some agents choose a device that matches their skin or hair”.

So they don’t take action to appear sinister, or to receive instructions in the engine world that secretly runs all our lives. They do it as, well, their equipment is a little bit crappy, evidently.

However, I suppose that if you were attempting to hear very specific, essential information in a busy and loud environment, then any earpiece you used could be sternly challenged. It is hard to listen to everything over the sound of large crowds as well.

Mr. Wickham also provides a bonus explanation. At the end of his article post, Wickham tells us why the secret service guys forever seem to be wearing shades.

“Why are Secret Service agents always wearing sunglasses? To keep the sun out of their eyes. While the Service has often cultivated a certain mystique, preferring to remain “cloaked in silence and mystery,” spokesmen insist they wear shades merely for their traditional purpose, and not, say, to keep would-be assassins from knowing which way they’re looking. The Secret Service has no set uniform, but agents say that wearing sunglasses on a sunny day helps them to scan a crowd for suspicious behavior”.

Sounds adequate to me.

 

What are the Practicable Purposes of the Emotiv Earphones?

The Emotiv headset may be a revolutionary device that allows a consumer to cooperate with the virtual location by reading his/her ‘thoughts’. Fundamentally, the headset records the brain’s electronic signals and interprets your thinking-instructions into virtual actions.

The Emotiv earphone works by using a tool known as an EEG, or electroencephalograph, to observe the brain waves (and emotional responses) of every gamer, nearly instantaneously translating those readings into virtual reactions, actions and responses. Continue reading »

Earpieces, in the modern world, why it’s beneficial to purchase a superb set

As a comprehensive and utter song nut (some might say ‘nerd’) earphones are essential to me. The particular sounds that we listen to from our earpieces are distinctive to every enthusiast of music. Some sort of a bottomless, bass heavy sound from their earpieces, while others wish their earpieces developed for softer, more coherent, tones.

I lately ruined my very own set of headphone, I was making my way back home on a long train journey and my trusty headsets just died. Miserable. As stuff go, they are way more personal than most transportable belongings. earphones are the devices that provde the enjoyment of that song you adore. Continue reading »

Get a CP040 earpiece for the best cost

Last time, we checked out an earpiece expressly designed to work with the Motorola multi pin 2 way radio series. This time, we will be looking at the Motorola cp040 earpiece, an affordable and adaptable little doohickey that is amazingly thrilling, but also does little to damage one’s deposit account.

The CP040 earpiece is a lot like the Motorola gp300 earpiece. It is little, smart and inexpensive, however it also is pretty good value for money. EarpieceOnline lists this earpiece for about £11.50, but it’s a pretty good deal for the cost.

We’ll be candid, everything is pretty essential on this model, but the device performs its operation well and definitely won’t let anybody down.

The noise quality of the Motorola cp040 earpiece is excellent indeed and the PTT ‘push to talk’ utility is well-located and simple to use. As usual, the Motorola cp040 earpiece has a sprung clothing clip that attaches simply to most items of gear (you might find it a challenge if you’re planning on using it whilst dressed as a giant Sumo wrestler and competing on ‘Takeshi’s Castle’, but besides that…).

As with the gp300 series, because it only features a 2-pin plug, an adaptor block will be necessary for use with the GP320 and GP340 series of 2 way radios.

The ergonomic D-shaped earpiece itself is comfortable to wear and generally discreet. It can be easily used in either the left or right ear, depending on one’s own preference. The Motorola cp040 earpiece fits most ear dimensions, so unless you happen to be Prince Charles or Martin Clunes (Editor’s Note: or my Uncle Alan), you shouldn’t have too many comfort issues, if any.

There’s no Kevlar cable on this one, however but it positively isn’t the best model around. Still, this isn’t to say the Cp040 2-pin is really a inferior earpiece, not at all. It just isn’t the finest.

In general, the Motorola cp040 earpiece is practical, instead of flamboyant. It does its job with no frills (but additionally no temper tantrums). This is really a excellent, reliable product from a company that excels at producing such products. It also provides enormous value for money, too.

Next episode: We have checked out some of the mid level products available, now its time to find what else is about. We’re disscussing James Bond stuff! (Well, you know, But if you need to understand more about this earpieces see earpieceonline

If you work with DP3400 two way radios at work, then you need to look at these earpieces

Last time we mentioned that James Bond might use the earpiece we’re about to describe if he were helping a mate to guard a nightclub. We realize that it’s a bizarre situation to find yourself in, but its probably happened a couple of times in some early Ian Fleming drafts…(Editor’s Note: Wow. That’s quite a tangent. Well done).

The DP3400 earpiece looks good, works well and doesn’t cost a lot of money. You really can’t fault it on its merits.

The DP3400 earpiece features an HQ PTT earpiece that provides incredible clarity and depth of sound. Any instruction, even if a laryngitis-stricken Muttley delivers it to you from a library somewhere, will be clear, clean and crisp to the ear.

But that’s not all, not by a long shot. The transparent tube is almost invisible, designed specifically for secrecy and discretion; it even comes with an extra earbud.

It even has (and we swear we’re not making this up) a hidden micro-speaker located at the base of the centre of the PTT switch.

Earpieceonline lists this product at £27.50, but that strikes us a genuine bargain. This earpiece is covert, brilliantly made and extremely high quality. It is also durable and hard wearing. Of most of the devices we have looked at to date, this DP3400 earpiece is unquestionably the coolest looking. By way of performance, it’s also the best one we have seen so far.

The DP3400 earpiece is compatible with LOADS of Motorola (and Motorola TRBO radios) including (but by no means limited to): DP, DGP, XPR and XiR Series. XiR-P8200, XiR-P8208, XiR-P8260, XiR-P8268, XPR6300, XPR6350, XPR6500, XPR6550, DGP-4150, DGPTM 4150+, DGPTM 6150, DGPTM 6150+, DP-3400, DP-3401, DP-3600 and DP-3601.

Overall, this is a fine device. The DP3400 is an excellent earpiece, available at a pretty competitive price, with a cool, functional design and a lot going for it. No, this isn’t the same model that the CIA use when guarding Mr. Obama, but it isn’t a hundred million miles removed, either. This earpiece will do a good job, whilst at the same time not breaking the bank.

Next episode, we will bid you a tearful goodbye as we embark on the last in our series of two-way radio earpieces. We’ll be looking at the most expensive item on this list and making some more dumb jokes, stick around.
