Headphones are used for various purposes. While there is no doubt that it is most widely used for listening to music and also to enjoy movies in a private environment, there are many other reasons for which these devices are used. Cancelling noise is very important and it is applicable for different types of activities. Whether it is sports or other applications, these devices are extremely important. They play a big role in helping removing or blocking various types of noises and sounds. They work using a simple technology that is referred to as inverse sound wave. It is very useful while travelling in planes and the inverse sound wave will help prevent noise of the engines. While there are different opinions about these noise blocking headphones, there are certainly some obvious advantages that cannot be overlooked. Let us have a look at them over the next few lines.

Various Uses Of These Headphones

Previously these headphones were used very extensively in the aviation industry because of obvious reasons. Pilots use them even today for cancelling noise emanating from engines. It would also be pertinent to mention here that ground staffs who signal planes also use them not only in civil airlines but also in air forces. It is also very commonly used by shooters to shut down sounds emanating from guns which could affect their concentration.

There are many such brands available in the market today and MSA Sordin is often considered to be one of the most sought after ones. It would be pertinent to have a clear understanding about the various technical features of brands such as Sordin so that customers can get a better picture of the same. These sound cancelling devices are usually connected to a two way portable radios or walkie talkies, which are available in the market. The headphones and other accessories and attachments can also be used and there are many companies which manufacture them.

How It Actually Works On the Ground

The protector headsets come with a noise cancelling microphone which is also referred to as boom microphone. It also has a down load feature and PTT. The down load and PTT directly connect to the two radio systems as mentioned above. This is done with negligible or minimal interference that comes from the outside. Hence whenever there is a need to reduce or totally remove unwanted noise the MSA Sordin device always comes into play. Let us now have a look at some interesting features of these noise reducing headphones.

A Look At Some Useful And Pertinent Features

These devices are very feature rich and offer excellent value for money. The headphones are padded and the soft cushions well and truly provide the right type of comfort. The boom microphones are very useful for communication even in very noisy areas and locations. These devices are also available with or without audio limiters. Quite a few manufacturers allow customization of the audio limiters depending on the specific needs and requirements of customers.

How To Buy The Right Sound Cancelling Earphones

Before buying these devices it is very important to have some understanding about the difference between noise isolating earphones and noise cancellation headphones. What we are talking about in this article is the noise cancellation variants. Hence this point should be made clear before buying them. Audio quality is also an important point to be kept in mind while buying these earphones. You should also make a decision between wireless and wired earphones keeping in mind your specific needs and requirements. Though wireless phones are more user friendly and flexible, they are often more prone to signal interruptions. Price is also a very important consideration when it comes to buying these ear phones.



Going through the right due diligence process is also very important and unless you are sure about the quality, overall features and functionalities you should not go ahead with the purchase. When you buying from reputed online sites, you should look up quite a few brands and choose something that totally meets your specific needs. It is a time consuming process but you should be willing to invest the desired time and effort failing which you could end up choosing the wrong earphones.

What types of spy earpiece are available?

6/14/2015

Assuming you didn’t make your own spy earpiece (we ran an instructional piece on how to build one last year), there are three main types of spy earpiece.



  • Bluetooth spy earpieces


  • Mp3 spy earpieces


  • Wired spy earpieces




The appeal of the spy earpiece is simple (and goes beyond simply having the word ‘spy’ in the title). A spy earpiece is largely invisible to the outside observer, allowing the user to send and receive information in a discreet and covert manner. In recent months, spy earpieces have skyrocketed in popularity. According to this blog entry we sourced,

“We may see in the technology of Bluetooth spy earpiece the future in new methods of quick reception of the audio information from any area - with the help of GSM mobile phones and invisible spy ear pieces. Your partner transfers the information you need to your GSM mobile phone which is further transferred by means of Bluetooth technology to the Bluetooth spy earpiece plugged in your ear. Simultaneously, your partner can hear your replies using invisible microphone”.

The Bluetooth spy earpiece is the most diverse of the three types. Using a Bluetooth spy earpiece, it is possible to relay messages and information between two users. In this fashion, these earpieces are now being used in business presentations and high-pressure working situations, when up-to-the second information is necessary for completion of a task.

The Mp3 spy earpiece is a little different. It can only play back audio information (it has no send/receive functions). However, it still proves to be a popular choice, as this Blogspot confirms,

“The main advantage of mp3 spy earpieces is that you needn't to attract the partner to this process. You can record all-important information in advance on your mp3 device and listen later when it is necessary! Since you are familiar with your own voice and record contents, it will be easier to understand and analyze audio information”.

The final type, the ‘wired’ spy earpiece, is probably the least popular of the three. It’s not difficult to see why; the wire renders the earpiece awkward and conspicuous. Despite wired technology still having a (general) advantage over wireless in terms of transmission speed and reliability, spy earpieces are one technological avenue that needs to attract as little attention as possible to itself (the operative word being ‘spy’) and a wired earpiece just doesn’t camouflage as well as a wireless one.



On this, the blog says,

“It is a bit (of an) out-of-date approach to the problem. Usual wired earpiece does not differ from Bluetooth one except that the micro earpiece is communicated to the GSM mobile phone by wire, often inconvenient in use”.

 The Bluetooth spy earpiece is definitely the best choice in terms of versatility.

Lost Copy Of Shakespeare's First Folio Discovered

6/4/2015

A lost copy of Shakespeare's First Folio has been discovered in Northern France.

The First Folio is the name commonly given to the 1623 collection entitled Mr. William Shakespeares Comedies, Histories Tragedies. The book contains 36 plays, a great many of which had never been published prior to 1623, which makes The First Folio an extremely important document, as it represents the only original source for all subsequent printings/performances of many of Shakespeare's works, such as The Tempest, The Comedy of Errors, The Taming of The Shrew, Twelfth Night and Julius Caesar.

Counting this new addition, there are only 233 first edition copies of this book left in the world, and each have small textual variations that shed new light on Shakespeare's writing style, creative process and (possibly) his personal life.

The book was discovered in the public library of Saint-Omer, a small town near Calais. Prior to this, it had been held in a Jesuit college in the town. It was moved to the library following The French Revolution, which ended in 1799.

In addition to being a major literary event in its own right, the discovery of the book has sparked new debates as to The Bard's religious affiliation.

For over 150 years, some scholars have suggested that Shakespeare had links to secret Catholic sects that were outlawed (and severely punished) in the 16th and early 17th centuries.

Elizabethan England was officially a Protestant country and Catholics were brutally suppressed under this regime. Proponents of this theory cite examples in Shakespeare's writing (in particular King Richard The Second) and the presence of the mysterious William Shakeshafte at the home (and later in the last will and testament) of Alexander Hoghton, a known underground Catholic.

This previously unknown First Folio is thought to have made its way to France in the possession of Edward Scarisbrick, a well-known English Catholic who is believed to have studied at Saint-Omer in the 1630's. Scarisbrick was known to go by the name Nevill – and this book is inscribed with the same name.

The Jesuit College that originally owned the book sheltered Catholic exiles and also trained Englishmen who wished to become priests. Today, the institution still exists, although it has been relocated to Lancashire.

Other works of Shakespeare have also been discovered in the Jesuit College at Douai, Northern France.

Of course, this evidence alone merely proves that English exiles enjoyed reading Shakespeare. As Dr. Martin Wiggins, a senior fellow at the Shakespeare Institute in Stratford-Upon-Avon told The Independent, “He was admired and studied by English Catholics. We already knew that. Now we have more evidence. That doesn't mean that Shakespeare was himself a Catholic sympathiser,”

The book will be put on display in Saint-Omer as part of an exhibition of old English texts, something that is expected to draw tourism from interested parties.

Dr. Wiggins has also suggested that the copy, which has been annotated with stage directions by an unknown party, probably represents the earliest known school production of Shakespeare.
