An MKV file contains compressed video and audio streams along with an encoder. A codec or Coder/Decoder is required to play this type of file. MKV aims to be the leading standard for multimedia container formats. It is based on EBML (Extensible Binary Meta Language), a subclass of XML.

Specifically, MKV is a Matroska file – an open source container that houses an unlimited amount of video, audio, and even subtitles data in a single file. Its primary purpose is to create a unifying or universal format for multimedia storage with the benefit of being completely open source.

Matroska is an open standards project. It is totally free of charge to use and the specifications are available to everyone, even to businesses that would be akin to implement it in their products. The source code of the libraries created by the Matroska Development Team is licensed under GNU L-GPL.

Multimedia available in many formats. On the Internet you will find many of these elements embedded in web pages, and today’s web browsers have support for a number of multimedia formats.

The first Internet browsers had support for text only, and even the text support was limited to a single font in a single color, and little or nothing else.

Then came web browsers with support for colors, fonts and text styles, and the support for pictures was added.

The support for sounds, animations and videos is handled in different ways by different browsers. Some elements can be handled inline, some requires a plug-in and some requires an ActiveX control.

Multimedia elements (like sounds or videos) are stored in media files.

The most common way to discover the media type is to look at the file extension.

When a browser sees the file extensions .htm or .html, it will assume that the file is an HTML page. The .xml extension indicates an XML file, and the .css extension indicates a style sheet.

Picture formats are recognized by extensions like .gif and .jpg.

Multimedia elements also have their own file formats with different extensions.

Chosing the use headphones may be a relationship-saving. Using headphones you can listen music or whats movies late at night, without disturbing others by loud noices.

But there is a whole lot more – headphones open up new possibilities. Headsets can let you take your favorite music with you wherever you go.

The use of an appropriate headset  can even provide relief from distracting ambient noise while working or traveling.

Even if it’s just an issue of getting better sound from your home theater receiver, a high-end headphones-pair offers a cheaper alternative to upgrading a speaker system.

Whatever your requirement, it always remain a pre-requisite to choose good quality headsets.

Unfortunately, many treat such a purchase with  a little bit of disregard – possibly because these represent a relatively small expense in comparison to  the rest of their AV gear.

The truth is that if you still want to enjoy the best audio experience from your AV receiver or CD player – it is essential that you have an understanding of what to look for, headphone-specifications, features, design options most suitable for your needs, in particular, the environment in which you will be using your pair, etc.

Cheap headsets might be good enough for listening to your favorite CD while jogging, yet they are unlikely to deliver the same level of acoustic performance you enjoy with a good set of speakers.

Ok, one may argue that it is not right to compare different technologies, in that though these are somehow related, yet speakers and headsets are designed to cater for different needs.

On the other hand, one should be aware that with today’s technology, it is still possible to experience music and movie audio with extraordinary clarity and image detail when using a pair of good quality-headphones combined with Dolby-Headphone technology. Hence, making the right purchase would surely make a big difference in your headphone-listening experience.
