“Topic of this month, the audio system”(Earphones)

Vonia AWEdible EMP-900 Earset (Earset)
  
      
Commuting by subway these days is look before you will see the appearance of the other passengers. Needless to say the young and old people even wear ear earphones use a smartphone or other Tablet PC and will find it easier When you are on the subway you might not know who is wearing headphones. But in the subway about 20-30% are wearing them.
If you go anywhere with a lot of people and crowded streets, like in the Gangnam or Myeongdong and Chungmuro area, you can see that  most people are using earphones.
These earphones are a necessity of life for many people living in the modern world and are a new technology. Developing state-of-the-art technology to diversify the earphones is seen in the design of bone conduction headphones.

You can use it when you listen to language and sports, and many types of special purposes for the headphones are being introduced. This earphone market trend in Korea, and worldwide, is on the rise. Many companies in this market are trying to find their niche.
People have become interested in earphones within recent years. Last year there was a review of the development of the AK100 MQS system. The results were that different types of headphones will emerge to compete with other speaker systems.  
However, there are several kinds of earphones that have come and gone. The problem is that the sound quality and playback gradually decreases. Different factors also contribute to how you become accustomed to your headphones like ease of use, body movement during listening and how long they are used.
Earphone products today focus on the exterior design, sound quality, portability and storage convenience. These qualities are used to help people determine what kind of headphones they want and the price they are willing to pay.
Many new state of the art products have emerged in earphone technology. Newer products are designed to provide more lifestyle products that meet needs while providing essential sound quality.
Products can be easily attached to a small speaker system, but the most portable way to listen to music is to wear earphones. SOLiD has a lot of people interested in the small earphones for listening to music. The demand for the high performance products will only increase.
The CD sound quality upgraded to the already existing 16-bit/44.1kHz CD player sound generalized by a 24-bit 192Khz sound appeared and a high-performance Smartphone emergence becomes more sophisticated.
Amplifiers and speaker systems are relative to each other because the product is shown through the playback quality. Most people think of small music speakers that can be used instead of using earphones.

AWEdible EMP-900 Audition
  

Commentators chance (weeks), but they do not sell yet in market, Vonia developed  that product model Earset: AWEdible EMP-900 sound products was told. A famous foreign headphone(US$200.00 MSRP) manufacturing company S's(in Germany Company) rotary volume control on the design of the earphones and was watching of this product would have been interested in watching it.
Bone conduction headphones have been used for personal use until now. The company was founded in 1979 and mainly produced the company's high quality for listening to music. Earphones integrated into many different state of the art products are being developed.
There has not been technology produced domestically and it’s a product foreign commentators have not heard of. Product development engineers have even more interested are the review of a Music critic below. By looking at the product data, the low frequency transient suppression Vibe ramble and ramble, mids and treble transient dynamic band consist of a 2-way type. You can feel the bass and the band has the ability to maximize the near 100Hz SPL when the vibrations are transmitted through the impact sound source.
The transient dynamics of the high band ramble is not considered as regular earphones have a resolution for crystal-clear sound. When watching commentators for the first time, they felt a strong sense for the high band. For a long time, I have found that the crystal-clear sound appealing.
The performance of earphones compared to the first models as a music source has come a long way. They clearly have a different sense of sounds. The one clear thing is the sound quality. The bass low and high band showed a difference in sounds. Astell &Kern's AK100 MQS system comparisons in listening were interesting. Note to people who have used this reviewer, the AK100 MQS systems, audio transcription system developed such as a dedicated headphone amplifiers Music Shower MS15A model and 24-bit Aprilmusic's/192KHz CD player and DA converter system model Stello CDA200.
Earphone products of today depend on the exterior design, sound quality, portability and storage convenience and may be used to select a price many in lots of more products to meet their own mind. In particular, many kinds of new products have emerged in the development of state-of-the-art technology are designed for sound quality for people with active and on the go lifestyles.
Product that can be easily attached to small speaker systems in the living room, but the most portable products those that can be used with headphones. SOLiD as a lot of people interested in the small earphones listening to music and the demand for high performance products will increase.
The CD sound quality was upgraded to the already existing 16-bit / 44.1kHz CD player and the sound was generalized by a 24-bit 192Khz sound. The high-performance Smartphone has led to an emergence of a more sophisticated headphone.
This technology has been produced domestically and is interested to hear about what foreign companies have not been able to do. The high-end speaker systems have been developed the product development engineers and the Music critic comments below.
By looking at the product of this data, the low frequency transient suppression Vibe ramble and ramble, mids and treble transient dynamic band consists of a 2-way type. You can feel the bass, the band has the ability to maximize near 100Hz SPL when the vibrations are transmitted through an impact sound source.
The transient dynamics of the high band ramble is not considered as regular earphones have a resolution for crystal-clear sound. When using it for the first time the high band and crystal clear soon was appealing.
The performance of earphones compared to the first models of digital players as a music source has come a long way. They clearly have a different sense of sounds. The one clear thing is the sound quality.

The bass low and high band showed a difference in sounds. Astell &Kern's AK100 MQS system comparisons in listening were interesting. Note to people who have used this reviewer, the AK100 MQS systems, audio transcription system developed such as a dedicated headphone amplifiers Music Shower MS15A model and 24-bit Aprilmusic's / 192KHz CD player and DA converter system model Stello CDA200.
The 24-bit soft 16-bit/44.1kHz sound 192Khz, DSD, SACD came from a variety of sources, including Audio consumer market, Female vocalist Rebecca Pigeon's Spanish Harlem Classic and looked into a variety of genres, including jazz and pop.
Vonia's earphones clearly represented the female vocalist Rebecca Pigeon's voice from the singer's pronunciation. The EMP-900 products sound quality was very accurate.
The popular song “Hotel California” by the Eagle's was very clear with vocal pronunciation and easy to understand. Angel of Harlem called Various Artists unique vocal voice pronunciation perfect to emphasize the Bone Conduction Transducer that the development of the technology of this product.
The way the Vonia Corporation uses the high efficiency and miniaturization of high-tech Transducer (High Tech) is a wonderful technology. I tested instrument sounds this time.
Recordings of Janos Starker's Bach cello 176.4KHz, Suite For Cello Solo N01 in 1007 24-bit/G Prelude BWM 1007 and Haydn's Quartet String Quality in D Op 76 N0-5F final Presto,
When you listen to classical music for long periods of time is the first time you know with these headphones. The speaker systems have good performance over time, but the earphones get it the first time.  
Violin or Piano sounds rather than the sound of a stringed instrument were very accurate instrument sounds that helped us. When you hear the stringed instruments, the softness of sounds is carried out with a more precise touch and sound.
This time, the clear male vocals of Michale Hoppe called Requim of the Sanctus (holy) 16-bit 48khz recording was very clear. You could hear just the music playing with much vibrancy. Commentators have held concerts in mid-December last year in Mokpo and I was in a high-speed bus for about 4 hours and felt no fatigue with headphones on.
Dynamic playback quality is not only clearly transparent, but clean bright and beautiful sound playback and high sound quality. Most young people are accustomed to the band's dynamic sound quality of music on the headphones.  
If you plugged your ears with headphones for a few minutes you would fail to hear good music. But with these headphones you did not get that sense.
Some people believe that only good sounds can be heard through an audio system.  Asa's model AWEdible EMP-900 products provide luxurious quality. But anyone interested in the quality of sound would find this product a collision of products. The design features need to be looked at in more detail.
At first look, the exterior of the earphone structure is taken into the mold rather than a hard surface. An anodized aluminum cutting is used to avoid scratching the surface.
Bone conduction headphones were not available for personal use until now. The Vonia Corporation was founded in 1979 but mainly produced for commercial use. The company's high quality performance can be seen in their earphones and is in the works for development in a variety of platforms.
You hear the voice of the singer as it was meant to be heard.  Eric Clapton's, “Tears in Heaven” and Nora Jones song "Don't know why" provided very accurate voice sounds. This time, the Japanese audio critic (三浦 孝 仁)Takahito Miura, listened to the summertime jazz instrumental recording of song selection and configuration DSD recording. Live SACD of the original sound with the earphones produced good sound.
When there are many different elements of sounds being converged, it is hard to tell the difference between and single out. When listening to the classic 24-bit and 1812 Overture OP49 Kiev Symphony Orch Chorus and Childern Erich Kunzel & Cincinnati Pops Orchestra 176.4khz recording, the sound quality of the earphones helped us distinguish the sound quality of instruments.

EMP-900's Vonia dual balance Earset

        
According to the company's description, this product features a dual-balanced unit created to mount one step after BCT. The tweeter mounted plays realistic and powerful 3D sound and provides a fast-paced -realistic feel. This vibration units have a variety of unique pitches Experiments have several sources to see this.
Clearly there is more of a difference than I thought. Earset performance of hi-fi sound from the earphones listening training are important. Let's look a little more at the specific features of this product.
This company leads the world's only technology, with state-of-the-art and top notch technology and awareness securing the world's first global telecom equipment market and in domestic businesses.
Bone Conduction technology of miniaturization, high efficiency and the development of special purpose earphones were previously covered. The development of high efficiency and miniaturization of the oscillator is a high-tech technology of this product.
The Bone conduction headset has many high efficiency applications such as headphones, bone conduction microphone, bone conduction communication equipment, and on motorcycles. Military and police helmets and formed integral telephones, multi-channel headphones, bone conduction vibrators are other examples of the miniaturization of this high tech product. .
The 2013 market has made the emergence of new technology products for earphones.
In other words, the company strengthens its technology development core competencies, and future-oriented knowledge management. It is aiming at the world market to expand new business items to be more efficient and ensure market supply of the bone vibrator control.

Various designs and high-performance earphones emerge.

        
CES 2013 opened as the world's largest consumer electronics exhibition in Las Vegas in January. I wouldn’t be surprised if this headset was the winner of the Innovation Award.
Every year this exhibition has included many varieties of state-of-the-art headphones (earphones included). This year there were more than a dozen headphones at the 2013 exhibition.
A growing number of new products have emerged. One of these is a headphone amplifier system. It has joined the existing high-end systems. Many manufacturing facilities equipped with state-of-the-art technology are teaming up with makers in the development of developing a number of products
What is the reason? To define its own. A new product has emerged that led to increased demand for the product, Insertion Type (In-Ear) phone. This is a new product that has emerged.
This product for earphone can accommodate a growing manufacturer to develop in a new design that provides high-performance products. This kind of earphone is a rapidly growing trend people are demanding.  
The age of the earphone consumer has reversed as in previous years. In the past the youth have been regarded as the earphone market. Now the adult consumer, between 40-60, have become the market to target headphones that are comfortable and become state-of-the-art equipment.
Essential information and communication mediums have emerged as Smartphones and compact design of various digital music player products. Earphones are now and indispensable item. This commodity is what is driving new products to be developed.
Low cost earphones will over stimulate the ear if you listen to music for a long period of time. This large amount of volume for a long time can cause hearing loss. We realistically do not know the limits of earphone products.  
Famous foreign manufacturers take advantage of their famous brand earphone to developed new products that will be noticed.
