Why get caught up in wires? Go to your audio wirelessly

Tangles, knots and hooks are the things all too familiar to listeners who use headphones, or on the road or at home. And if you have not taken into cables, I wonder "how did you do to avoid them?"

Access to music, implemented at any time and anywhere, and has expanded at a tremendous speed in recent years. Technologically, the music industry and its affiliated companies are aware of their very "up to speed target market 'and developed in amost technically expert machine mobilized.

Wireless Headphone Ipod

Behind every street corner, a small shop in the corner and middle of the swarm of public transport, the iPod revolution flourished; wires are everywhere. This revolution of its own momentum, it is almost impossible not to take advantage of the innovations currently booming. But, before entering the drum beats the current iPod and headphones, check out the options: what to do with cables or in kind.

Tangles, knotsand tears

Headphone cable, which is one thing to make music on the phone, which is slightly reduced. And if they are not pulling and pulling from the inside of the jacket or pants pocket, dangling freely, for a temporary prone fingers, plant or pedestrians. And who wants to fiddle with a hook to the event, while traveling or in a hurry?

There are some advantages, even if connected:

The connections are final and clear - you know whenand if you are connected to your iPod or music player. And if there is a problem where you hear nothing, there is probably pulling out, and, of course, we know how to solve the problem. No digital connection to rely on it - even if allocate ports for digital wireless headphones, wireless and free-roaming, but not always reliable. Many things are possible to go wrong with digital connections, a connection can be limited in its bandwidth can be hidden or onlyto drop everything. While in wired headphones, are mobile and rely only play anywhere to connect to the headphone jack on your music device.

Wired headphones to do the job and the sound quality is brilliant, but because you wear a sling? Why not opt ​​for something less appropriate, because they do not wander around for a while ', without wires?

Free Roaming

Without cable, you will be able to move freely without worrying Disconnect the headphonesjack. This capability will be provided through innovative wireless technology known as "Bluetooth", a short-range wireless communication system to replace wires and cables connecting portable and / or fixed electronic devices. With this invention technologically sound are the options to be evaluated and considered attractive.

Some obvious advantages of wireless audio:

So long, unsightly wires and masses - no longer needin connection with the cable to play music devices, or watch a dense mass of cables, connectors and cables. Goodbye and bon voyage! High quality digital connections - they are different frequencies in the audio and wireless devices differ in their quality headphones. But for the most part, provide connections for connecting digital spectrum award. Some advanced wireless headphones actually use a technology called Adaptive Frequency Hopping AFHwhich includes the headphones do work for you in choosing the best channels, find that they are trying to change, and only on channels untouched. Total diversity and mobility - Whether you prefer wireless headphones for portable music players, or only for domestic use (eg, theaters, TV, radio and home), are the most comfortable luxury after sliced ​​bread. The ability to mute and TV at home to look for other head for a ride into town with music to the ears or the situation, the music player where and when to listen, without having to fight the battle with the wires, well, it's very liberating experience. The possibilities are endless, and set no limits mobility.

Not for wireless headphones or audio equipment to get more constrained. Will allow you to fulfill your audio experience, not to drive you crazy, you cut the cord and free. If you're curious to know the options between wired and> Wireless audio options, especially in connection with the headphones, you can now choose which option is best for you. Choose a sling or run away.

Music without wires? - A look at the Wireless Audio Transmitter

The elimination of the large mess of cables has led to a wide range of wireless audio transmitter products over the years that promise to solve your home audio equipment. We'll look to see if the latest products to keep their promises to eliminate cable clutter, and we consider it as a change in technology has had an impact of these products.

Wireless transmission of music with the launch of commercial radio broadcasting began severaldecades ago. FM radio is still, though some recent technologies such as satellite radio and digital radio formats like HD Radio and DAB radio have begun to replace conventional FM radio popular. Today, a variety of consumer devices such as wireless microphones are available, wireless surround sound kits, Bluetooth audio transmitter, baby monitors, etc., to eliminate the cable through the wireless transmission of audio.

Wireless Headphone Ipod

One of the key applications for wirelessThe audio is music throughout the house and the creation of speakers without running microphone cable, which is a big problem in houses that are not connected to the audio distribution. Not every technology is ideal when it comes to wireless audio as we are coming out.

Consider the conventional technique, at first sight: FM broadcasts. Audio FM transmitter to send the audio signal through a radio frequency, which is evolving on the audio signal frequency. This method is calledFrequency Modulation or FM shortly. The biggest advantage of FM transmitters is their simplicity and their cost and coverage. As a result of using the most current 900-MHz wireless transmission of FM headphones. However, FM has serious drawbacks.

The first is the fact that the transmission of noise and then it will resume some hiss or static. The amount of noise actually varies depending on the location of the radio or receiver. This is due to the fact that the radio-Signal bouncing off the walls and stand in different places. This phenomenon is called multi-fading. Some wireless FM transmitter with two antennas in an experiment with this phenomenon (diversity) receiver to deal with. Also, just pick up FM interference transmissions from wireless devices and other products.

Bluetooth-based audio networks have recently gained popularity. Bluetooth is a popular wireless protocol, which wasDesigned primarily as an interface between the computer peripheral products. Bluetooth audio transmitter converts the audio signal into digital information and then transmitted via the Bluetooth protocol. Bluetooth is standardized fairly robust in terms of interference in the well. Bluetooth is, but some problems in terms of wireless audio, because they were not originally developed for wireless audio streaming. The first disadvantage is the limited range, usually 30 feet or less would be.The second problem is the fact that Bluetooth is not enough space to transmit CD-quality audio and compressed so that the sound at first. This compression causes a loss of audio quality depending on the degree of compression. The last problem is the fact that Bluetooth is a delay in the signal (also known as latency), which is a problem when used in conjunction with the video, because the sound is no longer used synchronously or imagine in a surround sound setup where some of the speakerswould be out of sync with the hard-wired speakers.

Satellite radio and digital terrestrial radio technologies offer a high range, but on a vast audio-compression leads to a deterioration of the audio signal and an audio delay of several seconds.

New technologies to transfer digital audio without compression. Avoiding compression audio signal to maintain the original quality. The audio latency of some of these products is less than 1 ms, and then theseTechnologies used in wireless speaker kit for home theater configurations.

Through the use of error correction, these technologies with the interference of competing wireless devices vital to cope in today's noisy environment. Some stations operate at 5.8 GHz frequency This space is less crowded than 900 MHz or 2.4 GHz, resulting in further improvement in terms of reliability. Unlike Bluetooth, able to work any number of wireless receiversfrom a single wireless audio transmitter, which is a concern in the distribution of audio to multiple rooms in a house.
