Cordless earbuds are often referred to as a wireless earbuds and may allow you to move around freely without actually being restrained by a cord, or set of wires while you are listening to your home stereo, television, iPod or MP3 player. In addition to this cordless earbuds will also mean that you do not have to carry around a portable audio device. Cordless earbuds typically operate via a radio frequency or through infrared technology. Both these forms of technology will rely on a source transmitter or a base station. The base station will typically be connected to your audio source that will usually have either a headphone jack or stereo RCA output.
Cordless earbuds will have a built-in amplifier and receiver. Signals will be received in the form of radio waves and then they will be converted into sound waves by the amplifier. In order to power both the receiver and amplifier a set of cordless earbuds will typically use batteries. When you are not using your earbuds they can be docked in the base station and recharged if the specific set of earbuds you have allow for this.
The radio frequency technology that is used in cordless earbuds works very much like a cordless house phone. This technology will allow you to move freely throughout your home, although you will always need to stay within range of the base transmitter. The majority of base transmitters are able to send a signal from 100 feet to 300 feet. As radio frequency is known to have a robust signal you should find that this gives you an extremely high quality audio signal. With that said, radio frequency technology is prone to interference. This will usually happen when another radio-frequency device is using the exact same frequency, which will usually create static and eventually this will affect the overall quality of sound.
To overcome the problem of interference you can actually set a specific channel frequency for both your base transmitter and your cordless earbuds. However, you should be aware that if you stray beyond the actual range of transmission, you will typically lose any signal. In the case of infrared cordless earbuds, they will receive information via a signal which is usually transmitted via an infrared light beam from the base station. In order for your earbuds to work you must always remain within visual range of the base transmitter. The maximum range for most infrared systems will usually be no more than 30 feet. Although the use of infrared systems may seem slightly restrictive in comparison to radio-frequency, you will find that the audio quality is far better. Additionally, infrared technology uses far less energy than most radio-frequency devices. This, of course, means that it will be far more economical and cost-effective.
Cordless and wireless earbud technology is now multifaceted. Their initial inception was based around making music sharing far easier and more convenient. However, they are now being used in many home offices and standard office applications. The most common use in this environment will be for a telemarketer or someone who spends long periods of time on the telephone. Cordless earbuds and this specific technology has also been introduced into many schools. This will enable a teacher to divide their class in two separate groups, whereby each group will share the media from a single device.
There has been another recent introduction in the cordless earbud industry and this is, of course, a Bluetooth device. Bluetooth earbuds will typically need to be compatible with other Bluetooth devices such as your cellphone or MP3 player. If you do not have a device that is compatible you will, once again, require a transmitter. Bluetooth earbuds are much the same as infrared technology and will usually have a range of up to 30 feet. They use what is known as adaptive frequency hopping spread spectrum (AFH) which will typically seek out a suitable frequency to transmit on. You will also find a Bluetooth earbuds are far less prone to interference than radio-frequency earbuds.
Cordless earbuds are a fantastic invention and they merely add mobility to your overall audio listening experience. This will allow you to listen to your favourite music without having to worry about disturbing other people. At the same time you will not be restricted by cords or a cable. Cordless earbuds have come a long way since the original models were introduced many years ago. They have a vastly improved sound clarity, an increased range and are far more portable than ever before. Additionally, you now have a choice of three separate forms of technology, namely cordless, wireless and Bluetooth. Prior to making a decision as to which form of earbuds you should purchase, it is important that you are aware of what they can and cannot do. With that said, this new form of cordless technology can only ever enhance your overall audio experience.
