Bluetooth earphones today have become a necessity for most people using a portable device – be it mobile phone, an iPod or any other music system that supports Bluetooth. Bluetooth earphones are wireless earpieces that can be connected to your mobile device or your MP3 player, for hands-free usage. Bluetooth earphones will operate just like your regular headphone or headset, without the unwanted constraint of using a wire to connect the earphone with the device.

How do Bluetooth earphones work?

Your Bluetooth earphones connect to devices that use radio frequencies in the ISM band. ISM stands for Industrial, Scientific and Medical band. In order to avoid interference of your device with other devices that use the ISM band, such as microwaves and cordless phones, the Bluetooth device divides the band into 79 one-megahertz channels. Thereafter, the signal is made to shuttle between the 79 channels at a rate of 1,600 times per second.

Since all Bluetooth earphones work on the same basic technology, the difference between them depends on the quality of the speaker, the battery life, the design of the earphone and the comfort that it affords. If you go for a high-end Bluetooth earphone, you will get a number of added features. These features include as ambient noise blocking or automatic volume adjustment. Some Bluetooth earphones will even allow you to connect with a number of devices and then switch and alternate between them as and when you want to.

The Range of Bluetooth Earphones

Usually, the range of Bluetooth earphones is between 30-60 feet, depending on the strength of the signal. However, the more the strength of the signal, the more power consumption will take place. This is why for most practical purposes; low-power Bluetooth earphones should be enough. In some cases, Bluetooth devices can deliver even up to a range of 300 feet.

The advantages

A wireless Bluetooth earphone will help you to pair your A2DP-enabled Bluetooth music device, computer, or cell phone with the headphone. This means that you can listen to the track even when you are on move. The Bluetooth earphones have integrated control system that allows you to change the track list, adjust the volume of your music or your call and even take calls.

The great thing about a Bluetooth earphone is that there is no need for you to buy Bluetooth earphones from the same manufacturer of your mobile device. This is because each Bluetooth device is compatible with all other kinds of devices that carry the Bluetooth logo. Bluetooth earphones allow you to lead a hassle free life, without having to bother about messy wires and tangles that are hard to unknot.
