ARTICLE BEGINS
There was a time when listening devices had to be connected with wires in order to provide the best-quality sound. Today, wireless technology has taken over, leading to smaller, better and even cheaper devices.

The foundations of wireless

Like many technological advances, wireless technology in one form or another had been developed long before it became available to the consumer. The history of wireless communication, however, can be traced back to the late 1900s, when remarkable engineers such as Michael Faraday and Heinrich Herz were working. Although we were used to some forms of wireless systems such as walkie-talkies and amateur radio communication, it wasn't until the advent of the mobile phone that consumer markets were truly identified. In today's technology-rich world, wireless technology has been applied to a number of fields, including listening devices.

The benefits of wireless

As far as listening devices are concerned, wireless technology allows those using listening devices to listen at greater distances and with greater quality, whilst also being able to install the devices with less hassle than before. Today' wireless devices can simply be placed on a surface, or incorporated into everyday objects in order to transmit audio information to the listener. Advances in technology also mean that wireless signals can travel quickly and clearly and, as some listening devices use the mobile phone system known as GSM, operators can dial into the device and listen from their phones at any time. In short, wireless makes the process of using listening devices faster, clearer and easier. A wireless system is less likely to break down, less likely to be discovered and less likely to have its transmission interrupted. What's more, wireless technology can also be used for still and moving picture transmission, further expanding its use in viewing and listening devices for all situations.
