We often take technological advancements for granted. Much of it has made our lives a whole lot easier, faster and more efficient. Personal headphones are a prime example of such technology and we owe their existence to the invention of the Telephone. Early in the 20th century, headphones were developed from the telephone earpiece since this was the only method of listening to audio signals.

Some of the earliest headphones were those designed and manufactured for people working in the Radio industry. These early headphones used ‘moving iron drivers’ that consist of magnets and fine wire for vibrations to travel down. These early headphone designs were very uncomfortable and padding was not heard of – it felt like a heavy clamp was sitting on your head! The earliest loudspeakers were primarily designed for speech and were using the same technology. This loudspeaker technology is still used today in some small speakers where low costs are needed and sound quality is not so important.

In early powered radios, headphones were connected directly to high voltage battery terminals since they required an immense amount of power to be useful devices. This meant that users were at risk of receiving an electric shock if they touched the bare headphone connections, whilst commonly having to adjust the headphones…ouch! The ‘Brandes Radio’ headphones are an example of these early versions of headphones.

There were many incremental advancements in sound and headphone technology over the last century. In the 1980’s it was common to come across a supra-aural headphones. These headphones have ear pads for comfort, which sat on top and against the ears rather than around them. Next to follow were the immensely popular earbuds or earphones to be more precise. These types of headphones were used throughout the 90’s and break of the new century. As you may have guessed, these headphones sat on the inner edge of the ear and directed at the ear drum. These were less powerful than over-head headphone designs but meant they were discreet. The main problem with these new headphones was that they often fell out of the ear and therefore would interrupt your listening experience every time you had to put them back in. How annoying! Soon after this became clear and further improvements in sound and headphone technology, the canal headphones were born. These provided a stern fit and a new phenomenon called dubbed Sound-isolation Technology.

So here we are in the early 21st century with headphones that have come a long way. We owe a lot to these every day devices that are essentially now a requirement for everyone since mobile phones, personal mp3 and many more devices require headphones to be used. There are many different types of headphones available to suit individual needs and they continue to be developed. So the next time you’re looking to buy headphones remember what they went through and you might just appreciate them a little bit more!
