Wireless Headphones

When cordless [mobile] phones first came to Uganda in the late 1990s, it was monumental and it indeed took a bit of time for the Africans here to come to terms with this idea that you could talk to someone miles away without a wire connecting one to the other.

Anyway, scientists have never let up the idea. The mission has since been to completely do away with wires and, of course, where there’s a will there’s always a way. In the 21st Century, we can ably listen to music or radio, for that matter, without any wires from the radio to the speakers. This is possible with the new technology of cordless headphones that has invaded our space. The question now is with how it all works.

According to Peter Peak, an ICT expert in Mukono, wireless headphones are headphones that connect to a device, such as a smartphone, stereo speaker, television, computer, or other electronic devices without using a wire or cable.

As a matter of fact, wireless headphones are now used by millions of people every day for work, interaction or entertainment. For example, wireless headphones are popular with people who work at call centers; for it frees you to move around without having to worry about cords/wires.

People doing a workout at the gym or in front of their TV in the living room love the freedom of wireless headphones. They are also perfect for people who want to watch late-night television without disturbing others.

How Wireless Headphones Work

Wireless headphones work by connecting, or pairing, with the device you want to use, through a radio or electromagnetic signal. Many devices use Bluetooth technology to make connecting easier for the user.

Devices with Bluetooth technology can connect and exchange data over very short distances using radio transmissions. Headphones with Bluetooth also let you connect to multiple devices simultaneously.

A product with Bluetooth technology has a tiny computer chip inside that contains the Bluetooth radio, and software that makes connectivity between devices possible.

So when Bluetooth-enabled products, such as a cell phone and headphones, are in close proximity to each other, they connect, or pair. This enables you to talk on the phone or listen to music without wires.

Connecting a wireless headphone differs depending on the device you are using, but it’s easy once you know how.

Advantage Of The Wireless Technology

Cordless headphones operate in the same basic way regular headphones do, except that they have a built-in radio frequency receiver. This eliminates the wire necessary to plug your headphones into a computer or other piece of electronic equipment.

As opposed to being forced to stay within a certain distance from an audio source, with cordless headphones you’re free to walk around within range of the transmitter. Cordless headphones are also ideal when traveling.

You can use them with any audio device that has a standard-size headphone jack. This allows you to plug your cordless headphones into any device you find.

How Signal Is TransmittedTo The Headphones

Cordless headphones come with two distinct and necessary pieces of equipment: the headphones themselves and the radio transmitter. The transmitter plugs into the headphone jack of a piece of audio equipment. It converts the audio signal output into a radio frequency, and then transmits it over the air.

Cordless headphones may be battery-operated or rechargeable. They have a radio receiver built into the base. This picks up the signal emitted by the radio transmitter and converts that signal from a radio frequency back into audio information.

That audio information then plays over the headphone speakers just as it would with regular headphones. Cordless headphones essentially operate in the same way as a set of wireless home theater speakers.

Health Hazards

All is well that ends well, they say. The wireless technology is very new and it is really impossible to claim that all is well yet. It instead poses serious health threats, because of the complexities of the technology used in it.

Peter Peak emphasizes that most of the wireless headphones use the Bluetooth technology. Bluetooth is wireless technology that is employed for exchanging data over short distances. Which basically means it’s a wireless system. This means that to achieve their purpose, Bluetooth transmits electromagnetic waves at rather high frequency levels.

Moreover, when you use a Bluetooth earpiece device you’re exposing yourself to an additional source of radiation. This is so, because your cell phone acts as a relay by emitting radiation between the cell phone tower and your correspondent. When you add Bluetooth into the equation your cell phone also emits another form of radiation, Bluetooth radiation, between your cell phone and your Bluetooth earpiece.

Your radiation exposure with a Bluetooth headset is the sum of cell phone radiation plus Bluetooth radiation. So Bluetooth radiation in itself may be less dangerous than cell phone radiation but when you use a Bluetooth earpiece you are always exposing yourself to radiation from both devices. In the long run, brain cells are damaged and adverse effects could arise. As it is now, the most viable solution to this is to endeavor to limit the amount of time that is spent with the wireless headphone.
