Besides the availability of the wireless headphones / stereo-phones/headsets in the market, old and weird headphones available at home can be made wireless by some expenditures and available tools at home just by understanding the simple technical details and circuits. They are very convenient to use and are ideal for watching movies, listening music without sitting near to a computer or a T.V. A wireless headphone does not require any wires or cables. They only have a transmitting unit known as the base unit. The audio device is connected to the base unit and the sound is transmitted from the base unit to the headphone with the help of radio waves or infrared rays. The transmitter emits the waves and the headphones receives it and converts it into sound which we in-turn hear in the form of sound. Both, the headphone and transmitter are battery operated.
Headphones initially originated from the earpiece and were the only way to listen to electrical audio signals before the amplifiers were developed. The main requirements for making a wireless headphone are described as follows.
- Old Headphone: an old and a weird headphone that is of no use.
- Bluetooth Device and speakers: with which the headphones are to be connected.
- Soldering stuff: a soldering iron, soldering flux, soldering wires of various gauges, de-soldering pumps.
- Pliers, screw drivers,cutting blade: for opening and sealing of the devices in use.

Opening of the headphones: Open the wired headphone with the help of a screw driver and take out the receiver and cut open the wires from the receiver. Brush the wires a little.
Opening of the Bluetooth speakers: Take the speakers of the Bluetooth device and open them. Remove the wires and solder the brushed wires taken out from the waste headphones and solder them with the help of soldering stuff onto the Bluetooth speaker.
Removal of insulation: Now remove the insulation from the back side of the headphone wire soldered on to the speaker with the help of a plier so as to make the inner wires visible.
Soldering the wires: Join both the ground wires and solder them with the help of a soldering stuff (soldering iron, soldering flux, soldering wires of different gauges). Now you are left with three wires the left terminal wire (green), red terminal wire (red) and a common ground wire (green).
Opening of the Bluetooth device: Now, take your Bluetooth device and open it too. Take out the prototyping board from it. Remove the battery too. View all the connections in the board properly. It consists of a left terminal that is of green color a right terminal that is of red color and a ground terminal that is of green color too.
Connections: Make the connections of the prototyping board of the Bluetooth device with the headphones. Connect the green wire of one headphone with the green (negative) terminal, red wire of the second headphone with the red terminal (positive) and ground common wire of the headphones with the ground terminal.
Replacing the board: Place the prototyping board back into the Bluetooth case along with the battery and make one hole on each side of the case so as to take out the wire of the headphones from each side separately.
Connecting the device with the charger: Connect your Bluetooth device with a portable charger, for external charging. Connect it to your phones or music systems and enjoy movies and music.
ADVANTAGES AND DISADVANTAGES OF WIRELESS HEADPHONES
Long distance operations: such headphones eliminate the use of wires and cables.
Light weight and comfortable: these are very light weight and comfortable to carry and even convenient to use. Some of them have an amazing battery life.
Freedom of movement: one of the main advantage they provide is that the person carrying them can go from one place to the other freely as the signals can cross the walls and furniture’s.
Increases the quality of the audio: they provide high quality audio with an excellent bass and treble, as the sound travels through two channels and is distributed equally.
Reliable: they provide durability and reliability as the user does not have to worry about the wires and the codes being cut or broken down.
Speed: altering the controls on headset is considerably quicker than using the commands on the mobile phone. This is particularly useful while travelling if we suddenly need to pause the playback.
Range management: the user sometimes, has to face problems like breaking up of sound if he/she steps out of the range.
Battery quality and life: the battery can also cause a problem sometimes. Long term usage can make the battery dead creating irritation.
Expensive: good wireless headphones cost much.
Affects the pitch of the sound: the headphone connected to the mobile phone produces sound that has to be re-encoded to suit the additional audio controls of the headset that may affecting the pitch of the sound.
Confusing functions: many of the headsets have many playback functions that enable the user to carry out multiple functions including shipping tracks, volume control, pausing the sound and replaying the tracks that are generally controlled by a single button on the Bluetooth device. This may sometimes leave the user confusing.
My cause deafness: using headphones at very high volumes can cause temporary or permanent hearing impairment as the headphone volume often has to compete with the background noise especially at the loud public places.
Headphones have multiple applications. They are used with stationary CD and DVD players, home theaters, PC’s, digital audio players, mp3 players, and mobile phones. Bluetooth/ Wi-Fi headphones /Cordless headphones receive radio or an infra-red transmission link like FM. These are used with events such as silent disco or silent gig.
Thus, normally available headphones at home or weird headphones can be reused and converted to wireless just by the use of simply available home equipments and a little bit of technical knowledge that saves extra expenditure and prevents anything from getting wasted.
