When i was small, i usually think how these Wireless headphones work. What magic makes them work! But now i had figured out a simple way to make one with your own old (Plug-on headphones) a wireless one. Though it will work by plugging in too .It is ideal for watching movie or listening to music without sitting close to computer or T.V. It's range is not good because if it's range will be more than 5 meters you will have to buy a license But you can use it anywhere at your home cause it's signal can only reach up-to 5 meters of diameter. So, no need of buying license. I hope you will enjoy it and for staying tuned to me be a subscriber and

Please vote for me.I will appreciate it and thankful too.

Step 1: Thechnical Details

Once you've decided to make your own wireless headphone you need some knowledge about what we are going to do. First of all you need a headphone (An old one or which you are using). The headphone should have enough inner space (I mean to say that when you open the headphone the stuff "The radio receiver module" which we are going to install in in fit in easily). You have to buy a small radio receiver module be sure to use the smallest with auto or manual tuning. Now what we are going to do is install the radio module inside the headphone and then tune it to your Emitter's frequency and grab some of the controls of the radio module out of the headphones so that you can tune it without opening the whole headphone again. Now we move on to the Emitter, you have to make your own Emitter. It's a simple Electronics project. The circuit consists of one 2N2222 or BC547 transistor (You can use one or the other depending on the availability, But i prefer using a 2N2222 transistor) used as a base amplifier which amplifies the audio signals form your computer or T.V. and converts it into FM signal. The emitter's frequency is between 87.5 to 108.0 Mhz (Common radio frequency) and can be tuned to any frequency by changing the value of the 20-40 picofarad variable capacitor. Now FYI it's rage in not good up-to 3-4 rooms or 5meters so i my view you won't need a license for the frequency usage. You can emit any kind to audio signal from T.V, Computer, MP3 player , Mobile Phone , etc.

Thank you for all your work. Here in Canada's fourth or fifth largest city there are only one or two places which sell individual components. People are so used to buying ready made stuff because they give instant gratification. Experimenters order parts from the US and pc boards from Iran or India because it so much cheaper even with exhorbitant postage rates. I've experimented all my life even if my projects didn't work. I used "surplus" parts and had to learn the color codes or whatever. I also find I often have to "repair" new items due to faulty soldering from too cheap prices. In North America, very little gets fixed, just binned and sent back to where it was made. Wonderful. So it was inspiring to see your plans and work and prodded me to be less consumerist. Again than you.

Thank you too!

You could place multiple transmitters all around your house all connected to the same audio source, all tuned at the same frequency, so you have in your whole house receive range.

Could you give me some video. I have a poor imagination so I can't understand your pictures. Thank you very much

samaddon (author)  vietanisme6 months ago

Sorry dear but it was destroyed because of mishandling ! So i can't give a video now, i wish you had asked few weeks ago! But the video i gave is also enough to replicate it! If you have any questions even the little ones feel free to pm me!

What a pity . But I'll be very appreciate if you give me (and every one) a detailed instruction about the transmitter. Thank you again

samaddon (author)  vietanisme6 months ago

for live instruction you can skype me or get me on facebook.

My skype user id is: sami.maman.samad

If I could do this I whould make it. I Will have to cry in the corner...

samaddon (author)  dmoonen9 months ago
well it's easy for those who know electronics a little bit! in your case you could learn electronics or i have another simple way if you can buy things from ebay i can get it done by you!
samaddon (author)  samaddon9 months ago
You could buy or search for parts all around and you will will get some of them! ut about the radio transmitter making is quiet cheap but buying will cost you around $25-30.
dmoonen samaddon9 months ago

I could buy it all by ebay. But the price will be important...

does it work in stereo mod
samaddon (author)  arun ramachandran1 year ago
Yes but you need to make a good FM transmitter circuit using an BA1404 IC!
good work..now i'm developing a small project with headphone..better if i can add a wireless stereo connectivity to it..
samaddon (author)  arun ramachandran1 year ago
Yes but you need to make a good FM transmitter circuit using an BA1404 IC!
rseballos1 year ago
how can i change the frequency of the emitter? by changing the value of the variable capacitor? or the inductor? and lastly, do you have a circuit diagram for fm receiver? can i used this http://www.electroschematics.com/5150/tiny-fm-radio/ circuit instead of buying a radio receiver module?
samaddon (author)  rseballos1 year ago
Yes you can tune it by changing the value of C2 don't touch the inductor it will be messy! and the receiver circuit you gave is not very well and you will suffer a lot so i think use a BA1404 IC circuit or another IC circuit not the circuits with transistors only!

I really feel like trying, but I already have a pair of Jabra Revo wireless headphones. So maybe I should try something els;-)
rseballos1 year ago
Helo sir.. just wanna if i can used it in my circuit.. i have an IC that produce sound/speech to the speaker. Now i want to remove the speaker and make it wireless communication between my circuit and my headphone. it that possible?
should i connect the emitter to the output of the IC?
samaddon (author)  rseballos1 year ago
yes it is possible just name the IC and get me some images to see you speaker!And don't call me sir i am 16!

PDF won't download.
it comes up with the page where the pdf should be displayed, but it just gives it as 0bytes. what happened?
samaddon (author)  MelPhleg1 year ago
Yes it's the same with me! Please report to instructables Bug-Report community

Great innovative "cut & paste" job !
will it be possible to use my smartphone as a radio receiver?
samaddon (author)  ViperSniper1 year ago
Yeah! no matter just search your frequency by tuning! but you don't have to ask 5 times! or i think your mouse left click button is quiet loose you can put a simple paper between the switch and the upper casing button or you can change you click button!
Thanx for the reply and the mouse fix. Sorry for posting it 5 times, I commented via my phone and it lagged a little, sorry about that.
samaddon (author)  ViperSniper1 year ago
No! need of sorry i faced the same problem with my mouse and it really got me suffered.

Funny you mention that, I do actually read a lot of questionable material, out of curiosity and not affiliation, but this is the type of stuff big bro can't wait to get their hands on.. sooo.... but if there's no way to manipulate the radio signal to somehow hack into to the device then I guess it's fine.
this is great
paskalip1 year ago
Great idea, but if you're keeping the headphones cable why don't you just connect it to the radio and be done with? It will still be a nice pair of portable speakers (and you could also connect your earphones or your speakers)
